Particles in UPW are critical contaminants, which result in numerous forms of defects on wafer surfaces. With the large volume of UPW, which comes into contact with each wafer, particle deposition on the wafer readily occurs.
Once deposited, the particles are not easily removed from the wafer surfaces. With the increased use of dilute chemistries, particles in UPW are an issue not only with UPW rinse of the wafers, but also due to introduction of the particles during dilute wet cleans and etch, where UPW is a major constituent of the chemistry used.
Particle levels must be controlled to nm sizes, and current trends [ as of? While filters are used for the main loop, components of the UPW system can contribute additional particle contamination into the water, and at the point of use, additional filtration is recommended.
Common materials include nylon , polyethylene , polysulfone , and fluoropolymers. Filters will commonly be constructed of a combination of polymers, and for UPW use are thermally welded without using adhesives or other contaminating additives.
The microporous structure of the filter is critical in providing particle control, and this structure can be isotropic or asymmetric. In the former case the pore distribution is uniform through the filter, while in the latter the finer surface provides the particle removal, with the coarser structure giving physical support as well reducing the overall differential pressure.
Filters can be cartridge formats where the UPW is flowed through the pleated structure with contaminants collected directly on the filter surface. Common in UPW systems are ultrafilters UF , composed of hollow fiber membranes.
In this configuration, the UPW is flowed across the hollow fiber, sweeping contaminants to a waste stream, known as the retentate stream. The retentate stream is only a small percentage of the total flow, and is sent to waste. The product water, or the permeate stream, is the UPW passing through the skin of the hollow fiber and exiting through the center of the hollow fiber.
The UF is a highly efficient filtration product for UPW, and the sweeping of the particles into the retentate stream yield extremely long life with only occasional cleaning needed.
Use of the UF in UPW systems provides excellent particle control to single digit nanometer particle sizes. Point of use applications POU for UPW filtration include wet etch and clean, rinse prior to IPA vapor or liquid dry, as well as lithography dispense UPW rinse following develop.
These applications pose specific challenges for POU UPW filtration. For wet etch and clean, most tools are single wafer processes, which require flow through the filter upon tool demand. The resultant intermittent flow, which will range from full flow through the filter upon initiation of UPW flow through the spray nozzle, and then back to a trickle flow.
The trickle flow is typically maintained to prevent a dead leg in the tool. The filter must be robust to withstand the pressure and low cycling, and must continue to retain captured particles throughout the service life of the filter.
This requires proper pleat design and geometry, as well as media designed to optimized particle capture and retention. Certain tools may use a fixed filter housing with replaceable filters, whereas other tools may use disposable filter capsules for the POU UPW.
For lithography applications, small filter capsules are used. Similar to the challenges for wet etch and clean POU UPW applications, for lithography UPW rinse, the flow through the filter is intermittent, though at a low flow and pressure, so the physical robustness is not as critical.
The UPW forms a puddle between the lens and the wafer, improving NA, and the UPW must be extremely pure. POU filtration is used on the UPW just prior to the stepper scanner. For POU UPW applications, sub 15 nm filters are currently in use for advanced 2x and 1x nodes.
The filters are commonly made of nylon, high-density polyethylene HDPE , polyarylsulfone or polysulfone , or polytetrafluoroethylene PTFE membranes, with hardware typically consisting of HDPE or PFA.
Point of use treatment is often applied in critical tool applications such as Immersion lithography and Mask preparation in order to maintain consistent ultrapure water quality.
UPW systems located in the central utilities building provide the Fab with quality water but may not provide adequate water purification consistency for these processes. In the case when urea, THM, isopropyl alcohol IPA or other difficult to remove low molecular weight neutral compounds TOC species may be present, additional treatment is required thru advanced oxidation process AOP using systems.
This is particularly important when tight TOC specification below 1 ppb is required to be attained. These difficult to control organics have been proven to impact yield and device performance especially at the most demanding process steps.
One of the successful examples of the POU organics control down to 0. Available proprietary POU advanced oxidation processes can consistently reduce TOC to 0.
The semiconductor industry uses a large amount of ultrapure water to rinse contaminants from the surface of the silicon wafers that are later turned into computer chips. The ultrapure water is by definition extremely low in contamination, but once it makes contact with the wafer surface it carries residual chemicals or particles from the surface that then end up in the industrial waste treatment system of the manufacturing facility.
The contamination level of the rinse water can vary a great deal depending on the particular process step that is being rinsed at the time. A "first rinse" step may carry a large amount of residual contaminants and particles compared to a last rinse that may carry relatively low amounts of contamination.
Typical semiconductor plants have only two drain systems for all of these rinses which are also combined with acid waste and therefore the rinse water is not effectively reused due to risk of contamination causing manufacturing process defects.
As noted above, ultrapure water is commonly not recycled in semiconductor applications, but rather reclaimed in other processes. There is one company in the US, Exergy Systems, Inc.
of Irvine, California, that offers a patented deionized water recycling process. This product has been successfully tested at a number of semiconductor processes.
The following definitions are used by ITRS: [6]. Some semiconductor manufacturing plants have been using reclaimed water for non-process applications such as chemical aspirators where the discharge water is sent to industrial waste.
Water reclamation is also a typical application where spent rinse water from the manufacturing facility may be used in cooling tower supply, exhaust scrubber supply, or point of use abatement systems. UPW Recycling is not as typical and involves collecting the spent manufacturing rinse water, treating it and re-using it back in the wafer rinse process.
Some additional water treatment may be required for any of these cases depending on the quality of the spent rinse water and the application of the reclaimed water. These are fairly common practices in many semiconductor facilities worldwide, however there is a limitation to how much water can be reclaimed and recycled if not considering reuse in the manufacturing process.
Recycling rinse water from the semiconductor manufacturing process has been discouraged by many manufacturing engineers for decades because of the risk that the contamination from the chemical residue and particles may end up back in the UPW feed water and result in product defects.
Modern Ultrapure Water systems are very effective at removing ionic contamination down to parts per trillion levels ppt whereas organic contamination of ultrapure water systems is still in the parts per billion levels ppb.
In any case recycling the process water rinses for UPW makeup has always been a great concern and until recently this was not a common practice. Increasing water and wastewater costs in parts of the US and Asia have pushed some semiconductor companies to investigate the recycling of manufacturing process rinse water in the UPW makeup system.
Some companies have incorporated an approach that uses complex large scale treatment designed for worst case conditions of the combined waste water discharge. More recently new approaches have been developed to incorporate a detailed water management plan to try to minimize the treatment system cost and complexity.
The key to maximizing water reclaim, recycle, and reuse is having a well thought out water management plan. A successful water management plan includes full understanding of how the rinse waters are used in the manufacturing process including chemicals used and their byproducts.
With the development of this critical component, a drain collection system can be designed to segregate concentrated chemicals from moderately contaminated rinse waters, and lightly contaminated rinse waters. Once segregated into separate collection systems the once considered chemical process waste streams can be repurposed or sold as a product stream, and the rinse waters can be reclaimed.
A water management plan will also require a significant amount of sample data and analysis to determine proper drain segregation, application of online analytical measurement, diversions control, and final treatment technology.
Collecting these samples and performing laboratory analysis can help characterize the various waste streams and determine the potential of their respective re-use. In the case of UPW process rinse water the lab analysis data can then be used to profile typical and non-typical levels of contamination which then can be used to design the rinse water treatment system.
Stainless steel remains a piping material of choice for the pharmaceutical industry. Due to its metallic contribution, most steel was removed from microelectronics UPW systems in the s and replaced with high performance polymers of polyvinylidene fluoride PVDF , [1] perfluoroalkoxy PFA , ethylene chlorotrifluoroethylene ECTFE and polytetrafluoroethylene PTFE in the US and Europe.
In Asia, polyvinyl chloride PVC , chlorinated polyvinyl chloride CPVC and polypropylene PP are popular, along with the high performance polymers. Contents move to sidebar hide. Article Talk. Read Edit View history.

Dell Cameron. Parker Hall. Zoë Schiffer. In the 21st century, sand has become more important than ever, and in more ways than ever. This is the digital age, in which the jobs we work at, the entertainment we divert ourselves with, and the ways we communicate with one another are increasingly defined by the internet and the computers, tablets, and cell phones that connect us to it.
None of this would be possible were it not for sand. The quantity of quartz used for these products is minuscule compared to the mountains of it used for concrete or land reclamation.
But its impact is immeasurable. About million years ago the area was located south of the equator. The friction of that colossal grind generated heat topping 2, degrees Fahrenheit, melting the rock that lay between 9 and 15 miles below the surface.
The pressure on that molten rock forced huge amounts of it into cracks and fissures of the surrounding host rock, where it formed deposits of what are known as pegmatites.
It took some million years for the deeply buried molten rock to cool down and crystallize. Thanks to the depth at which it was buried and to the lack of water where all this was happening, the pegmatites formed almost without impurities. Generally speaking, the pegmatites are about 65 percent feldspar, 25 percent quartz, 8 percent mica, and the rest traces of other minerals.
Meanwhile, over the course of some million years, the plate under the Appalachian Mountains shifted upward. Weather eroded the exposed rock, until the hard formations of pegmatites were left near the surface.
Native Americans mined the shiny, glittering mica and used it for grave decorations and as currency. American settlers began trickling into the mountains in the s, scratching out a living as farmers. A few prospectors tried their hands at the mica business, but were stymied by the steep mountain geography.
Once this artery to the outside world was finally opened, mining started to pick up. Locals and wildcatters dug hundreds of shafts and open pits in the mountains of what became known as the Spruce Pine Mining District, a swath of land 25 miles by 10 miles that sprawls over three counties.
Prosperity came to Spruce Pine. The town quadrupled in size in the s. At its peak, Spruce Pine boasted three movie theaters, two pool halls, a bowling alley, and plenty of restaurants. Three passenger trains came through every day.
The problem was separating those minerals from the other ones. For years, locals would simply dig up the pegmatites and crush them with hand tools or crude machines, separating out the feldspar and mica by hand.
The quartz that was left over was considered junk, at best fit to be used as construction sand, more likely thrown out with the other tailings. You dump that mix in a tank, add water to turn it into a milky slurry, and stir well.
Now pipe a column of air bubbles through the slurry. A paddle wheel skims off the froth and shunts it into another tank, where the water is drained out. Voilà: mica. The remaining feldspar, quartz, and iron are drained from the bottom of the tank and funneled through a series of troughs into the next tank, where a similar process is performed to float out the iron.
Repeat, more or less, to remove the feldspar. It was the feldspar, which is used in glassmaking, that first attracted engineers from the Corning Glass Company to the area.
Woodbury in The Glass Giant of Palomar. So slowly did the ingredients melt that only four tons a day could be added. Little by little the fiery pool spread over the bottom of the furnace and rose gradually to an incandescent lake 50 feet long and 15 wide. Its unprecedented power led to important discoveries about the composition of stars and the size of the universe itself.
It is still in use today. Significant as that telescope was, Spruce Pine quartz was soon to take on a far more important role as the digital age began to dawn.
William Shockley, a pathbreaking engineer at Bell Labs who had helped invent the transistor, had left to set up his own company in Mountain View, California, a sleepy town about an hour south of San Francisco, near where he had grown up.
But the area known at the time as the Santa Clara Valley was still mostly filled with apricot, pear, and plum orchards. It would soon become much better known by a new nickname: Silicon Valley. At the time, the transistor market was heating up fast.
Texas Instruments, Motorola, and other companies were all competing to come up with smaller, more efficient transistors to use in, among other products, computers. The first American computer, dubbed ENIAC, was developed by the army during World War II; it was feet long and 10 feet high, and it ran on 18, vacuum tubes.
Transistors, which are tiny electronic switches that control the flow of electricity, offered a way to replace those tubes and make these new machines even more powerful while shrinking their tumid footprint.
Semiconductors—a small class of elements, including germanium and silicon, which conduct electricity at certain temperatures while blocking it at others—looked like promising materials for making those transistors. When they opened the kiln doors weird streaks of orange and white light went across their faces.
they lowered a small mechanical column into the goo so that crystals formed on the bottom of the column, and they pulled the crystal out and tried to get a grip on it with tweezers, and put it under microscopes and cut it with diamond cutters, among other things, into minute slices, wafers, chips; there were no names in electronics for these tiny forms.
Shockley became convinced that silicon was the more promising material and shifted his focus accordingly. Shockley was a genius, but by all accounts he was also a lousy boss. Within a couple of years, several of his most talented engineers had jumped ship to start their own company, which they dubbed Fairchild Semiconductor.
At almost the same time, Texas Instruments developed a similar gadget made from germanium. In , Noyce left to found his own company. He called it Intel, and it soon dominated the nascent industry of programmable computer chips.
Those tiny electronic squares and rectangles are the brains that run our computers, the Internet, and the entire digital world. Google, Amazon, Apple, Microsoft, the computer systems that underpin the work of everything from the Pentagon to your local bank—all of this and much more is based on sand, remade as silicon chips.
Making those chips is a fiendishly complicated process. They require essentially pure silicon. The slightest impurity can throw their tiny systems out of whack.
Finding silicon is easy. It shows up practically everywhere bound together with oxygen to form SiO2, aka quartz. The problem is that it never occurs naturally in pure, elemental form. Separating out the silicon takes considerable doing.
Lump quartz is also sometimes used.
