Filson: Excellent Semiconductor Gas Filters Increasing Your Yields
Filson semiconductor gas filters are preferred products applied to the semiconductor industry. It not only purifies the gas passing through the system but also effectively protects the critical components in semiconductor gas distribution systems.
Sintered Stainless Steel Filter for Semiconductor
Filson semiconductor gas filters are also called semiconductor metal filters for all our products are made of metals. The most frequently used materials are stainless steel, usually 316L, nickel, and Hastelloy to meet the demanding requirements.
Compared to other common semiconductor gas filters in the market, Filson metal filters are more durable. They have higher corrosion resistance and can withstand thermal conditions up to 450℃.
In addition, experiencing a precisely controlled sintering process, Filson semiconductor gas filter has higher filtration efficiency, and as a result, it can easily remove a particle as small as 0.0015 µm which is a big progress infiltration field.
Semiconductor Processing Using Gas Filters
Another advantage brought by the Filson semiconductor gas filter is that it definitely won’t cause secondary pollution to the gas. Unlike nylon, PTFE or nanospun polypro gas filter for semiconductors, these sintered metal gas filters from Filson have no risk of powder or particle drop which may lead to other problems in the manufacturing process.
There are several forms of contaminants existing in bulk and specialty gas supplies, they are particulates, molecular contaminants, and even so-called historically benign contaminants. Using Filson quality semiconductor gas filters, they are quite easy to deal with.
IT classify the contaminants further, in general, they include but are not limited to moisture, acids, bases, refractory compound, and organic molecules. Of course, the contaminants can be generated during the working process.
Helium Gas Purification System
For example, if introducing oxygen ( O2 ) unintentionally during the silicon ( Si ) ingot growth process, silicon dioxide ( SiO2 ) will be produced and its deposition will cause defects before wafer processing even begins. So it is necessary to equip a Filson semiconductor gas filter in the gas distribution path.
The two basic gas filtration and purification methods of Filson semiconductor gas filter are physisorption and chemisorption. The former is mainly to remove H2O and hydrocarbons and the latter is mainly to remove CO, O2, and other reactive oxides.
Filson semiconductor gas filters are all formed in a rather clean environment to make sure the quality of the final product. And under the support of particle-free, chemically clean, organic free handling and bagging, Filson semiconductor filters are proved to be used in the most demanding microelectronics applications.
Purification for Ultra High Purity Gas Delivery System
To reach and even exceed the high purity gas handling filtration requirements for the semiconductor industry, Filson semiconductor gas filters are rigorously tested before leaving the factory to ensure high filtration efficiency, precise flow control, and operational safety requirements.

Filson Filters for Semiconductor Applications
People Also Ask
Filters in semiconductors indicate gas filters applied to semiconductor manufacturing. The filter plays the important role in protecting expensive components in the gas purification system. Besides, it contributes a lot to filter gas used in the manufacturing process.
The semiconductor gas filter is designed and engineered into different shapes including sheet, square, and cylinder to meet customer specifications and match with the existing system requirements.
Semiconductor gas filter produced by Filson is generally made of metal materials experiencing a sintering process. You can select desired materials from stainless steel, nickel, and Hastelloy to satisfy your needs. Of course, other metal materials are also available to build filters for you.
Filson Semiconductor Gas Filters
You may find that most semiconductor gas filters in the market are white and are made of PTFE, nylon, or nanospun polypro. But here, at Filson, we only provide metal filters for your semiconductor devices.
There are many differences between PTFE membrane filter and metal filter, the main points are listed below:
- About price.
PTFE membrane filter is fairly cheap, while semiconductor metal filter is relatively expensive compared to the former one. That’s typical because of the raw construction materials.
- About quality.
PTFE membrane filter is far thinner than most manufacturers realize and can be torn during the operation process due to pressure fluctuation. When the thin filter becomes damaged, particle excursion happens and it will result in downstream process failures and contamination of the high purity gas.
However, the semiconductor metal filter wins this round. Regardless of the quality of raw metal materials, the metal filter is sintered of metal powder which has already ensured the compact construction of the product. And no powder drop means no new contaminants to the system.
- About performance.
For most manufacturers, the standard practice is to use PTFE membrane filters in semiconductor manufacturing, because they have low-pressure drops and they are quite cheap. Metal filters are featured by high temperature and pressure resistance and they are more accurate infiltration which can remove particles of 0.0015 µm.
- About life.
Though PTFE membrane filters are lower in price, their lives are incredibly short-lived. They take the risk of tearing and shedding which makes it necessary to change out within one year. If you purchase multiple PTFE filters in a short time, it seems not cost-effective.
In terms of metal filters, they have a much longer lifetime than PTFE filters. Even when being exposed to the most corrosive gas in semiconductor manufacturing, they can last up to five years. At the same time, they can perform well under oxidizing conditions due to the strong structure and good properties of materials.
You can choose the proper semiconductor filter for your application according to the points above. But it is obvious that a metal filter is more efficient and economical. The stable and reliable alternative to these risks brought by PTFE filters is sintered metal filters. Though they cost a bit more than PTFE filters, the benefits of metal filters go far beyond their face value.
Sintered Metal Filter vs PTFE Filter
When applying a semiconductor gas filter to your industry, you will find your semiconductors yields increased and the operation of the whole process becomes smooth and successful.

Choose the Right Filter for Your Application
Of course, it’s necessary to adopt a semiconductor gas filter in your application.
Semiconductors are the basis of most electronic circuits. And they exist in almost all electronic devices. The manufacturing of these integrated circuits, which is also called chips, is a complex design system, leading to a multi-step process.
The point is that the chips yield of these processes depends heavily on the effectiveness of semiconductor gas filters used in every step of wafer processing. The filter captures particulate matter during the operating process to a great extent which makes sure the final success.
High purity gases in multiple forms are used to create and clean semiconductor chips. They are transferred through a delivery system to silicon wafers through the existing gas filter. Because of the demanding requirements for the gas, the filter must perform well to guarantee the final product quality.
Since it is crucial to maintain a clean system free of contaminants, it is indispensable to use a gas filter in your semiconductor industry.
Use Gas Filter to Improve Semiconductor Industry
Like any other sintered metal filters, semiconductor gas filters’ regenerative cleaning can be done by physical and chemical methods:
- Clean liquid backwash
- Clean gas backwash
- Ultrasonic method of cleaning
- Dilute acids
- Dilute alkalis
- Enzymes and other cleaning agents
You are recommended to clean your gas filter regularly to keep its effect. The above methods can also be used interchangeably. But remember to choose the proper method according to the actual conditions. If you have any doubt, please contact Filson.
