AMAT 0021-39721
- Product Name: AMAT 0021 – 39721 Semiconductor Process Gas Filter
- Product Introduction: This gas filter is an essential component in semiconductor process gas delivery systems. Semiconductor manufacturing processes rely on the use of high – purity gases for various operations such as deposition, etching, and doping. The filter is designed to remove particulate contaminants, moisture, and other impurities from the process gases to ensure the quality and reliability of the semiconductor devices being produced.
- Technical Specifications:
- Filtration Rating: Has a high filtration rating, typically in the range of sub – micrometers. For example,

- it may be able to filter out particles as small as 0.003 micrometers to meet the stringent purity requirements of semiconductor processes.
- Flow Capacity: Can handle a specific range of gas flow rates, depending on the process requirements. The flow capacity is designed to ensure that the gas supply to the process chamber is sufficient while maintaining the filtration effectiveness. It can range from a few standard cubic centimeters per minute (sccm) to several thousand standard cubic feet per hour (scfh).
- Material Construction: Made from materials that are compatible with the process gases and can withstand the operating conditions. Common materials include stainless steel for the filter housing and high – efficiency filter media such as PTFE (polytetrafluoroethylene) membranes or sintered metal filters.
- Functional Features:
- High – Efficiency Filtration: Utilizes advanced filter media and design to achieve high – efficiency particulate removal. The filter media may have a large surface area and a fine pore structure to trap even the smallest particles.
- Chemical Resistance: Resistant to corrosion from the process gases, which may include reactive gases such as hydrogen chloride, ammonia, or silane. This ensures the long – term stability and reliability of the filter in the semiconductor manufacturing environment.
- Low Pressure Drop: Designed to have a low pressure drop across the filter, which means that it does not significantly impede the flow of the process gas. This is important to maintain the proper gas flow and pressure conditions within the process chamber.
- Application Scenasons: Installed in the process gas lines of semiconductor fabs, upstream of the process chambers. It is used in various processes such as chemical vapor deposition (CVD), where high – purity gases are required to deposit thin films on the wafer surface, and in etching processes to ensure clean and precise removal of material from the wafer.
