AMAT 0110-56802
- Product Name: AMAT 0110 – 56802 Semiconductor Process Gas Filter
- Product Introduction: Process gas purity is of utmost importance in semiconductor manufacturing, as even trace amounts of impurities can affect the quality and performance of semiconductor devices. This gas filter is used to remove particulate matter, moisture, and other contaminants from the process gases before they enter the process chamber.
- Technical Specifications:
- Filtration Rating: Has a specific filtration rating, usually measured in microns or nanometers, indicating the size of the particles it can remove. For example, a filter with a 0.01 – micron rating can remove very fine particles, ensuring high – purity gas supply.

- Flow Capacity: Can handle a certain flow rate of the process gas, typically expressed in standard liters per minute (slm) or standard cubic centimeters per minute (sccm). The flow capacity is designed to match the requirements of the semiconductor process equipment.
- Operating Temperature and Pressure Range: Can operate within a specified temperature and pressure range. For example, it may be able to withstand temperatures from – 20°C to 100°C and pressures from vacuum to several atmospheres, depending on the process conditions.
- Functional Features:
- High – Efficiency Filtration: Uses advanced filtration media, such as membrane filters or depth filters, to achieve high – efficiency removal of contaminants. Membrane filters can provide precise particle removal based on their pore size, while depth filters can trap particles throughout their thickness, offering a large dirt – holding capacity.
- Chemical Compatibility: Made from materials that are chemically compatible with the process gases. For example, for corrosive gases like hydrogen chloride or chlorine, the filter housing and filtration media may be made from Hastelloy or other corrosion – resistant alloys.
- 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 for maintaining the proper gas flow rate and pressure in the process chamber without requiring excessive energy consumption.
- Application Scenarios: Installed in the process gas lines upstream of the semiconductor process chambers. It is used in various processes such as chemical vapor deposition (CVD), where high – purity gases are required for the deposition of thin films with uniform properties. In etching processes, it ensures that the etchant gas is free from contaminants that could affect the etching rate and profile.
