SEMI F43: Particle Contribution Test Method

The SEMI F43 standard is a comprehensive test method designed to assess the particle contribution of Point-of-Use (POU) purifiers and gas filters in high-purity gas distribution systems and semiconductor manufacturing equipment. This method ensures that POU systems meet stringent quality standards, providing reliable performance and maintaining the integrity of critical processes. With its focus on particle generation performance, SEMI F43 is an essential tool for manufacturers and users in the semiconductor industry.

Key Features and Specifications

The SEMI F43 standard is equipped with a condensation nucleus counter (CNC) to accurately measure particulate generation under standardized conditions. This method is applicable to purifiers and filters with flow rates ranging from 0 to 50 standard liters per minute (slm) for purifiers and 0 to 100 slm for filters. The test setup can accommodate various media types and operates at room temperature, making it versatile for different applications. Key features include:

• Accurate particle measurement using condensation nucleus counter (CNC)
• Applicable to various flow rates and media types
• Room temperature operation for versatility

Practical Applications and Benefits

The SEMI F43 standard is invaluable for semiconductor manufacturers looking to qualify POU purifiers and filters for installation in their high-purity gas distribution systems. By ensuring that POU systems meet the highest quality standards, this test method helps to:

• Improve process reliability and reduce downtime
• Enhance product quality by minimizing particle contamination
• Ensure compliance with industry standards and regulations

The SEMI F43 standard is a crucial tool for semiconductor manufacturers and users, providing a reliable and standardized approach to evaluating POU purifiers and filters for optimal performance and process integrity.
