SEMI Standards

SEMI International Standards form the foundation for innovation in the microelectronics industry. The SEMI Standards process has been used to create more than 1,000 industry approved standards and guidelines, based on the work of more than 5,000 volunteers in key topics including safety, materials, packaging, traceability and cybersecurity. For 50 years, SEMI standards have helped reduce manufacturing complexity, which enables customer cost reduction, improved supplier quality, and shorter time-to-market. Each year, more than 1,000 companies purchase and use SEMI standards to improve manufacturing operations.
