VLSI Standards

VLSI Standards is a leading provider of calibration standards and artifacts used to verify the accuracy of metrology instrumentation in high-precision manufacturing environments. The company specializes in producing NIST-traceable standards for particle counting, surface contamination, film thickness, and dimensional metrology. While its primary market is the semiconductor industry, its products are vital for the life sciences sector, particularly in medical device manufacturing and pharmaceutical cleanroom monitoring. Their standards are frequently employed to calibrate equipment used for USP <788> particulate matter testing in injections. Acquired by KLA Corporation in 1998, the company continues to operate as a key supplier of physical reference standards that ensure global manufacturing consistency and regulatory compliance.
