SEMI Standards for SiC Wafers

Abstract

SEMI Standards charter is to develop standards that benefit the semiconductor industry. The SEMI organization has evolved over the last 40 years into an international organization with covering all aspects of semiconductor and flat panel materials and devices. SEMI Standards provides the framework for the development of consensus based standards documents. At present there are two published standards specific to silicon carbide, the first dealing with dimensions, properties and ordering information for SiC wafers, and the second defining a nomenclature for defects found on SiC: SEMI M55-0817 Specification for Polished Monocrystalline Silicon Carbide Wafers SEMI M81-0611 Guide to Defects Found on Monocrystalline Silicon Carbide Substrates Additional standards applicable to various semiconductor wafers also are available and new SiC related standards are being developed based on industry needs and volunteer participation.
