Abstract

The invention provides a semiconductor structure comprising a silicon-on-insulator (SOI) substrate, which comprises a silicon layer and an insulating layer stacked from bottom to top, a phosphosilicate glass (PGS) on the insulating layer, and a fluorosilicate glass (FSG) on the phosphosilicate glass. The probability of ions infiltrating into the transistor can be reduced and the yield of products can be improved.
