Abstract
In this paper, arsenic and boron redistributions in the SiO2 /WSi2 /Si structure are well characterized and successfully modeled. The solubility of arsenic in WSi2 at different temperatures plays an important role in determining how As redistributes. Arsenic pile-up at the SiO2 /WSi2 interface and segregation at the WSi2 /Si interface are also investigated. The fast segregation and growth of the precipitate of boron atoms at the SiO2 /WSi2 interface are the key factors in modeling boron redistribution. A novel method is introduced to simulate dopant growth at the interfaces and is implemented in the SUPREM III program.
