The development of a new silicon-on-glass (SiOG) substrate and device technology is presented. The SiOG material technology consists of anodic bonding and an implant-induced separation to transfer a single crystalline silicon film onto a glass substrate. The silicon-glass interface region is characterized by an ultra-strong and thermally stable bond, and includes an in situ barrier layer that is free of mobile ions. The fabrication and analysis of CMOS devices fabricated on the SiOG substrate are also presented. The SiOG devices are comparable to those fabricated on SOI (SIMOX) wafers with respect to carrier mobility and off-state leakage current. One application for this SiOG technology is the potential integration of high performance circuits and added functionality for mobile display systems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
