Abstract
In this paper we examine several applications of Rapid Thermal Chemical Vapor Deposition (RTCVD) for the fabrication of sub-100 rum MOSFET’s. Vertical dual-gated MOSFET’s are used as a test vehicle to implement FET’s of very short channel length. To realize such devices, the ability of epitaxial Si1-x-y, GexCy layers for suppressing the thermal diffusion, transient enhanced diffusion, and oxidation enhanced diffusion of boron both in the Si1-x-y, GexCy and in nearby Si layers is very useful Novel gate electrodes deposited by RTCVD also showed the ability to greatly reduce boron penetration in ptype polycrystalline gates for p-channel FET’s.
