Abstract:
A method of forming a lateral RF MOS device for wireless communications with a non-diffusion source-substrate connection, starting from a substrate, said method comprising the steps of:providing a semiconductor substrate having a principal surface and being of a first conductivity type;growing an epi silicon layer on a top surface of said substrate, said epi layer having a first conductivity type;growing a field oxide layer on a top surface of said epi layer;forming a polysilicon gate;forming a plurality of gate channels;forming a plurality of drain regions and a plurality of source regions;forming a silicided layer on said polysilicon gate; andforming a plurality of metal contacts for connecting said plurality of gate channels, said plurality of drain regions and said plurality of source regions with an outside circuitry;wherein said formation of said silicided layer on said polysilicon gate results in said lateral RF MOS device being utilized for wireless communications.
