Abstract
Reliable metal oxide semiconductor (MOS) devices which exhibit little or no oxide breakdown at the R edge during device biasing are provided. The improved reliability is obtained by forming a contact to the polysilicon top conductor over a substantially thicker portion of the dielectric region. A method of fabricating the improved CMOS devices is also disclosed herein.
