TRANSISTOR CONTACT AREA ENHANCEMENT

Abstract:

A semiconductor device includes a semiconductor body that includes a surface and a first region and a second region formed in the semiconductor body, where a channel region is located between the first region and the second region, and where the second region includes a sub-region that includes a blanket dopant; a first conductive contact on the surface of the semiconductor body above the first region; a semiconductor-on-insulator (SOI) at a bottom of the first region; and a pocket channel dopant (PCD) formed in the channel, where a first portion of the PCD is adjacent to a first portion of the SOI; and a second conductive contact on a bottom portion of the sub-region, where a first portion of the second conductive contact is adjacent to a second portion of the SOI, and a second portion of the second conductive contact is adjacent to a second portion of the PCD.
