US Patent 10998413 Semiconductor fin structures having silicided portions

The disclosed technology relates generally to integrated circuit structures, and more particularly to a semiconductor fin structure having silicided portions. In an aspect, a semiconductor device including a fin structure and a substrate is disclosed. The fin structure includes a first source/drain region, a second source/drain region, and a channel region. The channel region is arranged between the first source/drain region and the second source/drain region to separate the first source/drain region and the second source/drain region in a length direction of the fin structure. The first source/drain region includes a bottom portion and a top portion, wherein the bottom portion of the first source/drain region is fully silicided and the top portion of the first source/drain region is partly silicided.
