Abstract:
To reduce a 1/f noise of an insulated gate field effect transistor. A semiconductor device  1  includes: a well region  5  provided on a surface layer of a semiconductor substrate  2 ; a source region  14 S and a drain region  15 D disposed to be distant from each other on the surface layer of the well region  5 ; a channel region  6  provided between the source region  14 S and the drain region  15 D; and a gate electrode  8  provided over the channel region  6  with a gate insulator  7  interposed therebetween. A gate length of the gate electrode  8  is 1.5 μm or less, the channel region  6  includes indium as a channel impurity, a distance between a surface of the channel region  6  and a concentration peak position of the channel impurity is 20 nm to 70 nm, and a concentration of the channel impurity gradually decreases in a direction from the concentration peak position of the channel impurity to the surface of the channel region.

Claim (Index 9):
The semiconductor device according to  claim 2 , further comprising:\n a side wall spacer provided on a side surface of the gate electrode; and a silicide layer provided on a surface of each of the gate electrode, the source region, and the drain region.
