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 11):
The method of manufacturing a semiconductor device according to  claim 6 , further comprising:\n forming an extension region including an extension impurity by ion-implanting the extension impurity into the surface layer of the semiconductor substrate by using the gate electrode as a mask, and performing a fourth heat treatment; forming a side wall spacer on a side surface of the gate electrode; and forming a contact region including a contact impurity by implanting the contact impurity into the surface layer of the semiconductor substrate more deeply than the extension impurity by using the gate electrode and the side wall spacer as a mask, and performing a fifth heat treatment on the semiconductor substrate.
