Abstract

A semiconductor device includes a semiconductor substrate, and a first transistor. The first transistor has a first gate on the semiconductor substrate, and a first lightly doped source/drain region within the semiconductor substrate to determine a first channel region beneath the first gate. A doping ratio determined as a concentration of the first lightly doped source/drain region divided by a concentration of the first channel region ranges from 1.0×10to 1.0×10.
