Abstract:
An object of the present invention is to provide a semiconductor device and a manufacturing method thereof that may achieve low power consumption in a digital circuit and reduce influence of noise in an analog circuit. The manufacturing method of the semiconductor device includes a first source/drain forming step of forming a first source region and a first drain region by implanting impurities of a second conductivity type into a digital side second conductivity type impurity layer using a gate electrode and a sidewall as a mask and a second drain/source forming step of forming a second source region and a second drain region by implanting impurities of the second conductivity type into an analog side second conductivity type impurity layer using a gate electrode and a sidewall as a mask more shallowly than the impurities of the second conductivity type implanted in the first source/drain forming step.

Claim (Index 7):
The manufacturing method of the semiconductor device according to  claim 1 , wherein\n in the forming the second well layer, the impurities of the first conductivity type are implanted so that concentration of the impurities of the first conductivity type increases in a depth direction of the semiconductor substrate.
