Abstract
A semiconductor device including a resistor and a method of forming the same. In the semiconductor device, a conductive pattern, which connects source regions, and a resistor are formed of the same material, which can be polysilicon. In the method, the conductive pattern and the resistor are simultaneously formed. Thus, it is possible to obtain a constant sheet resistance without an additional photo mask.
