Abstract
A semiconductor device is provided which has a power insulated-gate MOS field effect transistor and a control semiconductor element formed in a common semiconductor substrate. A first area corresponding to a drain region of low resistance in the power MOS field effect transistor is different in resistivity than a second area corresponding to the control semiconductor element. The electrical characteristics of each element integrated in the devices is substantially equal to the same element in discrete form.
