Abstract
A MOS-gated semiconductor device may be manufactured by a process in which the neck region of the device is doped through a previously deposited polysilicon gate. In the method of the present invention, the dopant in the neck region of the device is not subjected to the same temperature history as the body dopant, thereby providing means to increase the ruggedness of the device and providing means by which the threshold voltage of the device may be controlled.
