Abstract
A multi-cellular power field effect semiconductor device has compact cells including a heavily doped portion of a body region which is self-aligned with respect to an aperture in the gate electrode. The intercept of this heavily doped portion of the body region with the upper surface of the device may also be self-aligned with respect to the aperture and the gate electrode. A method of producing the device is also disclosed.
