    摘要: A simple process is provided for making a planar CMOS structure wherein isolation regions required by bulk CMOS structures are first formed, an N channel device field region is self-aligned to an N well region in a semiconductor substrate and a refractory material is twice defined for forming P and N channels, the first definition masking P channel source and drain regions while defining the N channel and the second definition defining the P channel while using a photoresist layer to mask the N channel. In the process, a technique which uses a single mask level defines the well region and self-aligns the necessary field doping to the well region to provide closely spaced N and P channel devices.

    摘要: A method for providing self-aligned conductors in vertically integrated semiconductor devices which includes providing recesses in the surface of a semiconductor substrate for the fabrication of V-groove devices, providing a conductive layer over the surface and then applying a layer of masking material over the conductive layer to form a planar upper surface, selectively etching the masking material until it remains only in the recesses and then selectively etching the exposed portion of the conductive layer.
