    摘要: A process for the formation of a device edge morphological structure for protecting and sealing peripherally an electronic circuit integrated in a major surface of a substrate of semiconductor material. The electronic circuit is of the type that calls for formation above the major surface of at least one dielectric multilayer. The dielectric multilayer includes a layer of amorphous planarizing material having a continuous portion extending between two contiguous areas with a more internal first area and a more external second area in the morphological structure. The device edge morphological structure includes in the substrate an excavation on the side of the major surface at the more internal first area of the morphological structure in a zone in which is present the continuous portion of the dielectric multilayer.

    摘要: A nonvolatile memory having a cell comprising an N.sup.+ type source region and drain region embedded in a P.sup.- type substrate and surrounded by respective P-pockets. The drain and source P-pockets are formed in two different high-angle boron implantation steps designed to optimize implantation energy and dosage for ensuring scalability of the cell and avoiding impairment of the snap-back voltage. The resulting cell also presents a higher breakdown voltage as compared with known cells.
