Abstract: A method and structure for forming a modified field oxide region having increased field oxide threshold voltages (Vth) and/or reduced leakage currents between adjacent device areas is achieved. The method involves forming a field oxide using the conventional local oxidation of silicon (LOCOS) using a patterned silicon nitride layer as a barrier to oxidation. After forming the LOCOS field oxide by thermal oxidation and removing the silicon nitride, a conformal insulating layer composed of silicon oxide is deposited and anisotropically etched back to form sidewall insulating portions over the bird's beak on the edge of the LOCOS field oxide, thereby forming a new modified field oxide. P-channel implants are formed in the device areas. Then a second implant is used to implant through the modified field oxide to provide channel-stop regions with modified profiles that increase the field oxide Vth and/or reduce leakage current between device areas.

Abstract: A CMOS device structure, and a method of fabricating the CMOS device, featuring a gate insulator layer comprised of a high k metal oxide layer, has been developed. The process features formation of recessed, heavily doped source/drain regions, and of vertical, polysilicon LDD spacers, prior to deposition of the high k metal oxide layer. Removal of a silicon nitride shape, previously used as a mask for definition of the recessed regions, which in turn are used for accommodation of the heavily doped source/drain regions, provides the space to be occupied by the high k metal oxide layer. The integrity of the high k, gate insulator layer, butted by the vertical polysilicon spacers, and overlying a channel region provided by the non-recessed portion of the semiconductor substrate, is preserved via delayed deposition of the metal oxide layer, performed after high temperature anneals such as the activation anneal for heavily doped source/drain regions, as well as the anneal used for metal silicide formation.
