    Abstract: A semiconductor device is provided with semiconducting sidewall spacers used in the formation of source/drain regions. The semiconducting sidewall spacers also reduce the possibility of suicide shorting through shallow source/drain junctions. Embodiments include doping the semiconducting sidewall spacers so that they serve as a source of impurities for forming source/drain extensions during activation annealing.

    Abstract: A method for forming a uniform and reliable oxide layer on the surface of a semiconductor substrate using projection gas immersion laser doping (P-GILD) is provided. A semiconductor substrate is immersed in an oxide enhancing compound containing atmosphere. The oxide enhancing compound containing atmosphere may include phosphorus, arsenic, boron or an equivalent. A 308 nm excimer laser is then applied to a portion of the substrate to induce incorporation of the oxide enhancing compound into a portion of the substrate. The deposition depth is dependent upon the strength of the laser energy directed at the surface of the substrate. A uniform and reliable oxide layer is then formed on the surface of the substrate by heating the substrate. The laser may be applied with a reflective reticle or mask formed on the substrate. An E.sup.2 PROM memory cell having a program junction region in a silicon substrate is also provided. An oxide layer is positioned between a program junction and a floating gate. The oxide layer is formed by a single or multiple thermal oxidation step(s) to have at least a first oxide thickness due to a GILD oxide enhancing compound underlying a region of the oxide having at least the first oxide thickness.

    Abstract: Semiconductor devices comprising a plurality of active device regions formed in a common semiconductor substrate, e.g., CMOS devices, are formed by utilizing shallow trench isolation (STI) technology enhanced by selectively implanting the bottom surface of the trench with dopant diffusion inhibiting ions prior to filling the trench with a dielectric material and formation of opposite conductivity type well regions on either side of the trench. The inventive methodology effectively reduces or substantially eliminates deleterious counterdoping of the subsequently formed well regions resulting from thermally-induced lateral inter-diffusion of p-type and/or n-type dopant impurities used for forming the well regions.

    Abstract: Submicron-dimensioned, silicon-based MOS-type transistor devices having reduced tendency for “latch up” are formed by removing residual indium dopant utilized for forming a retrograde-shaped indium doping concentration profile of the channel region from the surface and uppermost stratum of the silicon substrate by a rapid thermal annealing process prior to silicon oxide thin gate insulator formation.

    Abstract: Submicron-dimensioned MOS and/or CMOS transistors are fabricated by a process employing removable sidewall spacers made of a material, such as UV-nitride, which is readily etched in its as-deposited, undensified state but difficult-to-etch in its thermally annealed, densified state. The as-deposited, undensified spacers are removed by etching with dilute aqueous HF after implantation of heavily-sloped source/drain junction regions but prior to annealing of the implant for dopant diffusion/activation and lattice damage relaxation. Lightly-or moderately doped, shallow-depth source/drain extensions are implanted and annealed after spacer removal.
