    摘要: A silicon on insulator fabrication process and structure. The fabrication process includes a reproducible sequence in which an oxide covered substrate is anisotropically etched in the presence of a mask to form trenches which extend into the substrate. Epitaxial silicon is selectively grown in the trench regions in a sucession of first materially doped and thereafter lightly doped layers. The materially doped layer extends above the plane defined by the surface of the substrate. Following a selective removal of the oxide, the materially doped epitaxial layer is exposed at its sidewalls first to an anodization and then to an oxidation ambient. This successive conversion of the materially doped epitaxial layer first to porous silicon and then silicon dioxide dielectric isolates the lightly doped epitaxial layer from the substrate. Planarization of the structure and exposure of the epitaxial surfaces provides electrically isolated islands of monocrystalline silicon for bipolar and field effect device fabrication. A CMOS implementation of the epitaxial islands is readily undertaken by selective counterdoping in the presence of a mask.

    摘要: The invention concerns a BI-CMOS process, in which Field-Effect Transistors (FETs) and Bipolar Junction Transistors (BJTs) are manufactured on a common substrate. In several processing steps, FET structures are formed simultaneously with BJT structures. For example, in one step, polysilicon gate electrodes for the FETs and polysilicon emitters for the BJTs are formed simultaneously. In another aspect of the invention, a polysilicon layer is used to reduce channeling which would otherwise occur during an implant step.

    摘要: A method of planarizing a non-planar substrate, such as filling vias and contact holes, spreads a suspension of a conducting material suspended in a liquid on a substrate. The suspension includes an organometallic material, preferably with particles of a polymerized tin or indium alkoxide. The material is spread by spinning the substrate after applying the suspension. The carrier liquid and organic groups are removed by baking and curing at elevated temperatures, thereby depositing the conductive material on the substrate in a layer which is more planar than the substrate and which has regions of greater and lesser thickness. A relatively brief etch step removes conductive material from regions of lesser thickness, leaving material filling vias or contact holes.

    摘要: An integrated circuit structure and fabrication process for creating field oxide regions having substantially no bird's beak, a relatively planar concluding surface, substantially no stress induced dislocations at the edges of the active regions, and a substantial absence of notches or grooves at the edges of the active silicon, by a selective combination of material dimensions and process operations. In one form of practicing the invention, the process utilizes a relatively thick pad oxide below the masking nitride layer, and a second, very thin, sidewall masking nitride layer. The thin sidewall masking nitride layer does not utilize an underlying pad oxide layer, but may include a thin underlying screening oxide. Upon oxidation, the thin sidewall nitride is concurrently lifted and converted to oxide, the materials and dimension being selected to ensure that when the field oxide level approaches the level of the thick pad oxide layer stresses at the corners of the active silicon region are relieved through various oxide paths and accentuated oxidation effects.
