Abstract: A transistor and method of forming the same are disclosed. A thick mesa of dielectric material is grown on a semiconductor substrate and two or more layers of polycrystalline silicon grown on the vertical sides of the mesa serve a masking function to define the gate region of the transistor with high accuracy. The mesa and the two or more polycrystalline layers remain in the final device.

Abstract: Disclosed is a process for reducing microcracks and microvoids in the formation of polycrystalline (polysilicon) structures from initial layers of amorphous silicon by annealing. In annealing of amorphous silicon to the polycrystalline form, the crystal grains are thickness limited; and thus by maintaining the thickness below 1000 angstroms, the spacing between contrasting material forming the crystal grains can be minimized on anneal. The resultant equiaxial grains are used as seed crystals for epi-like growth of silicon from them into the required or desired layer thickness.

Abstract: A high performance package for integrated circuit semiconductor devices in which decoupling capacitors are provided in close proximity to the integrated circuit devices for reducing voltage variations in the power driver lines, and/or a ground plate overlying the stripe metallurgy on the surface of the substrate for reducing cross-talk between signal lines. The decoupling capacitors are each comprised of a conductive layer on the inside of a via hole, a concentric dielectric layer on the conductive layer, and an electrically conductive plug in physical contact with the dielectric layer that is associated with the driver line circuitry of the package.

Abstract: A substrate article coated with a pinhole free film of silicon nitride produced by reacting silane with a nitrogen containing compound which upon decomposition produces nascent nitrogen and sufficient amounts of a carrier gas that is inert to the reactants and heating said substrate to a temperature above about 500.degree. C to cause the deposition of silicon nitride film on said substrate.
