    Abstract: A method for forming a planar insulating layer over the surface of a semiconductor workpiece 8 which includes at least one low region 13 is discussed herein. The first step is to form a layer of blocking material 14 on the surface of the workpiece 8. A first material region 20 is then formed in the low region 13 and an insulating layer 21 is formed over the surface of the workpiece 8 including the first material region 20. The workpiece 8 is then heated in the presence of an active ambient such that the insulation layer 21 reflows and also so that the first material 20 region reacts with the active ambient to create an internal stress in said insulation layer 21. Other systems and methods are also disclosed.

    Abstract: A semiconductor device includes a semiconductor substrate of a first conductivity type, in which a drain region is formed in the substrate, and a gate electrode is formed on the surface of the substrate via an insulating film formed thereon. A Schottky metal as a source region is formed in the surface of the substrate away from the drain region, the Schottky metal and the substrate constituting a Schottky junction at an interface therebetween near the gate electrode. A shield layer of a second conductivity type is interposed between the Schottky metal and the substrate except in the Schottky junction. The gate electrode controls tunnel current at the Schottky junction.

    Abstract: A reduced area butting contact structure (10') is provided, which is especially suited for four-transistor static RAM cells. A structure is formed which includes a doped silicon region and one or more layers of polysilicon and oxide situated thereabove, one of which layers of polysilicon may be a gate polysilicon. An anisotropic etch is then performed through all upper layers including any upper polysilicon layers which may be present, but stopping at the doped silicon region and any gate polysilicon layers present, to form a contact hole (26'). The contact hole is filled with a conductive plug (32) of a material such as tungsten or polysilicon and etched back. In either case, contact with all polysilicon layers present and the doped silicon region is made. In the anisotropic etching process, a two-step etch is employed. The first etch is non-specific as to material, etching all relevant materials (polysilicon and oxide) at substantially the same rate and is continued through any upper polysilicon layers, but is terminated prior to etching the doped silicon region or any gate polysilicon layers (22). The second etch is specific as to material, etching silicon dioxide faster than polysilicon or silicon, and thus stops at the gate polysilicon layer and the doped silicon region.

    Abstract: A fusible link structure and method of making the same for use in integrated circuit structures is provided in which the fusible link comprises, in one embodiment, an alloy of platinum and silicon. The preferred alloy comprises the eutectic mixture having approximately 23 atomic percent silicon. Electrical connections to the fusible link are preferably provided by a layer of aluminum on a layer of material, preferably an alloy of titanium and tungsten wherein the titanium and tungsten alloy is disposed between the fusible link and the aluminum layer, and serves as a diffusion barrier for preventing diffusion of the aluminum into the fusible link. In a preferred embodiment, a fusible link is deposited on a relatively thick dielectric layer, preferably more than 10,000 .ANG. thick, having a relatively low thermal conductivity. The preferred method of depositing the fusible link is sputtering from a target comprising the platinum-silicide alloy, thus achieving a fuse element having uniform composition throughout its cross section. A fuse of this type has high reliability, requires low fusing current, and is dielectrically encapsulated sealed within the integrated circuit structure.

    Abstract: A semiconductor device has a surface zone which forms a planar pn junction with the surrounding substrate, this pn junction being biased in operation in the reverse direction. In order to increase the breakdown voltage, one or more floating zones are located beside the pn junction within the range of the depletion zone, which also form planar pn junctions with the substrate. According to the invention, the floating zones have an overall doping of at least 3.multidot.10.sup.11 and at most 5.multidot.10.sup.12 atoms/cm.sup.2, as a result of which they are substantially depleted at a high reverse voltage.
