Abstract: The regulated DC sink is constituted by a current-sensing resistance (RDL), decoupling capacitance (CNF), DC line current detector (ILD) and regulator (ILR), and resistive voltage dividers (R1-R4). A rapid-reaction control amplifier (SRV) drives a current-balancing circuit (SW), depicted as an equiv. controlled resistance and switch, from which the output (AN) is taken to the external load (CL). The decoupling of the latter ensures that the DC characteristic is invariant, while AC supply is used for the shortest possible time.

Abstract: A novel process is provided for fabricating transistors (14), contacts (46s, 40g, 46d) and interconnections (46c) in a novel self-aligned configuration. The process of the invention permits higher packing densities, and allows feature distances to approach 0.5  mu m and lower. In a preferred embodiment, the configuration is also planarized. A unique combination of masks in conjunction with a multi-layer structure (28) formed on the surface of a semiconductor wafer (16), the multi-layer structure including a buried etch-stop layer therein (28b), defines the source (18), gate (22), and drain (20) elements and their geometry relative to each other and to interconnects. Polysilicon plug (40, 46) contacts through slots in the multi-structure layer permit vertical contact to be made to the various elements. Silicidation (56) of the polysilicon plugs reduces series resistance in the vertical direction and permits strapping of N<+> and P<+> polysilicon plugs.

Abstract: For corrosion protection of metallic surfaces in contact with an electrolyte by an external current, using an inert electrode as the external current anode, and a potentiostat, the protective current being periodically switched off and the actual potential (Eact) being measured directly between the external current anode acting in this phase as reference electrode and the surface to be protected and being compared with the protective potential (Eset) set on the potentiostat, and the difference (Eact-Eset) being utilised directly as the control variable for the protective current, it is intended that the protective potential just prevailing at the time is measurable and hence readjustable independently of the protective current which has flowed through. This is achieved when the potential (Eact) is measured after a slight time interval after switching-off and is utilised in the control phase as the control variable for the protective current flowing during the switched-on time. <IMAGE>
