Title: Method of fabricating semiconductor devices
IPC: H01L29/00
Filed: 1971-06-17
Abstract: 1326997 Semi-conductor devices R C A CORPORATION 17 June 1971 [30 Sept 1970] 28514/71 Heading H1K In a method of fabricating an IC an opening is provided in a thermally grown layer of SiO 2  by a process resulting in a structure the parts of which are non-decomposable at an elevated temperature and then within a preset short period of time of exposure to an uncontrolled oxidizing atmosphere, heating the body in a controlled oxidizing atmosphere to grow a second layer of SiO 2  on the exposed parts of the substrate. A plurality of storage type IGFETs are produced by diffusing source and drain regions into a Si layer, thermally growing a thick SiO 2  layer and deposiiting a layer of Si 3 N 4  and then a further layer of SiO 2 . A photoresist mask is used to etch apertures corresponding to the gate areas in the top SiO 2  layer and this layer is used as a mask for the etching of the Si 3 N 3  layer. Alternatively the top SiO 2  layer may be omitted and the Si 3 N 4  layer etched directly using a photoresist. Any remaining photoresist is then removed and the final etching of the thick SiO 2  layer performed using the Si 3 N 4  layer as a mask so that the resulting structure may be transferred directly to a furnace for the growth of a thin gate oxide layer under controlled conditions. Exposure to the ambient air should be for less than a prescribed time e.g. 2 minutes, to reduce the effect on the final thickness of the gate oxide of the formation of spontaneous oxide layers. A layer of Si 3 N 4  is then formed on the thin gate oxide, windows are opened to expose the source and drain regions, and a layer of metal is deposited and defined to form the source, drain and gate electrodes. The gate electrode may be of Al or heavily doped Si. The mask used to etch the thick SiO 2  may also be of Al 2 O 3 . In an alternative embodiment a layer of SiO 2  thicker than is required in the final device is grown and depressions or wells are etched above the channel regions using a photoresist. The photoresist is then removed and the whole SiO 2  layer is etched to extend the depressions until the surface of the Si is exposed, the thickness of the surrounding SiO 2  also being reduced to the final value. The wafer is then transfered to the furnace to grow the thin gate oxide layer.

A spray transfer arc-welding system provides means for varying the current magnitude or rate of change of current in the arc-welding and/or short-circuit spray transfer states. In a simple arrangement a resistor may be shortcircuited after a time delay determined by the onset of the short-circuit condition, or another supply may be switched in parallel. Alternatively the arc current may be supplied through an A.C. flux reset transductor controlled rectifier arrangement in which magnetic saturation of the cores due to increased load current increases the short-circuit current. The arc current may have a level or drooping characteristic determined by a feedback winding. The system may be fed from a single or 3-phase supply. In another arrangement, the transductor is controlled by arc voltage drop.
