Abstract: 967,365. Semi-conductor solid circuits. WESTINGHOUSE ELECTRIC CORPORATION. May 12, 1961 [July 29, 1960], No. 17403/61. Heading H1K. [Also in Division H3] A solid circuit comprises a semiconductor body including zones of different conductivity types forming at least two semi-conductor device configurations which are electrically isolated within the body by high resistivity or intrinsic regions. A two-stage amplifier, the circuit of which is shown in Fig. 1, may be formed in a single crystal wafer of 100-200 ohm cm. N-type silicon of dimensions 250x 150 x 4 mils by the following steps. A well is first etched in the lower surface of the wafer, which may be a dendritic crystal, and phosphorus diffused into the entire surface to form an N layer 0.5-1 mil. thick. After removing the layer from all but the bottom face, gallium is diffused into the entire surface to form a P layer 44 (Fig. 2) on the upper surface, the lower surface 46 remaining N-type due to the high surface concentration of phosphorus. The whole surface is next oxidized and photo-resist and etching techniques used to expose parts into which phosphorus is then diffused to form N layers 53, 56, 0.3 mils. thick. Photo-resist and etching techniques are again used to form grooves 53 in the surface to isolate various parts of regions 44, 46. After reoxidizing the surface and etching to leave oxide only at 61a, 62a, the surface is again oxidized, contact areas 52, 55a, 56a, 57, 58 and 62-64 are exposed by photo-resist ande tching techniques, and aluminium deposited to form the contacts. Contacts are similarly formed on the lower surface of the wafer (Fig. 4). After passing heavy current pulses between layers 63, 64 and electrode 65 to form low resistance current paths between them gold wires 15, 16, 17, 19 are bonded to the contacts as shown. Parts 67, 68 of the N-type layer form resistors 34, 36 (Fig. 1) respectively, 65 overlies a collector zone common to the two transistors, the emitters of which are 55, 56, and the PN junction between electrodes 52, 56 forms capacitor 30. In an alternative manufacturing method gallium is first diffused into the entire surface, and the resulting P layer removed except from the upper face. The well is then formed in the lower surface as before. Gold-antimony foils are alloyed to the wafer to form N-type emitter regions 59, 60 with overlying electrodes 55a, 56a, N-type collector regions and overlying electrodes 65, 66 and ohmic contacts 63, 64. Foils of gold-boron are simultaneously alloyed to the wafer to form ohmic contacts 52, 57, 58, 63 and 64. After forming low resistance paths between contacts 63, 64 and 65 as before, the grooves 53 are etched and gold wires 15, 16, 17, 19 and 61, 62 bonded to the wafer to form the external and internal connections. A modification of this unitary structure including a narrow band filter for tuning is also described. Specification 882,974 and U.S.A. Specification 2,663,806 are referred to.

Title: Improvements in or relating to sound-boards for musical instruments
IPC: G10C3/06
Filed: 1921-06-27
Abstract: 185,553. Grotrian, Helfferich, Schulz, T. Steinweg Nachfolger, and Hansen, C. J. June 27, 1921. Sound-boards for musical instruments are composed of woods selected in various ways according to the products of their elasticities and specific gravities. These products may be kept constant with both the elasticities and the specific gravities constant or not. The products may be greater for the treble than the bass, or may rise in stages towards the middle and then fall. In the latter case the ratios of the elasticities to the specific gravities may remain equal or vary uniformly. Where the products are too high or too low, the woods may be utilized by reducing or increasing the thickness or width by one-quarter of the percentage excess or deficiency, different thicknesses being made to merge. The invention is also applicable to parts of the sound-board, as the ribs.
