IPC: H01L21/8222
Filed: 1965-08-24
Abstract: 1,098,826. Integrated circuits. SONY CORPORATION. Aug. 24. 1965, No. 36298/65. Heading H1K. An integrated circuit comprising for example transistors and resistors, is produced by diffusing an impurity of one conductivity type into a semi-conductor substrate of the opposite conductivity type, epitaxially depositing an intrinsic semi-conductor layer on the substrate and then diffusing some of the substrate and previously diffused impurities into the intrinsic layer to form PN-junctions therein. In the example, a boron doped P-type silicon substrate 20, 250Á thick, is diffused in areas 25a, 25b with phosphorus to produce 8Á N-type regions utilizing photo-resist and oxide masking technique and a 15Á epitaxial silicon layer 23 is deposited over the surface; heating at 1300‹ in wet oxygen for 3 hours causes diffusion of the boron and phosphorous into the overlying intrinsic region. Subsequent diffusion processes are used to provide P-type base zone 26 and N-type emitter zone 28 to form a transistor and P-type zone 30 which constitutes a resistor. The resistor and transistor form part of an integrated circuit and are insulated from each other by PN junctions.

Filed: 1930-12-11
Abstract: 363,503. Valve amplifying circuits. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Dec. 11, 1930, No. 37382. Convention date, Dec. 12, 1929. [Class 40 (v).] In a receiving system for carrier current telegraphy, signal currents are rectified and utilized for the production of impulses, a holding or biasing current, produced by the signal current, being superposed on the amplified impulse currents fed to the receiving relay by grid potential displacement of the impulse amplifier. Incoming currents from the line are passed through a filter s and damping circuit d to correct fluctuation and thence to the high-frequency amplifier v<1>, after which they are rectified by a bridge g of dry rectifiers and pass to the impulse amplifier v2. With this arrangement an impulse is produced at the beginning of each signal element and an oppositely directed impulse at the end, the first switching the relay R on to the working contact and the second on to the cut-out contact. To prevent an accidental or disturbing impulse switching over the relay between the impulses of a signal, a holding current biases the relay and is obtained by superposing the signal potentials from g on a steady biasing voltage from a grid battery GB. The steady anode current is shunted from the relay windings by a bridge arrangement D, r4, r5, v2 which is redrawn as Fig. 2. Alternatively the relay may have an extra compensating winding the magnetizing effect of which opposes the main winding, Fig. 7 (not shown). Instead of a single rectifier arrangement such as g, two sets of rectifiers may be provided, one for the necessary grid bias and the other for passing rectified signals to the impulse amplifier. The two rectifiers may be in parallel across the secondary of transformer u2, Fig. 4 (not shown), or across each half of the centretapped secondary, Fig. 5 (not shown), or u2 may have two separate secondaries each connected to a rectifier set, Fig. 6 (not shown).
