Title: Semiconductor integrated circuits and method of making the same
IPC: H01L21/20
Filed: 1965-12-01
Abstract: 1,106,197. Semi-conductor devices. DOW CORNING CORPORATION. 1 Dec., 1965 [26 March, 1965], No. 50993/65. Heading H1K. A plurality of isolated silicon islands supported by a thin silicon carbide layer are produced by forming a plurality of mesas in a silicon wafer either by etching or by epitaxial deposition through a mask, depositing the thin supporting layer (substrate) of insulating silicon carbide over the mesas, and removing the opposite face of the silicon wafer to form the islands. Active semi-conductor elements are formed in the isolated islands, and insulating layers, connections and passive elements may be deposited on the surface. The silicon carbide may be deposited by the thermal decomposition of an alkylsilane in a hydrogen carrier gas. Trimethyhlmonochlorosilane, methyltrichlorosilane, propyltrichlorosilane and dimethyldichlorosilane are specifically mentioned as suitable compounds and halogenated and non-halogenated silane and alkylsilane mixtures may also be used. It is stated that dopants may be added to the gas mixture to reduce the resistivity of the deposited layer. The excess silicon may be removed by lapping and polishing or by etching.

Abstract: 1480745 Automatic current regulation RCA CORPORATION 20 Nov 1974 [21 Nov 1973] 53985/73 Heading G3X The total current drawn from a D.C. source by two amplifiers and a storage device is maintained constant by measuring the current flowing in one amplifier and adjusting the currents in the other amplifier and the storage device in correspondence. As shown, a D.C. voltage derived from a horizontal deflection generator 10 in a television receiver is used to supply power to a vertical deflection amplifier including transistors 16, 17 driving a deflection winding 26, a push-pull audio amplifier including transistors 62, 63 connected to a speaker 60, and a storage capacitor 50. The current in the vertical deflection amplifier is measured by sensing the voltage across a resistor 24 and thereby controlling the conduction of transistors 42, 44 in a control network connected between the transistors 62, 63 of the audio amplifier and a summation point C. The current flowing from the point C to ground is maintained constant by the action of resistor 31 and a further transistor 32. The system ensures that the horizontal scan width is unaffected by variations in load taken by circuits powered by voltages derived from the horizontal deflection circuit. The storage capacitor 50 provides quiescent or signal current for the audio amplifer during intervals of peak current consumption by the vertical deflection amplifier.
