Abstract: 1288578 Integrated circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 24 Sept 1969 [27 Sept 1968] 46962/69 Heading H1K All the barrier layers of devices in an integrated circuit consist of insulating layers, Schottky barriers, or junctions between ion implanted regions and a semi-conductor body while all ohmic contacts consist of interfaces between metal and the body material or between metal and ion implanted regions. This enables the circuit to be made using only low temperature processes. One of the devices of the circuit includes a type of barrier layer which is absent from another. The arrangement shown in Fig. 1 consists of an IGFET, with source and drain regions 3, 4 and gold Schottky barrier gate electrode 10, connected by aluminium deposit 11 to a MOSFET with source and drain regions 5, 6 and gate electrode 12. The semi-conductor is a wafer of silicon formed by epitaxial deposition on a substrate which was afterwards etched away electrolytically The wafer is bonded to a Teflon, alumina or beryllia substrate, the oxide layer, thinned at 8 by etching, is deposited from ethoxysilane and the N+ and P+ regions formed by implantation of phosphorus and boron ions respectively. Metal electrodes other than 10 are of aluminium. An alternative circuit also based on an N-type body comprises a PN diode and MOS capacitor with a common contact, the other side of the capacitor being connected to a resistor formed by implantation. In a further arrangement a copper substrate in Schottky barrier contact with the Si body forms the collector of a transistor having an ion implanted junction emitter and a base electrode which also constitutes one electrode of an ion implanted diode. Isolation between devices or groups of devices may be provided by an implanted or metal grid extending the whole or part way through the body and forming a PN or Schottky barrier junction therewith, or by registering grids of Schottky barrier forming metal on opposite faces of the semi-conductor body so biased that their depletion layers meet.

Abstract: 1288598 Modulating light RCA CORPORATION 10 Oct 1969 [16 Oct 1968] 49804/69 Heading B7J [Also in Division H4]  To produce dynamic scattering in a liquid crystal at a rate greater than that obtainable with the minimum electric field Eg necessary to give substantially maximum scattering, and yet to avoid degradation of the crystal by high fields, a field substantially greater than Eg is applied for a fraction of a second (10 ms.) and then decreased to E 0 , e.g. as indicated by the full (D.C.) or dashed (60 Hz) lines in Fig. 2. The time between the leading edge of the turnon pulse and the state of maximum scattering may thus be reduced e.g. from 10 milliseconds to less than 500 microseconds. In Fig. 3 (not shown) wherein the crystal may be used as a light shutter, e.g. in a car or aircraft windscreen, when a photocell detects oncoming headlights or a flare or bomb burst, of above a predetermined light intensity, a trigger circuit is actuated to produce a pulse 50. The pulse is applied to a turn-on circuit, such as shown in Fig. 6, whose output is as shown in Fig. 2, to close the shutter. The trigger may be reset manually, or automatically when the light intensity drops below a fixed level. It is also stated that the trigger may be omitted. In Fig. 6, the pulse 50 is differentiated at 52, 54, 56 to give a waveform similar to that of Fig. 2 which controls the conduction of a transistor 84 of an A.C. voltage from a source 92. The voltage developed across a resistor 90 is applied to a liquid crystal and capacitor in series. In Fig. 4 (not shown), the crystal is placed directly in parallel with the resistor 56 of the differentiating circuit, while in Fig. 5 (not shown), the differentiated pulse controls an FET so as to vary a D.C. field across the crystal.
