Abstract: 1,073,599. Semi-conductor devices. TRW SEMICONDUCTORS Inc. Nov. 15, 1965 [Nov. 16, 1964], No. 48475/65. Heading H1K. A thick oxide mask is applied to a semiconductor body by depositing a layer of silver on the areas of the body to be exposed, covering the surface with a thick layer of oxide glass by reactive sputtering in an oxide-rich atmosphere, the silver layer combining with the glass deposited on it, and selectively etching the silvercontaining glass. A plurality of junction diodes are produced in a wafer (10) of N-type silicon by diffusing-in boron to form P-type regions (12), Figs. 1 and 2 (not shown), and forming a layer (15) of silver on each of the P-type regions by chemiplating or electroplating, Fig. 3 (not shown). The wafer is placed on the anode of a reactive sputtering apparatus, Fig. 7 (not shown), which has a cathode coated with silicon and contains an atmosphere of oxygen at a low pressure. A layer (17) of silica is deposited on the surface of the wafer using this apparatus, the silver layers (15) reacting with the ozone produced by the electrical discharge to form silver oxide which combines with the silica to form regions (18) of silver-containing glass, Fig. 4 (not shown). Regions (18) are removed, Fig. 5 (not shown), by immersing the wafer in a selective etchant, such as concentrated nitric acid or a dilute mixture of ammonium fluoride and hydrofluoric acid, and subjecting it to ultrasonic agitation. A layer 20 of gold is deposited in the apertures and over the surface of oxide glass layer 17 by chemiplating, electroplating, or sputtering to form ohmic contacts to regions 12, and the wafer is then diced into individual diodes. The area of the silver layer which enters the glass may be reduced by masking its surface with a dense gold layer.

Abstract: 1,121,477. Transistor switching circuits; pulse modulating circuits. ATOMENERGI A.B. 2 Dec., 1965 [3 Dec., 1964], No. 51273/65. Headings H3T and H4L. In a circuit for switching or chopping a signal appearing between two terminals a and b, of the type in which a first transistor T 1  has its emitter and collector connected to a and b respectively and a second similar transistor has its base and collector connected respectively to a and b and in which the base of T 1  and emitter of T 2  are supplied with equal and opposite control signals in one state of the switch, the control signals are provided by an amplifier or a transformer. It is explained that in the basic circuit the current in T 2  reduces the offset " voltage across T 1  and the currents in the depletion layer capacitances balance out during switching. The amplifier shown, which is of polarity reversing type, may have its input connected to control terminal C and either the emitter of T 2  (as shown) or the base of T 1 . Alternatively, the input and output of the amplifier may respectively comprise (as in Fig. 3, not shown), a bias supply resistor (R 1 , R 2 ) and a transistor (T 4 , T 5 ) shunting the input and output circuits. These transistors are fed with the control signal at their bases and provide a short-circuit to line a-b when the switch is off. A phase-splitting transformer may replace the amplifier (Fig. 4, not shown).
