Abstract: 1530906 Inverting GENERAL ELECTRIC CO 21 Oct 1975 [21 Oct 1974] 43131/75 Heading H2F [Also in Division H3] A switching circuit comprises two seriesconnected controlled switching devices (e.g. transistors Q1, Q3) having means to turn them off simultaneously by removing the control signal from one (a) either by a shunt path bypassing the other or (b) in response to the voltage across an impedance, monitoring current in said devices; and simultaneously increasing the impedance of the other. As described, an inverter comprises a pair of switching devices such as transistors Q1, Q2 arranged alternately to reverse the direction of current from a D.C. source to primary windings W1, W2 of a transformer having an output winding W4 and a tertiary winding W3 coupled to the transsistors Q1, Q2 so that the circuit is self-oscillating. At least one further active element such as transistor Q3 is connected in series with the two switching devices Q1, Q2 and arranged so as to facilitate the turn-off of the two switching devices Ql, Q2. As described, a starting circuit is provided by charging capacitor C2 until Zener diode Q6 breaks down when Q1 and Q3 are turned on so as to build up a current in half of the primary winding W2. Feedback via W3 causes saturation of Q1 and Q3, the current increasing until the transformer approaches saturation. When Q3 comes out of saturation, its collector current is controlled by W3, R3, Q5, connected with Q3 so as to form a current mirror or current inverter. The rising collector voltage of Q3 is monitored by D9 and Q7 and, when it reaches a predetermined value, Q7 is turned on, turning off Q5, Q3 and Q1. Q4 is also turned on so as to discharge the starting capacitor C2 and to connect D8 across Q1 base circuit so as to facilitate turn off. In Fig. 1 (not shown) the emitter currents of Q1, Q2 are monitored by a resistor in the emitter circuit of Q3 which turns on Q5 and Q4. In Fig. 2 (not shown) the emitter current of Q1, Q2 is monitored by a resistor in the collector of Q3. In Fig. 3 (not shown) a separate control transistor is connected in the emitter circuit of Q1 and Q2, each emitter circuit being provided with a separate turn-off arrangement. In Figs. 4 and 6 (not shown) a complementary transistor is arranged as a toggle circuit between the base of each transistor Q1, Q2 and the negative terminal, the toggle circuits controlling a respective twocollector transistor controlling the bases of Q1, Q2 and Q3. Converting.-The inverter may be powered by D.C. obtained from the supply mains, operate a 25 kHz and have a final output rectified to provide a desired value of D.C. voltage output.

Title: Improvements in beam lead semiconductor devices
IPC: H01L21/00
Filed: 1969-08-29
Abstract: 1,270,317. Semi-conductor devices. HITACHI Ltd. 29 Aug., 1969 [4 Sept., 1968], No. 43223/69. Heading H1K. In a beam lead device an insulating layer on the surface of the substrate has a greater thickness at the periphery of the substrate where the layer overhangs the edge beneath the leads. The construction prevents the leads from contacting the edge of the substrate, and strengthens the bond between the leads and the insulating layer. A transistor is produced by selective diffusion into a silicon substrate using an oxide mask (141). Contact windows are exposed and a layer (142) of silcon nitride deposited followed by a layer (171) of silicon dioxide which is processed and used as a mask during the etching of the silicon nitride layer (142) to re-expose the contact windows, Fig. 3(a) (not shown). A thick layer (172) of silicon dioxide is deposited by reduction of SiH 4 , Fig. 3(b) (not shown) and is photomasked and etched to have a ring at what will eventually be the edge of the device Fig. 3(c) (not shown). Metal contacts (15, 16) are deposited by evaporation and comprise successive layers 161, 162 of titanium and platinum with a thick layer 163 of gold or solder forming the beam leads which extend over the thick oxide layer 170 (171, 172), Fig. 3(d) (not shown) and Fig. 2. The semi-conductor material is then etched away from the lower face leaving the leads extending over the edge. The thick layer 170 (171, 173) of silicon dioxide also projects over the edge and is protected during the etching of the silicon by the underlying silicon nitride layer 142. The leads may bridge between separated islands of semi-conductor material containing components.
