Title: Improvements in or relating to methods of solid state diffusion
IPC: H01L21/00
Filed: 1964-08-24
Abstract: 1,072,322. Semi-conductor devices. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Aug. 24, 1964 [Aug. 27, 1963], No. 34520/64. Heading H1K. In a method of solid-state diffusion a semiconductor body is connected between an inert electrode and an ionic conductor comprising a compound MeX which is provided with an electrode of the metal Me, so that impurities can diffuse between the semi-conductor body and the ionic conductor to vary the impurity concentration of the semi-conductor body. Out diffusion.-As shown, a solid electrochemical circuit 1 comprises an inert electrode 2 of very pure graphite, a semi-conductor body 3 of bismuth telluride containing silver as an impurity, an ionic conductor 4 of silver iodide, and an electrode 5 of silver-tin. The circuit is held together by spring pressure and is heated in an atmosphere of nitrogen. A voltage supply 6 is connected across the electrodes 2, 3 to cause silver atoms to diffuse out of semiconductor body 3 into ionic conductor 4. The ionic conductor may also consist of silver chloride, silver bromide or lead iodide, or may be a mixed crystal, e.g. of silver iodide and lead iodide. A plurality of impurities may be simultaneously removed from a semi-conductor body, for example copper and silver may be diffused out of a germanium body simultaneously using copper iodide for the ionic conductor and copper for the metal electrode. In diffusion.-A semi-conductor body of germanium and an ionic conductor of copper iodide are held between an inert electrode of graphite and an electrode of copper by means of spring pressure and the resulting solid electrochemical circuit is heated in a nitrogen atmosphere. The two electrodes are connected together by an external conductor and a current flows due to the natural E.M.F. of the electrochemical circuit, and copper atoms diffuse from the ionic conductor into the semi-conductor body. A resistor may be connected in series with the circuit to reduce the current flow and thus reduce the diffusion rate. As the impurity concentration of the semi-conductor body increases the natural E.M.F. of the circuit decreases. An external E.M.F. equal to the natural E.M.F. of the circuit at the desired impurity concentration may be connected between the electrodes to "back off" the natural E.M.F. so that when the impurity concentration in the semi-conductor body reaches the selected value the natural and external E.M.F.'s are equal and the diffusion stops. Alternatively an external E.M.F. of opposite polarity may be used to increase the diffusion rate if accurate control of the impurity concentration is unnecessary or if the impurity diffuses very slowly.

Abstract: 1419458 Seismic exploration AMOCO PRODUCTION CO 24 July 1973 [16 Oct 1972] 35255/73 Heading H4D A method of seismic exploration for obtaining a multi-trace record of received seismic signals comprises placing, at each of a set of receiving locations distributed over the exploration region, at least one seismic-wave receiving transducer connected to a nearby digital recorder unit including an adjustable decoder, adjusting the decoders to respond selectively to receipt of respective address codes identifying the receiving locations, and, immediately prior to generating seismic waves, transmitting from a control point to all receiving locations the address codes of only those locations from which a trace is required for inclusion in the record, whereby the relevant decoders respond and activate the associated recorders. In the embodiment described the address codes, followed by "header data" (e.g. relating to seismic source location, recording parameters, date &c.), by a time-break signal and by clock signals, are transmitted from the control point (over wires or by tone-modulation of a radio transmitter) as a string of digital data bits. At the recorders, recognition of an address code results in the associated recorder tape transport being switched on, in the header data being temporarily stored in a buffer register then read-out for recording on tape, then in received seismic signals being recorded digitally on the tape, together with receiver-amplifier gain data, under the control of the clock signals, after which the recorder reverts to a standby state. The invention is applicable to roll-along common-depth-point exploration techniques, the transmitted address codes being changed between one seismic wave generation and another. The resulting tape records may later be re-formatted and computer-processed. Block diagrams are given of circuitry for assembling the data to be transmitted from the control point, and for sorting and transferring the data within a recorder unit.
