Title: Methods of treating bodies of gallium arsenide
IPC: H01L21/00
Filed: 1961-02-21
Abstract: 954,577. Semi-conductor devices. WESTERN ELECTRIC CO. Inc. Feb. 21, 1961 [Feb. 26, 1960], No. 6282/61. Heading H1K. A solid body of gallium arsenide is heated in the presence of a gaseous compound of germanium, silicon or tin to alter the conductivity or conductivity type of at least part of the body. Suitable gaseous compounds are silicon dichloride or tetrachloride, silicon difluoride or tetrafluoride, silane, disilane, and the tetrachlorides of germanium and tin. Apparatus used in the process is preferably made of alumina or molybdenum. Silica is unsuitable because it reacts with the gaseous compounds at the temperatures involved. In one method 5 ohm cm. P-type monocrystalline gallium arsenide slices 16 (Fig. 1) and silicon tetrachloride 13 are sealed into opposite ends of tube 10. After placing the end 12 of the tube in a mixture of acetone and dry ice at - 56 C. and allowing 2 minutes to attain equilibrium the narrow part 11 of the tube broken and part 15 is sealed off with silicon tetrachloride at a partial pressure of 8 mm. of mercury therein. The tube is then heated for 24 hours to 820 C. or 1100 C. to produce an N-type layer on the slices 2Á or 1 mil. thick respectively. Alternatively in a continuous flow method slices 26 (Fig. 2) of P-type gallium arsenide are placed after etching and polishing in tube 20 as shown. After raising the assembly to 600-1200 C. the tube is flushed with helium or nitrogen and then a mixture containing 2 vols. silicon tetrachloride to 100 vols. of helium is flowed through the tube for from 1 hour to several days. The resulting N layer may be selectively removed from the bodies to give the required device configurations. Use of the process to give low resistivity contact surfaces on N-type bodies is also suggested.

Abstract: 1425143 Aerials; radio navigation HAZELTINE CORP 13 Feb 1974 [3 April 1973] 6506/74 Headings H4A and H4D An aerial system radiates into a spatial region during a selected time period so that the frequency in said region varies with a component of angular direction from said system. It comprises an aerial unit capable of radiating a plurality of beams in said region of space from a common aperture, said unit having a respective input port corresponding to each beam. It also comprises means for supplying a simultaneously respective input signals to said ports during said time period, each of said signals having a phase, measured with respect to a reference phase, which varies during said time period between a predetermined pair of values that is unique with respect to the pair associated with any other of said signals. In a first embodiment an aerial unit of the kind described in Specification 1,425,142 comprises a parabolic reflector 11, Fig. 1, and feedhorns 10a, 10b, 10c in the vicinity of a particular point on the focal axis of said reflector. Each feedhorn, when energized, sets up a planar beam in space which has a characteristic angle in a plane which is perpendicular to the focal axis. An oscillator 15 supplies a power divider 16, which feeds the input ports 12a, 12b, 12c of the horns 10a, 10b, 10c through respective variable phase shifters 14a, 14b, 14c. As is shown in Fig. 2, the phase shifter 14c is maintained at reference phase, whilst each of the phase shifters 14a, 14b is varied linearly during successive periods of time from reference phase minus a certain value to reference phase plus that value, said values being different for each phase shifter. The phase variations need not be linear, and they may be effected at an intermediate frequency. In a second embodiment, the multiple beams are generated by means of an aerial array which is fed from the output ports of a Butler matrix (Fig. 4, not shown). Each input port, corresponding to a particular beam, is supplied through a respective variable phase shifter, as in the first embodiment.
