Abstract: 1486265 Amorphous materials HITACHI Ltd 14 Oct 1974 [17 Oct 1973 22 May 1974] 44449/74 Heading C1A [Also in Division H1] Materials in a true amorphous state (as defined) are produced by irradiating the material with a beam or beams composed of one or more of iron, atoms and molecules in excess of the extent required to convert at least part of the material into a true disordered state (as defined) and then holding the material at a temperature higher than its transition temperature for changing from the true disordered state to a true amorphous state, but lower than its transition temperature for changing from the true amorphous state to a crystalline state. Transition temperatures and ion-beam intensities are listed for elemental (Si, Ge) II-VI and III-V compound semiconductor materials. Exemplified are the formation of true amorphous Ga P, Ga As and CdS. The polished and etched (iii) face of an N-type single crystal Ga P is irradiated (about 25 C) with 200 KeV N<SP>+</SP> ions at an intensity of 5 Î 10<SP>15</SP> cm<SP>-2</SP> and a current density of 1Átcm<SP>-2</SP>. The irradiated sample converted to a true disordered state to a depth of about 0À5 Ám from the surface is heat treated in an Ar atmosphere at 430 C to transform the disordered state to a true amorphous state, the transition being accompanied by a change in the ESR response density and optical transmission properties of the irradiated portion of the sample. Single crystal CdS is irradiated with 300 KeV Cd ions (intensity 10<SP>15</SP> cm<SP>-2</SP>) at a temperature below 80K and then heat treated at 150 K to yield the true amorphous material; an N-type GaAs (Te doped) sample is treated with Ar ions (10<SP>15</SP> cm<SP>-2</SP> intensity) at room temperature and heat treated at 310 C (N 2  atmosphere) to produce the true amorphous state. The true amorphous materials obtained may be used in the manufacture of photocells, photosensors, memory elements and negative resistance elements (see Division H1).

A semi-conductor device is produced by bonding a molybdenum plate provided with a silver layer and over that a gold layer to a goldcontaining electrode on a silicon body by alloying the two gold layers together. An N-conducting silicon body 2 has gold foils 3, 4, containing boron and antimony respectively, alloyed thereto at 700‹ C. to 800‹ C. A molybdenum carrier plate 5 is prepared by providing it with a layer 6 of an alloy of iron, nickel and cobalt on one face and a gold layer 7 on the opposite face. A silver layer 8 is then galvanically applied to the gold layer, or a silver foil is brazed thereto, and a further gold layer 9, less than <SP>1</SP>/ 10  the thickness of electrode 3, is galvanically applied to the silver layer. Molybdenum plate 5 is then arranged with gold layer 9 adjacent electrode 3 and the assembly is heated to about 400‹ to 500‹ C. to alloy layer 9 with electrode 3. A second similarly prepared molybdenum plate 11 is simultaneously bonded to electrode 4. Plate 5 is soldered through layer 6 to a housing 10 and plate 11 is similarly soldered to a copper cup 13 into which a lead wire 18 is pressed. First gold layer 7 may be replaced by a layer of copper or nickel or it may be omitted.
