Abstract
1,239,560. Crystallizing. WESTERN ELECTRIC CO. Inc. 20 Sept., 1968 [21 Sept., 1967], No. 44816/68. Heading B1S. A whisker having a narrow tip is grown on a wafer of the same material from a liquid alloy zone into which supply material is absorbed from the vapour state and from which the alloy-forming agent is progressively removed by (a) evaporation, (b) incorporation in the whisker, (c) formation of a gas by a chemical reaction, or (d) conversion into supply material by a chemical reaction. The agent may be placed on the wafer at one or more sites manually; or by evaporation or electroplating, using a mask to form a pattern if desired. It may be Au, Sn, Cu, or Ga. The absorbed supply material may be condensed from its vapour or formed by a chemical reaction. It may be Cu, Si, SiC, or GaAs. A silicon whisker may have a length of 1 mm and a tip with a radius of curvature less than 1 micron.
