    摘要: This invention is a technique for forming a specifically configured region of material which is rejected by an advancing freezing front within a melt. Resolidification of the molten material is effected in such a manner that liquid-solid interfaces intersect so as to control the shape and location of the rejected material which solidifies. Specific embodiments involve the formation of wires, tubes, or planes of enriched rejected material. Applications include the formation of enriched conductive material for making electrical contact between internal or external regions of electronic devices. Additionally, enriched material with etching properties different than that of the surrounding material may be formed and subsequently etched away in micro-machining applications.

    摘要: Cylindrical ingots of materials that expand on melting or freezing are purified or zone refined by a process which includes providing a tubular container having both a cylindrical cavity and a slot along its entire length. In zone refining, as is well-known, a heater of a predetermined elevated temperature traverses from one end of a normally solid charge to another at least once to thereby sweep impurities to one end of the charge. During the zone refining process, material which expands on phase change (e.g., solid to liquid) flows into the slot. As a consequence, fractures and other damage to the container and/or zone-refined material are minimized. The substantially round cross section is retained following removal of the excess material from the zone refined ingot after solidification.

    摘要: Apparatus and method for stabilizing and supporting a crystal semiconductor rod during fabrication refining from the action of a seed rod on a float zone melt of a crystalline rod source is provided wherein engageable fingers mounted in a vertically movable tube in axial register with the shaft holding the crystal seed rod are pivotally mounted in a non-horizontal upward position, the finger tips being force loaded for inward movement upon removal of a sleeve carrier so that the fingers engage, support, and stabilize the irregular cylindrical surface of the refined semiconductor rod. The tube and fingers are engageable through sleeve and tube piston means resulting in uniform stabilization and support of the crystal refined rod. The apparatus and method prevent the refined rod from vibrating and oscillating about its axis; thus allowing enlarged dislocation free crystal rod growth from a crystalline rod source, said refined crystal rod being grown on a slender seed rod.

    摘要: An improved method of initiating the moving of a molten zone of an aluminum rich semiconductor material through a solid body of the same semiconductor material to form a planar region embodies alloying the aluminum metal to the semiconductor material of the surface of the body in contact therewith at a temperature of from 577.degree. to 660.degree. C. The alloying process enables one to migrate two or more intersecting "wires" simultaneously, as well as three "wires" intersecting at a common point of origin, through the body.

    摘要: A method for producing a unique InSb thin film element which comprises the steps of forming a thin film of InSb polycrystal on a substrate of insulating material, forming an oxide film on the InSb thin film, zone-melting the InSb thin film by heating the thin film covered with the oxide film to a temperature above the melting point of InSb in a controlled gaseous heat-treating atmosphere comprising an inert gas containing from 1 ppm to 3 .times. 10.sup.4 ppm of oxygen, which is replaceable by an addition of a tenfold amount of aqueous vapor to the extent of 10.sup.2 ppm of oxygen, and cooling the resultant element. An InSb thin film element produced in this way is suitable as a material for a magnetosensitive element of good performance, especially a low noise level or a high S/N ratio.
