Title: Vapor epitaxial growth method
Inventor: NAKAMURA MASASHI
IPC: C30B29/40
Filed: 1991-12-05
Abstract: PURPOSE:To reduce a stress, which is remained in a wafer, and to prevent a linear defect from being generated by a method wherein the wafer is split, the split wafer pieces are put in a reaction tube as substrates for growth use and the temperatures of substrate installation parts are controlled in an extent of a specified value to epitaxially grow a III-V compound semiconductor layer. CONSTITUTION:A 2-inch diameter wager cur from an Fe-doped semi-insulating single-crystal InP ingot in (100)-plane is cut along a B-B' line (the direction parallel to an orientation flat) and a C-C' line (the direction to intersect orthogonally the orientation flat) to split into 4. These split wafer pieces are installed on a susceptor 3 of a vapor growth device and an InP layer is epitaxially grown at a growth temperature of 650 deg.C to 700 deg.C by an MOCVD method. In such a way, the areas of the substrates for growth use are made small, whereby a stress which is remained in the wafer can be reduced. Moreover, as the growth temperature is rather high, the residual stress can be released.

Title: Method for preventing oxidation of nitriding layer of extrusion die
Inventor: OHIRA SHIGEO
IPC: B21C29/04
Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To protect a nitriding layer formed on a front face of a die and prevent its peeling, etc., at a pre-heating time by pre-coating with the nitriding layer a boron nitride or an aluminum powder at the time of pre-heating a die made of hot die tool steel formed with the nitriding layer on the front face to a specific temperature in a advance of extruding. SOLUTION: At the time of pre-heating an extruding die to a temperature near the extruding temperature, that is, at the temperature of <=450 deg.C in advance of hot extruding, a nitriding treated face is preliminarily coated with an aluminum or a boron nitride. This aluminum or boron nitride prevents the oxidation and removal of a white layer at the pre-heating time, and a sound hard nitriding layer is kept on the die front face. Especially, in combined coating of the aluminum and the boron nitride, the oxidation of the white layer is restricted effectively even at highly set pre-heating temperature. As a result, the productivity is improved, the wear of a bearing is restricted, the life of the die is prolonged and the extrusion shape steel of high quality is obtained.
