Title: Soldered heat-stable polycrystalline diamond product and its production
Inventor: DEBITSUTO AARU SURUZU
IPC: B23K35/32
Filed: 1989-02-20
Abstract: PURPOSE: To braze the molding of self-bonded diamond particles to another similar molding and to join both moldings with high reliability by using a brazing alloy having the liquidus temp. above a specific temp. and contg. an effective amt. of Cr.  
     CONSTITUTION: The porous polycrystalline diamond molding is brazed to another similar molding or cemented carbide support by the brazing alloy consistinig of Ni-Pd-Cr-B, etc., preferably contg. 5 to 20 wt.% Cr. The brazing alloy is required to have the liquidus temp. higher than 700°C. At the time of brazing to the cemented carbide support, heating is executed through the thermally-stable diamond molding while the cemented carbide support is held in contact with a heat radiating element. Consequently, the residual stress which occurs on account of the mismatching of the coefft. of thermal expansion between the carbide and the thermally-stable molding may be averted. The support described above is preferably carbides, such as WC and TiC.

Abstract: PURPOSE:To obtain a fine, fast, lateral, bipolar transistor, by adopting a hetero structure, by using a semiconductor having a large forbidden band energy as a surface protecting film and by preparing a base and an electrode in self- alignment by the use of an electro-transmitter opening part. CONSTITUTION:A high resistance GaAs 1 is coated with no-added Al0.3GA0.7As 2 and SiO2 3. An opening is made in SiO2 3 and a resist 4 is provided to allow a metal layer 50 of Zn/Ni/Au to be deposited in a vacuum. Then, a base electrode metal layer 5 is formed with a lift-off process. SiO2 3 is removed by RIE and then, its layer 5 is coated with SiO2 again. Further, it is treated by RIE and SiO6 remains at side walls. After that, an n-type impurity introduction layer 8 is formed by ion implantation and its layer is annealed. Thus, Zn is diffused from a metallic layer 6 to form a p-type base 9. Then, after vaporizing an electrode metal 10, SiO2 6 is removed by inclined ion-milling and the electrode is completed after heat treatment. Both forbidden band energy and current gain of a layer 2 are so large that the efficiency of ion implantation into an emitter becomes high. As a result, the base 9 together with the electrode 5 is formed in self-alignment and a lateral bipolar device which has a narrow base width and is superior in transport efficiency is obtained.
