Title: Manufacture of epitaxial wafer of compound semiconductor
Inventor: NISHINE SHIRO
IPC: H01L21/20
Filed: 1985-09-18
Abstract: PURPOSE:To enable a lattice to be fully matched with a substrate without transition misfitted, by adding a specific amount of homologous elements to the substrate in order to obtain a low transformation density, and then limiting the thickness of an epitaxial growth layer within a specific value in conformity with the added amount. CONSTITUTION:The transformation density in a single-crystal thin film formed by epitaxy, on a semi-insulating substrate 1 comprising III-V compound semiconductor containing a large amount of homologous elements, has close relations with the amount of homologous elements added to the substrate 1 and the thickness of an epitaxial layer 2 formed on the substrate 1. The epitaxial layer is made to grow by monitoring the thickness in conformity with the concentration of the homologous elements in the substrate 1 so that the thickness is made smaller than the thickness expressed in a formula d=0.60 exp (6.4/N) related between the amount N (X10<19>/cm<3>) of the homologous elements added to the substrate 1 and the film thickness d (mum) of the epitaxial layer 2. Hence, the transformation density can be controlled so as to be a low value even if the misfit exists in the substrate 1. Therefore, various kinds of semiconductor devices such as OEIC, FET, HEMT of high performance can be formed with better yield by using a thin wafer of such a low transformation density.

Title: Zinc electrode for alkaline storage battery
Inventor: FURUKAWA SANEHIRO
IPC: C22C18/00
Filed: 1983-10-31
Abstract: PURPOSE:To increase the cycle life of a zinc electrode for an alkaline storage battery by using an indium-thallium-zinc alloy powder as an active material. CONSTITUTION:An indium-thallium-zinc alloy powder is used as an active material. For example, an indium-thallium-zinc alloy powder in which the particle diameter of the metallic zinc powder is restricted to 1-6mu and a zinc oxide powder with particle diameter of 0.1-0.5mu are used as zinc active materials. As a result, indium and thallium adhering to fine zinc particles to form an alloy effectively prevent the fine zinc particles from becoming larger, thereby suppressing the generation of dendrite, increasing the hydrogen overvoltage and suppressing the self discharge. Moreover, indium, thallium and zinc combine together to form a film alloy. Accordingly, there is no possibility that indium or thallium is detached from or separate from the fine zinc particles even during a prolonged period of charge-and-discharge cycles, thereby improving the cycle characteristic.
