Title: Manufacture of gallium arsenide diode emitting infrared rays
Inventor: SHIOSE NOBUYUKI
IPC: H01L21/205
Filed: 1986-02-12
Abstract: PURPOSE:To prevent the decrease in photo taking out efficiency from an upper surface, and realize a Si-doped high efficiency GaAs diode emitting infrared rays, by forming continuously, on a P-type epitaxial layer, a P-type epitaxial layer whose impurity density is lower than that of the former epitaxial layer. CONSTITUTION:In the case where an N-type epitaxial layer and a P-type epitaxial layer are continuously formed on an N-type GaAs substrate, ammonia gas NH3 is introduced as an atmospheric gas during the P-type epitaxy. As the result of introducing the NH3 gas, on a P-type epitaxial layer, a P-type epitaxial layer whose impurity density is smaller than that of the former layer is continuously formed. Thereby, the impurity density and the absoption coefficient of the surface of the P-type epitaxial layer can be made small, so that the decrease of photo taking out efficiency due to the characteristic of the epitaxial layer wherein the impurity density and the absorption coefficient become layer can be prevented.

Abstract: PURPOSE: To obtain a powder cosmetic having excellent extensibility on the skin, capable of hiding pores or fine wrinkles of the skin and improving mainte nance of makeup by including a combination of fine powder and spherical powder at a specific condition. CONSTITUTION: This powder cosmetic contains fine powder having 0.1-2μm voluminous cumulative average granular diameter and <=2 refractive index and spherical powder having 3-50μm voluminous cumulative average granular diameter. The fine powder and the spherical powder are mixed in the cosmetic >=30wt.% in the whole and a mixing weight ratio is 9.5:0.5-0.5:9.5. A part or whole of the spherical powder is stuck to spherical zinc oxide or fine granules of zinc oxide having 15-100m<2> /g specific surface area on the surface. Because the fine powder acts as a light-diffusing component and the spherical powder uniformly adheres to the fine powder, feeling such as slippage on the skin is excellent and unevenness such as pores or fine wrinkles are hidden to give a natural makeup.  Further, this powder cosmetic has an excellent sebum- suppressing effect and instantaneously reacts with the sebum and solidifies, suppresses spread of the sebum, then gives excellent maintenance of makeup and hides unevenness.
