Title: Zinc selenide single-crystal film
Inventor: OGAWA HARUKI
IPC: C30B29/48
Filed: 1986-06-19
Abstract: PURPOSE:to reduce diffusion of impurities from a substrate, by providing a ZnSe layer or a specific InGaAs layer on a GaAs substrate, forming thereon a multiplicity of InGaAs layers having different GaAs molecular composing ratios in an altenate manner to provide a multilayer film and further providing a ZnSe layer thereon. CONSTITUTION:On a GaAs substrate 6, there is formed a ZnSe layer or an In1-xGaxAs layer (x represents a molecular composing ratio of GaAs) approximately matched in lattice with ZnSe. A multiplicity of In1-xGaxAs layers having a smaller lattice constant than that of ZnSe and In1-xGaxAs layers having a larger lattice constant than that of ZnSe are alternately formed thereon so as to provide a multilayer film (an average lattice constant of this multilayer film is approximately equal to that of ZnSe). Further, a ZnSe layer is formed thereon. In this manner, a ZnSe single-crystal film can be obtained without any effect of misfit transformation due to mismatching in lattice (difference in lattice constant) with the GaAs substrate and diffusion of impurities from the substrate can be reduced. Thus, the obtained ZnSe single-crystal film is allowed to have high crystallinity.

Filed: 1978-11-15
Abstract: PURPOSE: To obtain a self-curing solid resol resin of constant quality readily, by incorporating a novolak resin into a dehydrated and concentrated revol resin, which is the reaction product of a phesol with formaldehyde.  
     CONSTITUTION: A phenol (p) is condensed with formaldehyde (F) in the presence of an alkali catalyst or a neutral salt at a molar ratio of (F) to (P) of 1.5W2.5:1 to give a resol resin having a suitable molecular weight, which is dehydrated and concentrated in vacuo. At the resol resin temperature of 90W110°C, a novolak resin having a softening point ≥110°C is incorporated into the resin, and the mixture is cooled to form a self-curing solid resol resin composition. If the resin temperature is below 90°C, the dehydration is insufficient. If the temperature exceeds 110°C, the curing tends to proceed.
