  • Liquid phase epitaxial growth method
    Patent number: 4498937
    Abstract: During liquid phase epitaxial growth of a compound semiconductor layer on a substrate, an unsaturated solution is brought into contact with a solute source crystalline plate. The plate dissolves into the solution, which creates a supercooling condition in the solution without a decrease in the temperature of the solution. The crystalline plate has a denser crystal face than that of the substrate, and/or the lattice constant of the crystalline plate is considerably different from that of the substrate.
