Patent ID: 7014711

Claim:
A liquid-phase growth apparatus for growing a crystal on a substrate, comprising: a crucible containing a solution that contains a raw material for forming the crystal; and a substrate holder including: a connectors; and a receiving component and push component which are opposite to each other and are connected by the connectors, the substrate holder vertically holding the substrate, the push component holding an upper portion of the substrate, the receiving component holding a lower portion of the substrate, wherein the receiving component has a V groove at a surface opposite to the push component, and the push component has an inverted V groove at a surface opposite to the receiving component, the V groove facing the inverted V groove, the receiving component holding a lower edge of the substrate while the push component holds an upper edge of the substrate, wherein the receiving component is loosely connected to the push component with the connectors so as to be vertically movable so that the receiving component comes down by the own weight when the substrate holder is not dipped in the solution and comes up by buoyancy thereof when the substrate holder is dipped in the solution.
