Abstract
Provided is an epitaxial growth method for forming a high-quality crystalline growth semiconductor wafer. The method includes forming a buffer layer on a single crystalline wafer using a single crystalline material; forming a mask layer on the buffer layer; forming a plurality of holes in the mask layer using a laser to expose portions of the buffer layer; forming wells having a predetermined depth in the exposed portions of the buffer layer by injecting an etchant into the holes; removing the mask layer and annealing the buffer layer to form a porous buffer layer having cavities obtained by the wells; and forming a crystalline material layer on the porous buffer layer using an epitaxial growth process.
