| 摘要 |
A method of manufacturing a semiconductor device, includes introducing a substrate into a growth furnace, forming impurity absorption layers on the substrate and on inner walls of the growth furnace, the impurity absorption layers absorbing impurities on a surface of the substrate and impurities in the growth furnace, etching and removing the impurity absorption layers and a portion of the substrate to produce a thinned substrate, forming a buffer layer on the thinned substrate, and forming semiconductor layers on the buffer layer.
