| 摘要 |
Disclosed herein is a method of manufacturing a semiconductor device having a thyristor formed by joining a first p-type semiconductor layer, a first n-type semiconductor layer, a second p-type semiconductor layer, and a second n-type semiconductor layer in order, the method including the steps of: forming the second p-type semiconductor layer including a p-type impurity in a surface layer of a semiconductor substrate; forming the first n-type semiconductor layer including an n-type impurity on the semiconductor substrate including the second p-type semiconductor layer by epitaxial growth; forming a non-doped semiconductor layer on the first n-type semiconductor layer by epitaxial growth; and forming the first p-type semiconductor layer including a p-type impurity on the non-doped semiconductor layer by epitaxial growth.
