摘要 |
In a semiconductor device manufacturing method, a surface of a substrate structure including a semiconductor layer is covered with a first film including first and second openings. The first opening is configured as an alignment mark. The second opening is configured as an opening for introducing an impurity into a first predetermined position of the semiconductor layer. In this method, a third opening is formed in the first film, using a photo mask aligned with the first opening used as an alignment mark. The third opening is configured as an opening for introducing an impurity into a second predetermined position of the semiconductor layer.
