| Zusammenfassung: | A method of manufacturing a semiconductor device includes: forming, on a surface of an n-type semiconductor layer, an impurity source film containing both aluminum and beryllium; and forming a p-type impurity-doped layer in the n-type semiconductor layer by irradiating the impurity source film with first laser light to simultaneously introduce the aluminum and the beryllium into the n-type semiconductor layer. |
