| Zusammenfassung: | A method of manufacturing a semiconductor device including the steps of providing a substrate having first type semiconductor regions and second type semiconductor regions, forming a conformal first epitaxy mask layer on the substrate, forming first type epitaxial layer in the substrate of the first type semiconductor regions, forming a conformal second epitaxy mask layer on the substrate, forming second type epitaxial layer in the substrate of the second type semiconductor regions, and removing the second epitaxy mask layer. |
