SEMICONDUCTOR DEVICE AND METHOD FOR FABRICATING THE SAME, BIPOLAR-CMOS-DMOS AND METHOD FOR FABRICATING THE SAME |
摘要 |
A semiconductor device fabricating method is described. The semiconductor device fabricating method comprises forming an epitaxial layer on a substrate, wherein the epitaxial layer is the same conductive type as the substrate. A first doped region having the different conductive type from the epitaxial layer is formed in the epitaxial layer. An annealing process is performed to diffuse dopants in the first doped region. A second doped region and an adjacent third doped region are formed in the first doped region. The second doped region is a different conductive type from that of the first doped region, and the third doped region is the same conductive type as that of the first doped region. A gate structure is formed on the epitaxial layer covering a portion of the second and the third doped regions.
