Abstract:
A semiconductor device and its manufacturing method, relating to semiconductor techniques. The semiconductor device manufacturing method comprises: forming a patterned first hard mask layer on a substrate to define a position for buried layers; conducting a first ion implantation using the first hard mask layer as a mask to form a first buried layer and a second buried layer both having a first conductive type and separated from each other at two sides of the first hard mask layer in the substrate; conducting a second ion implantation to form a separation region with a second conductive type opposite to the first conductive type in the substrate between the first and the second buried layers; removing the first hard mask layer; and forming a semiconductor layer on the substrate. This inventive concept reduces an area budget of a substrate and simplifies the manufacturing process.

Claim (Index 7):
The method of  claim 6 , wherein forming a first connection component and a second connection component comprises:\n forming a patterned second hard mask layer on the semiconductor layer, with the second hard mask layer having a first opening and a second opening each exposing a portion of the semiconductor layer; conducting a third ion implantation to dope the portion of the semiconductor layer underneath the first opening and the second opening to form the first connection component and the second connection component, respectively; and removing the second hard mask layer.
