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 18):
A semiconductor device, comprising:\n a substrate, comprising:\n a first buried layer and a second buried layer separated from each other in the substrate, wherein the first and the second buried layers both have a first conductive type and both comprise a first dopant and a second dopant, with the second dopant having a lighter atomic weight than the first dopant; \n a semiconductor layer on the substrate, comprising a first diffuse region on the first buried layer and a second diffuse region on the second buried layer, with the first and the second diffuse regions both comprising the second dopant; a first connection component extending from an upper surface of the semiconductor layer to the first diffuse region; and a second connection component extending from the upper surface of the semiconductor layer to the second diffuse region, with the first and the second connection components both having the first conductive type.
