Abstract:
A semiconductor device and its manufacturing method are presented. The semiconductor device includes a collection region, a base region adjacent to the collection region, an emission region adjacent to the base region, and a doped semiconductor layer on the emission region. The width of the doped semiconductor layer is larger than the width of the emission region, a conductive type (e.g., P-type or N-type) of the doped semiconductor layer is the same as a conductive type of the emission region. In this inventive concept, the width of the doped semiconductor layer on the emission region is larger than the width of the emission region, that equivalently increases the width of the emission region, which in turn increases the DC amplification factor (β) and therefore improves the overall performance of the semiconductor device.

Claim (Index 16):
The method of  claim 13 , wherein the semiconductor structure further comprises:\n a first well region adjacent to the first base region and positioned next to the first base region along a first direction along which the second base region and the third base region are located; a second well region and a third well region separately located along the first direction on a same side of the first well region; a fourth well region whose doping concentration is higher than a doping concentration of the third well region, wherein the third well region is located between the fourth well region and the first well region; a gate structure on the second well region; and a source region and a drain region both located in the second well region and on two sides of the gate structure.
