    Abstract: A high voltage bipolar transistor with shallow trench isolation (STI) comprises the areas of a collector formed by implanting first electric type impurities into active area and connected with pseudo buried layers at two sides; Pseudo buried layers which are formed by implanting high dose first type impurity through the bottoms of STI at two sides if active area, and do not touch directly; deep contact through field oxide to contact pseudo buried layers and pick up the collectors; a base deposited on the collector by epitaxial growth and in-situ doped by second electric type impurity, in which the intrinsic base touches local collector and extrinsic base is used for base pick-up; a emitter which is a polysilicon layer deposited on the intrinsic base and doped with first electric type impurities. This invention makes the depletion region of collector/base junction from 1D (vertical) distribution to 2D (vertical and lateral) distribution. The bipolar transistor's breakdown voltages are increased by only enlarge active critical dimension (CD). This is low-cost process.
