A planar integrated emitter polycrystalline silicon-germanium heterojunction bipolar transistor was developed. The design of SiGe HBT was carried out and analyzed. The bipolar transistor structure and key process parameters were studied and analyzed, and finally the tape out was tested. The results show that at room temperature current gain β is greater than 1 500, and the greatest is up to 3 000, V_(ceo) is 5 V,Overly-vohage V_A is greater than 10 V, βV_A product reaches more than 15 000. This device is very sensitive to the arsenic impurity concentration distribution of polysilieon emitter.
