Patent number: 9029976Abstract: Provided is a semiconductor device which increases a concentration around an emitter by arranging a lightly doped region (HNMLDD). When the semiconductor device is operated in a forward bias, a maximum common-emitter current gain is obtained in a forward-active region, such that signals are amplified and an unnecessary noise is decreased at the same time. Further, the semiconductor device of the invention further includes a field plate disposed on a substrate between the emitter and a base or/and the collector and the base, and configured to change a potential distribution of junctions between each of doped regions and raise a breakdown voltage of the junctions.Type: GrantFiled: December 27, 2013Date of Patent: May 12, 2015Assignee: MACRONIX International Co., Ltd.Inventors: Chih-Ling Hung, Hsin-Liang Chen, Wing-Chor Chan
