IPC: H01L31/10
Filed: 1989-12-15
Abstract: PURPOSE:To obtain a semiconductor device, in which the effect of the peripheral section of an emitter region is removed and characteristics of which are not deteriorated even when fined, by positioning the joint surfaces of the emitter region and a base region at the same location as the interface of an insulating film and the base region while making the impurity concentration of the emitter region lower than that of the base region on the joint surfaces. CONSTITUTION:The joint surfaces of an emitter region 5a and a base region 4 are brought to the same height as the interface of the base region 4 and an insulating film 102. The joint surfaces of the emitter region 5a and the base region 4 may be positioned at a location higher than the interface of the base region 4 and the insulating film 102. Since the impurity concentration of the emitter region 5a is made lower than that of the base region 4, a depletion layer extends to the emitter region 5a side, field strength is equalized, and the strong field strength section of a periphery is removed. Accordingly, no current concentration is generated around an emitter, and the deterioration of a current amplification factor hFE to hot carriers arising at a time when the fining of a BPT is performed can be prevented.
