Patent JP-S63289859-A (JP)
Title: Semiconductor device and manufacture thereof
Inventor: KONAKA NOBUNORI
IPC: H01L29/732
Filed: 1987-05-21
Abstract: PURPOSE:To obtain a high electric-current cut-off frequency by a method wherein an impurity region of a first conductivity type whose concentration is higher than the impurity concentration in a collector region is formed only near a base-collector junction part directly under an emitter region. CONSTITUTION:An impurity region 10 whose concentration is higher than the impurity concentration of a collector region 11 and whose conductivity type is identical to that of the collector is formed only near a base-collector junction part 12 directly under an emitter region 4. Because the impurity region 10 exists directly under the emitter 4, the concentration of the collector in the base-collector junction part 12 becomes substantially high directly under the emitter 4; accordingly, a base expansion effect (the Kirk effect) caused during an operation by a high electric current is hard to cause. In addition, because this kind of impurity region is introduced, it is possible to suppress a tail of a distribution toward the side of the collector regarding an impurity distribution of a base which is formed normally by ion implantation. By this setup, a high electric-current out-off frequency can be obtained.
