Patent number: 4882290Abstract: In an NPN transistor, a contact base region, an active base region, and a further base region are formed in the silicon substrate. The further base region is between the contact base region and the active base region, and is adjacent to the contact base region and the active base region. The further base region has a depth shallower than that of the contact base region and deeper than that of the active base region. In the method of forming the bipolar transistor, a polysilicon semiconductor layer is formed on a semiconductor substrate. The polysilicon semiconductor layer is partially etched to form a base leading electrode and an emitter leading electrode. A semiconductor impurity is implanted into a base forming region of the silicon substrate via that portion where the polysilicon semiconductor layer is removed.Type: GrantFiled: January 25, 1988Date of Patent: November 21, 1989Assignee: Kabushiki Kaisha ToshibaInventor: Shigeru Komatsu

Patent number: 4879252Abstract: The method of manufacturing a semiconductor device according to the present invention comprises the step of forming an opening in use for forming an emitter region. This step uses the independent etching characteristics of N and P type polysilicons to simplify the opening forming process, which is very complicated in the conventional method. To be more specific, the impurity doped in the first polysilicon layer at a high concentration is diffused into the second polysilicon layer adjacent to the first polysilicon layer. When the impurity doped in the first polysilicon layer is diffused into the second polysilicon layer, the diffused impurity dominantly determines the conductivity type of that portion of the second polysilicon layer, into which the impurity is diffused. Therefore, one of the first polysilicon layer and the second polysilicon layer portion is etched by a solution, independently of the other.Type: GrantFiled: January 25, 1988Date of Patent: November 7, 1989Assignee: Kabushiki Kaisha ToshibaInventor: Shigeru Komatsu

An emitter region is formed in the base region. A polycrystalline silicon layer is buried in the insulating films to have ohmic contact with the base region and serve as a portion of a base connection region. The polycrystalline silicon layer contains a p-type impurity and serves as an impurity diffusion source for the formation of an external base of the base region.
