    摘要: To form NPN and PNP transistors on the same base for example to obtain a complementary bipolar transistor (1) it has been necessary to make an epitaxial layer a thick film, and this has resulted in deterioration of the characteristics of the NPN transistor. Also, because a step of forming an alignment mark has been necessary this has increased the number of manufacturing steps needed to make a complementary bipolar transistor. This invention provides a semiconductor device manufacturing method which solves this problem as follows: After a first opening (13) [alignment mark (16)] and a second opening (14) are formed in an insulating film (12) formed on a semiconductor base (11) and a doping mask (15) is then formed on the semiconductor base (11), a third opening (17) is formed thereon with the alignment mark (16) as a reference. After an impurity (18) is introduced into the semiconductor base (11) through the third opening (17), the doping mask (15) is removed and after that an impurity (19) is introduced into the semiconductor base (11) by solid-phase diffusion through the second opening (14) and a first embedded diffusion layer (20) is thereby formed and at the same time the impurity (18) is caused to diffuse and form a second embedded diffusion layer (21). Then, after an epitaxial layer is formed, an impurity diffusion layer is formed therein by ion injection (not shown).

    摘要: A process for fabricating Ultra Large Scale Integrated (ULSI) circuits in Silicon On Insulator (SOI) technology in which the device structures, which can be bipolar, FET, or a combination, are formed in vertical silicon sidewalls having insulation under and in back thereof so as to create SKI device structures. The silicon sidewall device SOI structures, when fabricated, take the form of cells with each cell having a plurality of either bipolar devices, FET devices, or a combination of these devices, such as collectors, emitters, bases, sources, drains, and gates interconnected within the planes of the regions of the devices in the cells and can be interconnected within the planes of the regions of devices in adjacent cells. Further, the interconnections to adjacent cells can be made from the back of the silicon sidewalls.

    摘要: A process for creating self-aligned vertically arrayed planar transistors. The preferred embodiment relates to the simultaneous fabrication of both NPN and PNP planar vertically arrayed transistors in a conventional monolithic, epitaxial, PN junction isolated, integrated circuit. A field oxide is employed to surface isolate the devices and assist in the self-alignment improvement.
