  • Integrated lateral transistor with improved current amplification
    Patent number: 5596220
    Abstract: A method of manufacturing an integrated lateral transistor in which the depth and the doping level of the emitter region are such that the diffusion length of the minority carriers vertically injected into it is larger than or equal to the thickness of the emitter region. The distance between the peripheries of an electrical emitter connection zone and the emitter region is nominally larger than the alignment tolerance of an emitter contact window. This permits obtaining a transistor having an improved current amplification. An integrated circuit includes a lateral transistor, in which the ratio between the surface of the emitter region and that of the electrical emitter connection zone advantageous lies between 20 and 200.
