Lateral transistor structure optimization with respect to current gain
Keyword(s):
An investigation of a novel lateral transistor structure fabricated in standard 4 μm complementary metal oxide semiconductor technology without any additional processing steps is presented. Inherent in the structure is the potential of modulating the lateral electric field in the neutral base region. An additional characteristic of this structure is the reduced bottom surface of the emitter, which diminishes the parasitic action of vertically injected carriers. The results show that because of the lateral electric field, the common-emitter static current gain at high currents can be increased by at least an order of magnitude.
