Abstract
A multiple transistor consists of vertical and lateral transistors, the collector region of the lateral transistor is formed by diffusion within the diffused base region of the vertical transistor simultaneously with the emitter region of the vertical transistor, into a structure in which the base of the vertical transistor and the collector of the lateral transistor are short-circuited. As a result the current gain of the lateral transistor can be varied by changing the area of the collector region.
