Abstract :
A lateral phototransistor with stable sensitivity to a light input of the order of 10¿3lx was fabricated by a single selective diffusion of boron in n on n+ epitaxial wafer. An extended emitter electrode on SiO2, over a whole emitter-base surface junction is employed to obtain stable low-level current gain.
