Abstract:
Disclosed is an optical information storage device using a composite structure of Conductor-Insulator-Semiconductor. A large number of such devices when combined to form a matrix array, will provide an optical pattern memory to permit an optical pattern to be directly stored and to be retrieved either in visible form or in analogue output signal form.
Abstract:
A method for fabrication of a lateral transistor is disclosed, which comprises the step of diffusing base impurity by means of the RED method from the same masking hole determining an emitter region on a substrate which includes the emitter region and a collector region on the crystalline main plane thereof.
