ABSTRACT:
A solid state area imaging apparatus having a photosensor matrix array disposed at a front surface area of a substrate and having a charge transfer arrangement for transferring charges generated in the photosensors of the matrix so as to convert them into a serial signal. It also includes a penetrative charge transfer arrangement for transferring the charge from the front surface area of the substrate to the back surface area of the substrate, and which has a static induction transistor structure. The charges are transferred vertically through a channel formed in the structure of the static induction transistor. This penetrative charge transfer arrangement may be used as a part of the transfer path for generating the serial signal or a path for removing excess charges which are generated in the photosensors.
