DUAL-CHANNEL CHARGE-COUPLED SEMI-CONDUCTOR DEVICE

摘要

A bipolar dual-channel charge-coupled device having a first channel at the surface for storing a first bit stream of minority charge carrier packets and a second channel buried in the bulk for storing a second bit stream of majority charge carrier packets. The two bit streams are transferred along their respective surface and buried channels simultaneously and independently of each other, thereby substantially increasing the bit storage density of the chip.
