  • High-voltage pull-up device
    Patent number: 4868620
    Abstract: An integrated circuit in which a large potential can be maintained between the source of the device and the substrate on which this device and other devices are fabricated is described. The circuit employs a minority carrier sink region to remove minority carriers from the gate region of a MOS depletion device. The sink region is shielded from the substrate by a buried layer which prevents punch-through between the sink region and the substrate.
