Title: Semiconductor device with sea-of-gates array transistors on linear active region - has active region transistors connected via stop transistor gate so that stop transistor failure inhibits operation
Inventor: DENNER WERNER DIPL PHYS DR RER
IPC: H01L27/118
Filed: 1991-03-18
Abstract: The semiconductor device has a linear active region (1) across which a series of field effect transistors (T1 to T4) are fabricated.
