Abstract
A semiconductor device which includes a passivation structure formed with a conductive strip of resistive material that crosses itself once around the active region of the device to form a first closed loop, a continuous strip that loops around the first closed loop without crossing itself which crosses itself a second time to form a second closed loop.
Claims3
A semiconductor device comprising:
- a semiconductive body having an active region formed therein;
- a continuous strip of resistive material looping around said active region without crossing itself and including PN junctions formed therein;
- and
- a metallic layer formed over at least one of said PN junction.
