Abstract
The disclosure relates to a system for protecting HgCdTe and the like MIS arrays from breakdown during fabrication due to electrostatic charge buildup on the array capacitors. This is accomplished by building into the structure a short circuit across the capacitor plates with a fuse region therein that will evaporate when a voltage is placed thereacross which is sufficient to cause evaporation and low enough not to damage the capacitors.
