A circuit is provided which prevents dendrite formation on interconnects
during semiconductor device processing due to a dendrite-forming current.
The circuit includes a switch located in at least one of the
dendrite-forming current paths. The switch is configured to be open or in
the "off" state during processing, and is configured to be closed or in
the "on" state after processing to allow proper functioning of the
semiconductor device. The switch may include an nFET or pFET, depending
on the environment in which it is used to control or prevent dendrite
formation. The switch may be configured to change to the "closed" state
when an input signal is provided during operation of the fabricated
semiconductor device.
