ABSTRACT:
This interconnect chip provides the function of an antifuse device. The interconnect chip is initially disconnected. Application of a high voltage applied across two terminals on the chip causes intrinsic polysilicon, which serves as an insulator between the connections to break down and form a reliable short circuit between the pads by redistribution of impurities from the layers above and below the intrinsic polysilicon.
