This disclosure relates to a wafer scale power interconnect system by which defective circuits on the wafer can be automatically disconnected from the power and ground lines supplied to each of the circuits. The disconnect device employs a gate between the power source and the circuit, which gate is controlled by a fuse that can be destroyed by an excessive current thereby opening the gate. The disconnect device may also be just such a fuse or a current limiter.

Automatic power disconnect system for wafer scale integrated circuits

This disclosure relates to a controlled selective power disconnect means for employment with the various circuits implemented on a crystalline wafer so that a particular circuit can be selectively disconnected when it has developed a defect or short or is unwanted in the system for other reasons. The disconnect means employs a gate between the power source and the circuit, which gate is controlled by a fuse that can be melted or blown by a power disconnect signal thereby opening the gate. An amorphous switch can also be used such that networks can expand or contract around defective chips as required by the particular task or tasks involved.
