Abstract
One embodiment of the present invention provides a system that automatically detects and corrects a misalignment of a semiconductor chip. During operation, the system uses a position-detection mechanism integrated with the chip to determine the misalignment of the chip from a desired alignment for the chip. Next, the system uses an actuation mechanism integrated with the chip to automatically correct the misalignment, thereby improving performance and reliability of the chip.
