Abstract
One embodiment of the present invention provides a system that electronically aligns mini-bars on different semiconductor chips which are situated face-to-face to facilitate communication between the semiconductor chips through capacitive coupling. During operation, the system measures an alignment between a first chip and a second chip. The system then selects a group of transmitter mini-bars on the first chip to form a transmitter bit position based on the measured alignment. In this way, the system allows a data signal to be distributed to and transmitted by the mini-bars that form the transmitter bit position. The system also selects a group of receiver mini-bars on the second chip to form a receiver bit position based on the measured alignment. Next, the system associates transmitter bit positions on the first chip with proximate receiver bit positions on the second chip based on the measured alignment. In this way, the system allows data signals transmitted by the mini-bars within a transmitter bit position on the first chip to be collectively received by the mini-bars within an associated receiver bit position on the second chip.
