STITCHED CIRCUITS LARGER THAN THE MAXIMUM RETICLE SIZE IN SUB-MICRON PROCESS

摘要

A circuit (100) having a plurality of circuit blocks (102-116, 122-124, 132-136, 142-146, 152-156) formed on a semiconductor substrate is disclosed. The circuit blocks are stitched together by appropriately connecting input and output lines of the plurality of circuit blocks. The circuit also includes connecting circuits (124, 134, 144, 152) coupled to the plurality of circuit blocks. The connecting circuits provide low voltage drop across boundaries where the plurality of circuit blocks are stitched together.
