INTEGRATED CIRCUIT OF ULTRA-FINE VOLTAGE ISLAND

摘要

PROBLEM TO BE SOLVED: To provide an integrated circuit of an ultra-fine voltage island. SOLUTION: A method of applying a voltage to an integrated circuit is provided. A high-voltage VddH and/or a low-voltage VddL is supplied to a filler cell 16 and is applied to other cells. Each voltage VddH and each voltage VddL are applied by either of a first voltage supply wiring 6 or a second voltage supply wiring 8. A voltage application wiring 4 applies a required voltage to the filler cell. The first and second voltage supply wirings 6 and 8 are preferably in parallel with the voltage application wiring 4, and its end is aligned on the end of the voltage application wiring 4. A via 10 is formed, and the required voltage is applied. Preferably, the first voltage supply wiring 6 is M1 wiring formed outside a filler cell 16 range, and the second voltage supply wiring 8 is M2 wiring formed inside the filler cell 16 range.
