Abstract

PURPOSE: To uniformly set a wiring density and to integrate without increasing the number of tracks by blocking cell row groups, wiring with the first and second wiring layers in the block, and wiring between the blocks with the third wiring layer.
CONSTITUTION: A chip is divided into four blocks, and one is used for function blocks 5 such as ROM, RAM, PLA. The remaining three blocks are composed of cell rows 2 in which several types of standard cells 3 of NAND, NOR of the minimum units of logic functions are aligned in many rows. The length of the cell row is decided so that the number of tracks of the cell row direction required for wiring between the cells 3 in each block becomes the width between the terminals of the adjacent cell rows, i.e., the wiring region, namely, the height of the cell, as the block number 3. The cell rows are disposed and wired in each block by the first layer aluminum in the direction along the row and the second layer aluminum in the direction perpendicular thereto by a CAD. Then, the connection between the blocks in lateral direction is decided by the third aluminum wiring layer. The connection between the blocks in elevational direction uses the second layer aluminum. This is to eliminate the contact with the third layer aluminum.
