Abstract
In a semiconductor integrated circuit device having at least two logic blocks each including at least two logic units each having a number of MOS FET's integrated therein, bipolar transistors for driving the MOS FET's are selectively arranged between the logic blocks and/or the logic units so as to shorten the critical path of a logic block.
