Filed: 1983-09-20
Abstract: PURPOSE:To improve the characteristics of a logic circuit and to improve the integration by constructing to dispose arrays of transistors of different sizes in the vicinity. CONSTITUTION:A plurality of arrays 20 of transistors of large size and a plurality of arrays 30 of transistors of small size are adjacently formed in such a manner that the transistors of large and small sizes are as a pair. When the transistor arrays 20 of large size and the transistor array 30 of small size are formed as pairs in this manner, in case that a flip-flop is, for example, formed with two inverters, an output stage may use only one of a basic cell 21 of large size (the number of the transistors is 2 since CMOS is used), and a basic cell 31 of small size is used for the internal gate (an inverter for latch or feedback). Accordingly, an area may be narrow, and the characteristics of the circuit can be improved.
