PROBLEM TO BE SOLVED: To provide a layout designing method by which the intervals among transistors can be decided relatively easily and, at the same time, can make the temperature distribution in a chip relatively uniform in a high-output power transistor, which is constituted by connecting a plurality of transistors in parallel with each other and operated as one transistor. SOLUTION: In the semiconductor integrated circuit provided with an output circuit composed of a plurality of transistors (Q1-Qn) arranged on one semiconductor chip in a matrix-form, a plurality of blocks is designed in such a way that the transistors on the same line are divided into groups of a prescribed number of transistors each and, in each block, the transistors are arranged at a regular interval (L1). In addition, the interval (L2) between the blocks is made larger than that between the transistors in each block. |
