PURPOSE:To make a channel temperature uniform by arranging stripe electrodes in a gate region that electrode intervals in the central part of a semiconductor chip are different from those in the vicinity of its both end parts. CONSTITUTION:The intervals of gate stripe fingers 6 are arranged so that an interval B in the central part of a chip is relatively larger than an interval B in its both end parts. Accordingly, overlapping of heat generation in a channel part can be alleviated in the central part of the chip and the heat resistance of the effective chip of the central part can be reduced. When a field-effect transistor performs high-frequency and high-output operation, uniforming and reduction of a channel temperature of the chip can be contrived and enhancement of an output and reliability are improved.
