PROBLEM TO BE SOLVED: To provide a semiconductor device which can reduce loss of shape in a pattern which is formed in a semiconductor device in the past by coating a phase transition material as a heat radiation material, even when an impact is made on the pattern formed by the phase transition material in a liquid state in an atmosphere where temperature control is not satisfactory.SOLUTION: A semiconductor device comprises: a semiconductor element mounted inside a semiconductor module 10; a heat radiation surface 13 formed on the semiconductor module 10, for radiating heat generated by the semiconductor element to a radiator; a pattern 14 which is composed of a phase transition material and formed on the heat radiation surface; and a film 15 as a first film for covering the pattern 14. |
