While the competitive advantage of Japanese companies in the semiconductor industry has declined significantly, the competitive advantage of Japanese companies in the power semiconductor field is still maintained. Based on the architectural theory that Japanese companies have strengths in industries that require matching, this study analyzed the factors of matching in the field of power semiconductors. As a result of comparing the relationship between the functional design, structural design and process design of logic ICs and power semiconductors, which are typical products of the semiconductor industry, there was a strong dependency between the functional design of power semiconductors and the process design. It was shown that the strong dependence between functional design and process design is one of the competitive advantage factors of Japanese companies in the field of power semiconductors.
