Abstract
A transistor formed in a master slice manner is disclosed for use in radio frequency range, the transistor includes a main transistor cell operating as a smallest transistor in scale among a product group of transistors, and sub-transistor cells are arranged at symmetrical positions with the main transistor cell as the center. The sub-transistor cells are connected in common or not to the main transistor in a master slice manner in accordance with the required characteristics.
