Abstract

PURPOSE: To obtain a high-speed and low power loss I2L by securing insulation for the emitter region of I2L injector transistor by means of the sapphire substrate at the lower part of the emitter region and also giving insulation to the peripheral areas excluding the effective base region by means of the insulator film each.
