Abstract:
An AC switch device comprising:a first semiconductor region of a second conductivity type formed on a semiconductor substrate of a first conductivity type, the second conductivity type being different from the first conductivity type;second and third semiconductor regions of the first conductivity type, separately formed in the first semiconductor region;fourth and fifth semiconductor regions of the second conductivity type, separately formed in the second semiconductor region;sixth and seventh semiconductor regions of the second conductivity type, separately formed in the third semiconductor region;a first channel region formed in an upper part in the second semiconductor region between the fourth and fifth semiconductor regions, on the one hand, and the sixth and seventh semiconductor regions, on the other;a second channel region formed in an upper part in the third semiconductor region between the fourth and fifth semiconductor regions, on the one hand, and the sixth and seventh semiconductor regions, on the other;a first control electrode formed above the first channel region with an insulating film interposed; anda second control electrode formed above the second channel region with an insulating film interposed.
