Abstract:
1. A semiconductor device comprising: a substrate that contains a semiconductor substrate, a first insulating layer formed on the semiconductor substrate, a first semiconductor layer formed on the first insulating layer, a second insulating layer formed on the first semiconductor layer, a second semiconductor layer formed on the second insulating layer, a gate insulating layer formed on the second semiconductor layer, and a gate electrode layer formed on the gate insulating layer, in this order; an optical waveguide that is formed along a predetermined path, said optical waveguide being formed by making the first semiconductor layer non-uniformed in thickness thereof; and a photoreceptor having MISFET containing a floating channel body that is formed by the second semiconductor layer on a position of the first semiconductor layer in which electric field of light guided inside the optical waveguide exists and a gate for forming channel formed on a front surface side of the channel body.
