Semiconductor integrated circuit
Abstract:
A semiconductor integrated circuit according to an example of the present invention includes a chip substrate, first and second switches arranged on the chip substrate in which ON/OFF of an electrical signal path is directly controlled by an optical signal, a first light shielding layer arranged above the chip substrate, an optical waveguide layer arranged on the first light shielding layer, a second light shielding layer arranged on the optical waveguide layer, a reflecting plate arranged in the optical waveguide layer to change an advancing direction of the optical signal, and means for leading the optical signal to the first and second switches from an inside of the optical waveguide layer. The first and second light shielding layers reflect the optical signal, and the optical waveguide layer transmits the optical signal radially.
