An object of the present invention is to provide a semiconductor device using a cheap glass substrate, capable of corresponding to the increase of the amount of information and further, having a high performance and an integrated circuit capable of operating at a high rate. A variety of circuits configuring an integrated circuit are formed on a plurality of glass substrates, the transmission of a signal between the respective glass substrates is performed by what is called an optical interconnect using an optical signal. Concretely, alight emitting element is provided on the output side of a circuit disposed on the upper stage formed on one glass substrate, and a photo-detecting element is formed so as to oppose to the relevant light emitting element on the input side of a circuit disposed on the rear stage formed on another glass substrate. Then, an optical signal converted from an electrical signal outputted from a circuit disposed on the upper stage is outputted from the light emitting element, the relevant optical signal is converted into an electrical signal by a photo-detecting element and inputted into a circuit disposed on the rear stage. |
