Abstract
An information processing device having neural network functions for performing information processing comprises: a semiconductor integrated circuit section including a plurality of neuronic circuit regions having a neuronic function which is one of said neural network functions, and first and second molecular film provided on the integrated circuit section. The first molecular film has a photoelectric function and the second molecular film has a light-emitting function. Coupling between the plurality of neurons is realized through a combination or the light-emitting and light receiving functions of the first and second molecular films.
