Patent ID: 11824134

Abstract:
A semiconductor device includes a light-emitting element, a light-receiving element, a switching element, an input-side terminal, an output-side terminal, and a resin layer. The light-emitting element, the light-receiving element and the switching element are provided at the front side of the resin layer. The light-receiving element and the switching element are arranged in a first direction along the front side of the resin layer. The switching element is electrically connected to the light-receiving element. The light-receiving element is provided between the light-emitting element and the resin layer. The input-side and output-side terminals are provided at the backside of the resin layer. The input-side terminal is electrically connected to the light-emitting element. The output-side terminal is electrically connected to the switching element. At least one of the input-side or output-side terminals includes a portion overlapping the light-emitting element in a second direction from the resin layer to the light-emitting element.
