Semiconductor device

Abstract

According to one embodiment, a semiconductor device includes first and second transistors, a light emitter, a light receiver, first and second spacers. The first transistor is provided above a first surface of a board. The second transistor is provided above the first surface of the board and arranged in a first direction along the first surface of the board with respect to the first transistor. The light emitter is provided above the first surface of the board, and arranged in a second direction perpendicular to the first direction and along the first surface with respect to the first and second transistors. The light receiver is provided above the first and second transistors and the light emitter. The first spacer is provided between the first transistor and the light receiver, and electrically connects them. The second spacer is provided between the second transistor and the light receiver, and electrically connects them.
