Abstract
A semiconductor device includes a substrate, a light-receiving element, a switching element, a light-emitting element on the switching element, first and second conductive members. The substrate includes first to third metal pads on a front-side thereof. The light-receiving element includes first and second bonding pads on a front-surface thereof. A back-surface of the light-receiving element is connected to the first and second metal pads. The first and second bonding pads each overlap one of the first and second metal pads. The switching element includes front-side and backside electrodes and a control pad. The backside electrode is connected to the third metal pad. The first conductive member is connected to the front-side electrode of the switching element and the first bonding pad of the light-receiving element. The second conductive member is connected to the control pad of the switching element and the second bonding pad of the light-receiving element.
