Abstract
In a solid-state imaging device and its production method according to the present invention, a solid-state image sensor has an effective light-receiving region on a circuit formation surface provided in a face-down condition. A transparent substrate has a conductor pattern provided thereon to confront the circuit formation surface of the image sensor. A transparent adhesive agent is provided between the image sensor and the substrate and formed into a thin layer, the adhesive agent covering the light-receiving region of the image sensor. A plurality of bumps are provided on one of the image sensor and the substrate to interconnect the image sensor and the conductor pattern of the substrate.
