Abstract:
1. A semiconductor device grounding structure comprising: a circuit substrate having a plurality of connection pads and a grounding wiring; a semiconductor device including a semiconductor substrate which has a first face and a second face opposite thereto, and a first side surface and a second side surface opposite thereto, wherein an insulating film is formed on the first face of the semiconductor substrate, an SOI integrated circuit including a plurality of connection pads is provided on the insulating film, and electrodes for external connection are connected to the connection pads of the SOI integrated circuit, respectively, the electrodes for external connection being connected to the connection pads of the circuit substrate, respectively, by a face-down bonding scheme; an under-filling material provided between the semiconductor device and the circuit substrate; and a conductive paste which connects the second face of the semiconductor substrate with the grounding wiring of the circuit substrate along only one of the first and second side surfaces of the semiconductor substrate; and wherein the conductive paste is fixed to the second face of the semiconductor substrate, said one of the first and second side surfaces of the semiconductor substrate, and the grounding wiring of the circuit substrate.
