Abstract:
1. A method of fabricating a semiconductor device, comprising: preparing a first semiconductor wafer; forming a concave portion in the first semiconductor wafer; disposing a signal processing circuit in the concave portion; mounting a semiconductor sensor chip on the signal processing circuit; connecting a second semiconductor wafer that is a plate-lie member and that covers the concave portion to the first semiconductor wafer, said connecting includes bonding the second semiconductor wafer to the first semiconductor wafer to form a hollow case, the semiconductor sensor chip being mounted within the hollow case, the signal processing circuit being formed in a bottom of the concave portion and under the semiconductor sensor chip, the semiconductor sensor chip being supported on the signal processing circuit and being free of direct contact with the plate-like member; and cutting the first semiconductor wafer and the second semiconductor wafer into individual pieces.
