1. A semiconductor apparatus, comprising:
a semiconductor substrate including electrical circuitry that is contained within the semiconductor substrate;
a thin semiconductor film disposed on the semiconductor substrate, the thin semiconductor film being formed separately from the semiconductor substrate and attached to the semiconductor substrate, the thin semiconductor film including at least one semiconductor device; and
an interconnecting line disposed on respective surfaces of the thin semiconductor film and the semiconductor substrate, interconnecting the semiconductor device with the electrical circuitry, the interconnecting line including a probe pad disposed on the semiconductor substrate between the thin semiconductor film and the electrical circuitry, the probe pad being wider than parts of the interconnecting line other than the probe pad, the probe pad being used for testing whether the electrical circuitry operates normally.
