    Abstract: Several techniques are provided to reduce the spurious reflection generated at the exit surface of a transmission grating. In one embodiment the exit surface of the grating is not parallel with the entrance surface. In another embodiment, the first and second surfaces of the grating are parallel and a second substrate is attached to the second surface of the grating. The second substrate has an entrance surface and an exit surface having at least a wedge angle relative to the entrance surface. In another embodiment, a second substrate is fixedly connected to the second surface of a parallel plate grating, where the second substrate has an entrance surface and an exit surface. The exit surface is curved such that it will be about normal to a beam transmitted over a range of angels of incidence onto the grating region.

    Abstract: A method for manufacturing a semiconductor device for detecting a physical amount distribution, the semiconductor device comprising unit components arrayed in a predetermined order, the unit components each including a unit signal generation portion for detecting an electromagnetic wave and outputting the corresponding unit signal. A diffraction grating is provided on the incident light side of a spectral image sensor, the diffraction grating including scatterers, slits, and scatterers disposed in that order. An electromagnetic wave is scattered by the scatterers to produce diffracted waves, and by using the fact that interference patterns between the diffracted waves change with wavelengths, signals are detected for respective wavelengths by photoelectric conversion elements in each photodiode group.
