S55-048-0 S56-048-0 Back-thinned CCD image sensors with electronic shutter function The S55-048-0 and S56-048-0 are back-thinned CCD linear image sensors with an internal electronic shutter for spectrometers. These image sensors use a resistive gate structure that allows a high-speed transfer. Each pixel has a lengthwise size needed by spectrometers but ensures readout with low image lag. Image lag on these products is reduced by nearly a magnitude of as compared to the previous products (S55-048-0, S56-048-0). Note that the transmission of long wavelengths in the dead layer covering the horizontal shift register was reduced compared to previous products. Features Built-in electronic shutter Minimum integration time: μs High sensitivity from the ultraviolet region (spectral response range: 00 to 0 nm) Readout speed: MHz max. Image lag: 0.% typ.

In resistive gate structures, a single high-resistance electrode is formed in the active area, and a signal charge is transferred by means of a potential slope that is created by applying different voltages across the electrode [Figure ]. Compared to a CCD area image sensor which is used as a linear sensor by line binning, a one-dimensional CCD having a resistive gate structure in the active area offers higher speed transfer, allowing readout with low image lag even if the pixel height is large.

However, long-wavelength light passes through the silicon dead layer and may possibly be detected by the horizontal shift register. To prevent this, provide light shield on that area as needed. Note that the transmission of long wavelengths in the dead layer covering the horizontal shift register was reduced compared to previous products. Signal charges that undergo photoelectric conversion at each pixel of the photosensitive area are directed upward or downward based on the boundary line at the center of the photosensitive area and transferred.then, they are combined through the horizontal registers and read out by the amplifier.
