Back-thinned CCD image sensors with
electronic shutter function
The S11155-2048 and S11156-2048 are back-thinned CCD linear image sensors with an internal electronic shutter for spec-
trometers. These image sensors use a resistive gate structure that allows high-speed transfer. Each pixel has a lengthwise size
needed by spectrometers but ensures readout with low image lag.

Resistive gate structure
In ordinary CCDs, one pixel contains multiple
electrodes and a signal charge is transferred by
applying different clock pulses to those elec-
trodes [Figure 1]. In resistive gate structures,
a single high-resistance electrode is formed in
the active area, and a signal charge is trans-
ferred by means of a potential slope that is
created by applying different voltages across
the electrode [Figure 2]. 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.
