Figure 5 shows a representative spectral response of front
side illuminated transparent gate full frame image sensors.
The KAF−1001 with 24 m m pixels has higher response than
the 6.8 mm pixel sensor at wavelengths greater than 750 nm
because it is constructed on a lower resistivity silicon
substrate. The resulting collection volume of each pixel
more efficiently collects signal generated deeper within the
silicon.
Most of the two phase CCD pixels are designed so that
each of the electrodes occupies half of the pixel area.
The KAF−1001 was not designed this way but instead is
designed with the transparent electrode occupying greater
than half the pixel area. This further improves the benefits
of the transparent gate.
