SANYO fabricates frame transfer (FT) CCD sensors using unique technologies with ultrafine design rules and provides them as
modules assembled using advanced leading-edge mounting technologies.
SANYO makes a point of providing fine and delicate semiconductor devices in forms that our customers will find approachable
and easy to use.

High image quality, ultraminiature size, and low power makes these devices optimal for
use in cell phones

Frame Transfer Full-Color CCD Sensors

Achieves the industry’s smallest optical size class by using the frame transfer CCD, which makes it possible to reduce
feature sizes while maintaining sensitivity.
Sensitivity was increased by adopting a simple single-layer gate gap structure and thin-film polysilicon.

IL-CCD

A charge pump type voltage step-up circuit that features minimal noise generation, and the supply voltages required for
system drive are generated efficiently with just the supply of a single +2.9 V power supply. This design is also effective at
achieving reduced power consumption.
SANYO implemented, in a single package, the timing generator circuit required for system drive and all the analog and
digital processing required to accept the CCD output by taking advantage of the SANYO CMOS analog/digital hybrid
process and MCP (multi-chip package) technologies.

The FT CCD method uses
no elements that block the
entrance of light, and thus
they can capture light from
a wider range of incidence
angles.

High sensitivity

Reducing the device 

height is possible

In the 1.0-MP CCD, SANYO developed a new charge accumulation method.
Low moire, high sensitivity, and a high frame rate achieved by pixel addition during preview and spatial
filter processing.
