The sensor allows the pilot light to be automatically re-ignited if the flame is no longer present. The circuit is a surprisingly simple one, with a PNP transistor being turned on by the flame ...

At the same time, by moving most transistors to their own layer, the individual size of each can also be increased. And not surprisingly, this is exactly what Sony has done. Lower noise levels and ...

Now, Sony's Semiconductor unit has announced the world's first stacked CMOS sensor with dual transistor layers that doubles the amount of light captured in comparison to a conventional stacked sensor.
