DETECTION DEVICE FOR TWO DIFFERENT COLOURS WITH IMPROVED OPERATING CONDITIONS |
摘要 |
The substrate includes successively a first semiconductor layer having a first bandgap energy, a semiconductor buffer layer, a second semiconductor layer having a first bandgap energy different from the first bandgap energy. Two photodetectors sensitive to two different colors are formed respectively on the first and second semiconductor layers. A first biasing pad electrically connects the first semiconductor layer to a first biasing circuit. A second biasing pad electrically connects the second semiconductor layer to a second biasing circuit. The first biasing pad is devoid of electrical contact with the second semiconductor layer.
