DETECTION DEVICE FOR TWO DIFFERENT COLORS WITH IMPROVED OPERATING CONDITIONS CAPABLE OF IMPROVING ELECTRICAL PERFORMANCE

摘要

PURPOSE: A detection device for two different colors with improved operating conditions is provided to prevent a short circuit between two semiconductor layers.;CONSTITUTION: A first contact(19) is connected to a second electrode of a first photo diode. A second biasing pad(10) is electrically connected to a second semiconductor layer. A second contact(18) is connected to the second electrode of a second photo diode. A first biasing circuit(8b) applies a first electric potential difference between a first biasing pad and the first contact. A second biasing circuit(8a) applies a second electric potential difference between a second biasing pad and the second contact.;COPYRIGHT KIPO 2013
