Abstract:
컬러필터격리층을구비하는이미지센서및 상기이미지센서의제조방법이개시된다. 개시된실시예에따른이미지센서는, 입사광중에서특정파장대역의빛을투과시켜광센싱층에제공하는다수의컬러필터및 다수의컬러필터들사이에배치된격리층을포함할수 있다. 격리층은컬러필터들의굴절률보다낮은굴절률을갖는재료로이루어지기때문에컬러필터의측면으로빠져나가는빛을전반사할수 있다. 따라서, 컬러필터에경사지게입사하여컬러필터의측면으로빠져나가는빛이다시원래의컬러필터로되돌아올수 있다.
Abstract:
A thermopile type infrared detector and an infrared image sensor having the same are disclosed. The disclosed infrared detector includes at least one infrared absorber which is formed on a substrate and includes a plasmonic resonator or a metamaterial resonator; and thermocouples which receive thermal energy generated by the at least one infrared absorber and generate an electromotive force.
Abstract:
Disclosed is an infrared detector capable of detecting the infrared spectrum of a large broadband by using a surface plasmon resonator of the broadband. The disclosed infrared detector includes a thermistor member and a resonator which is arranged on the thermistor member and is configured to cause a surface plasmon resonance in multiple resonance modes. The disclosed infrared detector is able to absorb an electromagnetic wave which has an infrared wavelength of a large broadband with one resonator, and have an improved signal-to-noise ratio.
Abstract:
PURPOSE: An infrared detection device and an infrared detection method using the same are provided to correct a temperature change and a resistance change caused by an external environment, thereby sensing the temperature change and the resistance change caused by infrared rays becoming incident. CONSTITUTION: An infrared detection device (100) comprises a first metal layer (120), a second metal layer (160), a thermister layer (170), a thermal leg (150), and a controller (195). The second metal layer is arranged separately from the first metal layer and absorbs infrared rays becoming incident. The thermister layer supports the second metal layer, and a resistance value is changed according to a temperature change caused by the infrared rays absorbed by the second metal layer. The thermal leg supports the thermister layer and is arranged separately from the first metal layer. The control unit adjusts a distance between the first metal layer and the thermal leg.
