Abstract:
(EN) The present invention relates to a gallium nitride-based sensor having a photostimulatable structure and a manufacturing method therefor. The method comprises the steps of: growing an LED epitaxial layer on a substrate; growing a high-resistance (HR)-GaN layer on the LED epitaxial layer; sequentially growing one selected from the group consisting of a u-GaN layer and AlxGa1-xN layer and an InxAl1-xN layer and InxAlyGa1-x-yN layer on the HR-GaN layer; performing a patterning process to allow the formation of an electrode on the LED epitaxial layer; forming an electrode according to the pattern established on the LED epitaxial layer; and forming a sensing material layer on the one layer selected from the group consisting of the AlxGa1-xN layer, the InxAl1-xN layer, and the InxAlyGa1-x-yN layer.
(FR) La présente invention concerne un capteur à base de nitrure de gallium possédant une structure photostimulable et son procédé de fabrication. Le procédé comprend les étapes consistant à : faire croître une couche épitaxiale de DEL sur un substrat ; faire croître une couche de (HR)-GaN à haute résistance sur la couche épitaxiale de DEL ; faire croître successivement une couche choisie dans le groupe constitué d'une couche de u-GaN et d'une couche de AlxGa1-xN, et d'une couche de InxAl1-xN et d'une couche de InxAlyGa1-x-yN sur la couche de HR-GaN ; mettre en œuvre un procédé de formation de motif pour permettre la formation d'une électrode sur la couche épitaxiale de DEL ; former une électrode selon le motif dessiné sur la couche épitaxiale de DEL ; et former une couche d'un matériau de détection sur ladite couche, sélectionnée dans le groupe constitué de la couche d'AlxGa1-xN, la couche de InxAl1-xN et la couche de InxAlyGa1-x-yN.
(KO) 광자극 구조를 구비한 질화갈륨계 센서 및 그 제조 방법으로, 기판에 LED 에피층을 성장시키는 단계와; 상기 LED 에피층 상에 HR(High-resistance)-GaN 층을 성장시키는 단계와; 상기 HR-GaN 층 상에 u-GaN 층 및 AlxGa1-xN층, InxAl1-xN층 및 InxAlyGa1-x-yN층으로 이루어지는 군에서 선택되는 1종의 층을 순차적으로 성장시키는 단계와; 상기 LED 에피층에 전극을 형성할 수 있도록 패터닝을 수행하는 단계와; 상기 LED 에피층에 형성된 패턴에 따라 전극을 형성시키는 단계와; 상기 AlxGa1-xN층, InxAl1-xN층 및 InxAlyGa1-x-yN층으로 이루어지는 군에서 선택되는 1종의 층 상에 검지물질층을 형성시키는 단계를 포함한다.
