Abstract:
본 발명은 기질 위에 수산화 기 단층을 형성하는 방법에 관한 것으로서, 반도체 또는 금속 표면에 할로겐 원소를 흡착시킨 후 물을 이용하여 수산화 기 단층을 형성하는 것을 특징으로 한다. 본 발명에 따르면, 반도체 또는 금속 표면에 수산화 기 단층을 형성할 수 있고, 박막 침착 공정에서 별도로 반도체 또는 금속 표면에 산화막을 형성할 필요가 없으며 특히 원자층 침착법 (atomic layer deposition, ALD) 공정 초기의 부화 기간 (incubation period)을 줄일 수 있는 장점이 있다. 본 발명에 따른 수산화 기 단층을 형성한 반도체 및 금속의 표면은 표면 과학의 새로운 연구 대상이 될 수 있고 또한 이들을 기질로 하여 분자 단층 (molecular monolayer)을 입힐 수 있다.

Abstract:
The present invention relates to a deposition device for an organic-inorganic hybrid thin film and a method for manufacturing an organic-inorganic hybrid thin film using the same. In the deposition device for an organic-inorganic hybrid thin film, an atomic layer deposition chamber for the deposition of inorganic matters and a thermal deposition chamber for the depositing of organic matters are vertically connected. A gate valve is arranged in a connection path connecting the chambers. An injection port for supplying an inorganic deposition source is arranged in the atomic layer deposition chamber. A unit for heating an organic deposition source is arranged in the thermal deposition chamber. In the formation of a molecular organic-inorganic thin film, the present invention can form the multi-layered physical thin film of the organic and inorganic layers using a thermal deposition method and an atomic layer deposition method and the multi-layered thin film of the organic and inorganic layers through a chemical combination on the interface of the organic and inorganic layers.
