Patent number: 7105059Abstract: A reaction apparatus for atomic layer deposition includes a vacuum chamber having a gas inlet, a gas outlet, and a gas flow path for connecting the gas inlet and the gas outlet; a reactor located in the vacuum chamber, including a reaction chamber where a first gas, which is input through the gas flow path, reacts with a specimen in the reaction chamber, the reactor further including a gas distributor, which is located in the reaction chamber to evenly supply the gas; a specimen location controller for moving the specimen located in the vacuum chamber to the reaction chamber; and an analyzer, which is connected to the reaction chamber, for analyzing a second gas generated in the reaction chamber. The apparatus is able to deposit uniform atomic layers on a specimen by maintaining the pressure and flow of reactant gas and can deposit and analyze an atomic layer simultaneously.Type: GrantFiled: June 20, 2003Date of Patent: September 12, 2006Assignee: Samsung Electronics Co., Ltd.Inventors: Jae-cheol Lee, Chang-bin Lim, Kwi-young Han

Publication number: 20040266011Abstract: Provided is an in-situ analysis method for an atomic layer deposition (ALD) process. The provided method includes transferring a substrate to a reaction chamber in a vacuum container, depositing an atomic layer on the upper surface of the substrate, and analyzing the state of the atomic layer to determine the quality of the atomic layer in real time. Using the method decreases failure and the cost for additional analysis.Type: ApplicationFiled: June 24, 2004Publication date: December 30, 2004Applicant: Samsung Electronics Co., Ltd.Inventors: Jae-cheol Lee, Chang-bin Lim, Ran-ju Jung
