Patent number: 8962466Abstract: A metal oxide formed by in situ oxidation assisted by radiation induced photo-acid is described. The method includes depositing a photosensitive material over a metal surface of an electrode. Upon exposure to radiation (for example ultraviolet light), a component, such as a photo-acid generator, of the photosensitive material forms an oxidizing reactant, such as a photo acid, which causes oxidation of the metal at the metal surface. As a result of the oxidation, a layer of metal oxide is formed. The photosensitive material can then be removed, and subsequent elements of the component can be formed in contact with the metal oxide layer. The metal oxide can be a transition metal oxide by oxidation of a transition metal. The metal oxide layer can be applied as a memory element in a programmable resistance memory cell. The metal oxide can be an element of a programmable metallization cell.Type: GrantFiled: May 15, 2013Date of Patent: February 24, 2015Assignee: Macronix International Co., Ltd.Inventors: Feng-Min Lee, Erh-Kun Lai, Wei-Chih Chien, Ming-Hsiu Lee, Chih-Chieh Yu

Publication number: 20130125815Abstract: A plasma enhanced atomic layer deposition (PEALD) system used to form thin films on substrates includes a plasma chamber, a processing chamber, two or more ring units and a control piece. The plasma chamber includes an outer and an inner quartz tubular units, whose central axes are aligned with each other. Therefore, plasma is held and concentrated in a cylindrical space formed between the outer and outer quartz tubular units.
