Patent number: 8435336Abstract: A deoxidizer includes a porous body of fluorite-type cerium oxide represented by CeOx (where x is a positive number smaller than 2) and having a reversible oxygen deficiency. The deoxidizer has a specific surface area of 0.6 to 1.8 m2/g and a pore median diameter of 1.6 to 5.3 ?m. The cerium oxide used for the deoxidizer is produced by: firing a cerium-containing salt in the atmosphere at 500° C. to 1400° C. for 1 to 20 hours, to produce fluorite-type cerium oxide composed of a porous body; and firing the cerium oxide at 700° C. to 1100° C. for 1 to 3 hours in a reducing atmosphere having a hydrogen concentration equal to or above the lower explosive limit, to remove oxygen from the cerium oxide and produce the fluorite-type cerium oxide represented by CeOx and having a reversible oxygen deficiency.Type: GrantFiled: July 6, 2009Date of Patent: May 7, 2013Assignee: Mitsui Mining & Smelting Co., Ltd.Inventors: Kazuya Kinoshita, Yuichi Senoo, Yousuke Shibata, Isamu Yashima

Publication number: 20130109147Abstract: Some embodiments include methods of forming memory cells. Metal oxide may be deposited over a first electrode, with the deposited metal oxide having a relatively low degree of crystallinity. The degree of crystallinity within the metal oxide may be increased after the deposition of the metal oxide. A dielectric material may be formed over the metal oxide, and a second electrode may be formed over the dielectric material. The degree of crystallinity may be increased with a thermal treatment. The thermal treatment may be conducted before, during, and/or after formation of the dielectric material.Type: ApplicationFiled: October 26, 2011Publication date: May 2, 2013Applicant: MICRON TECHNOLOGY, INC.Inventors: Noel Rocklein, D.V.
