Filed:

Sep 30, 1999

Appl. No.:

09/409120

Inventors:

David B. Beach - Knoxville TN
Jonathan S. Morrell - Knoxville TN
Mariappan Paranthaman - Knoxville TN
Thomas Chirayil - Knoxville TN
Eliot D. Specht - Knoxville TN
Amit Goyal - Knoxville TN

Assignee:

UT-Battelle, LLC - Oak Ridge TN

International Classification:

C30B 2802

US Classification:

117 9, 4271263, 4271264, 4273764, 4274192, 4274193, 428469, 428701, 428702, 428699

Abstract:

A laminate article comprises a substrate and a biaxially textured (RE RE ) O buffer layer over the substrate, wherein 0x1 and RE and RE are each selected from the group consisting of Nd, Sm, Eu, Ho, Er, Lu, Gd, Tb, Dy, Tm, and Yb. The (RE RE ) O buffer layer can be deposited using sol-gel or metal-organic decomposition. The laminate article can include a layer of YBCO over the (RE RE ) O buffer layer. A layer of CeO between the YBCO layer and the (RE RE ) O buffer can also be include. Further included can be a layer of YSZ between the CeO layer and the (RE RE ) O buffer layer. The substrate can be a biaxially textured metal, such as nickel. A method of forming the laminate article is also disclosed.

Filed:

Nov 29, 1994

Appl. No.:

8/346436

Inventors:

David B. Beach - Knoxville TN
Alfred Grill - White Plains NY
Christopher J. Smart - Wappingers Falls NY

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H01G 438

US Classification:

361328

Abstract:

A storage capacitor having high dielectric constant materials and a method for forming same are described. The method solves the problems associated with fabrication of planar capacitors for DRAM chips constructed from inorganic oxides with perovskite structure. These materials are not readily etched by conventional ion etching techniques. These materials also react with silicon and silicon dioxide and the disclosed process avoids these interactions.
