Title: Manufacturing method of a shallow trench isolation structure
Inventor: HUANG JAU-YUAN
IPC: H01L21/76
Filed: 1998-09-18
Granted: 2000-06-21
Abstract: This is a manufacturing method of a shallow trench isolation structure. The polished particles in a slurry of the traditional manufacturing processes usually scratches the surface of the insulate layer and form micro-scratches. Since micro-scratches will affect the later manufacturing processes, therefore, the invention aims to improve the shortcomings the traditional shallow trench isolation structure. Through chemical mechanical polishing and additional densification process, the texture of the insulating plug will become denser. This makes the insulate plug more resistible to against the hydrofluoric acid and the etch-back of the micro-scratches on the insulate plug. This invention can improve the traditional manufacturing method of shallow trench isolation structure and solve the short-circuit problem caused by the micro-scratches.

Title: Sintered electrode for solid oxide fuel cells
Inventor: RUKA ROSWELL J
IPC: H01M8/12
Filed: 1998-09-22
Granted: 2000-02-21
Abstract: A solid oxide fuel cell fuel electrode is produced by a sintering process. An underlayer is applied to the electrolyte of a solid oxide fuel cell in the form of a slurry, which is then dried. An overlayer is applied to the underlayer and then dried. The dried underlayer and overlayer are then sintered to form a fuel electrode. Both the underlayer and the overlayer comprise a combination of electrode metal such as nickel, and stabilized zirconia such as yttria-stabilized zirconia, with the overlayer comprising a greater percentage of electrode metal. The use of more stabilized zirconia in the underlayer provides good adhesion to the electrolyte of the fuel cell, while the use of more electrode metal in the overlayer provides good electrical conductivity. The sintered fuel electrode is less expensive to produce compared with conventional electrodes made by electrochemical vapor deposition processes. The sintered electrodes exhibit favorable performance characteristics, including good porosity, adhesion, electrical conductivity and freedom from degradation.
