20080293330 | Alumina-film-polishing composition and chemical mechanical polishing method using the same - An alumina-film-polishing composition is for use in chemical mechanical polishing of an object to be polished that includes an alumina film with an irregular surface, so as to planarize the irregular surface. The polishing composition contains an alumina abrasive grain, and a protection-film-forming agent for forming a protection film on the surface of each of the alumina film and the alumina abrasive grain. The protection-film-forming agent is a water-soluble polymer that has a weight average molecular weight within a range of 100 to 1,000,000 and that is obtained by polymerizing a monomer having at least one OH group or COOH group in its molecule. | 11-27-2008 |

20110132868 | Polishing composition for polishing silver and alumina, and polishing method using the same - An object to be polished includes a support body and a silver thin film. The support body has a surface to be polished and a trench that opens in the surface to be polished. At least part of the support body, including the surface to be polished, is made of alumina. The silver thin film is formed to fill the trench of the support body. A polishing composition is for use in a process of polishing the silver thin film and the surface to be polished of the object to be polished by chemical mechanical polishing. The polishing composition contains silica abrasive grains, nitric acid, hydrogen peroxide, and benzotriazole. The polishing composition is such one that the polishing rate of silver divided by the polishing rate of alumina in the process of polishing is equal to or higher than 5. | 06-09-2011 |
20130027810 | METHOD OF FORMING METAL TO A CONCAVE PORTION OF A SUBSTRATE, METHOD OF MANUFACTURING A MAGNETIC HEAD AND A MAGNETIC HEAD - The present invention relates to a method of forming a metal in a concave portion of a substrate. The method includes a step of preparing a substrate having a concave portion; a step of applying a liquid coating member on the substrate and filling in and solidifying the concave portion with the coating member; a step of covering the coating member with a resist; a step of forming a penetrating hole that penetrates the resist in a position of the concave portion of the substrate; a step of removing the coating member within the concave portion; and a step of filling a metal into a portion where the coating member has been removed. | 01-31-2013 |
20130062307 | METHOD OF MAKING A MASK, METHOD OF PATTERNING BY USING THIS MASK AND METHOD OF MANUFACTURING A MICRO-DEVICE - The present invention relates to a method of making a mask for patterning a thin film The method includes a step of forming an inorganic material, which is resolvable into alkali solution, on a substrate; a step of forming the inorganic material in a predetermined pattern; and a step of narrowing the inorganic material with the alkali solution to form the mask. | 03-14-2013 |
20130070364 | THIN FILM MAGNETIC HEAD AND MANUFACTURING METHOD THEREOF - A thin film magnetic head of the present invention is configured to include a main pole layer; a main pole direct junction magnetic layer that has an auxiliary pole layer and an auxiliary yoke layer, the main pole direct junction magnetic layer being directly joined to the main pole layer in a state where a recording gap layer is partially intervened near an air bearing surface (ABS) with respect to the main pole layer; and a first magnetic recording exciting coil that is buried between the auxiliary pole layer and the auxiliary yoke layer configuring the main magnetic direct junction magnetic layer with an insulating layer therebetween. Thereby, an effective magnetic path length can be shortened in order to improve the high-frequency characteristics, and furthermore, simplification of the manufacturing processes becomes possible. | 03-21-2013 |
