| Number | Title | Issue Date |
| 7510093 | Method of manufacturing a wiring substrate, method of manufacturing an electro-optical device, method of manufacturing an electronic apparatus An etching method of the invention includes arranging droplets including a film-forming material on a substrate, drying each of the droplets to form a dry film having a width smaller than the diameter of each droplet at the time of the arrangement, and performing et... | 03/31/2009 |
| 7066344 | Mask film, its manufacturing method, and manufacturing method of circuit board using the same A mask film includes a base material, a parting layer and a non-parting portion placed on the base material. Accordingly, an optimum adhesion strength of the mask film and a prepreg sheet can be maintained, and peeling between the mask film and prepreg sheet can be ... | 06/27/2006 |
| 7034231 | Method for the manufacture of printed circuit boards with plated resistors A process is revealed whereby resistors can be manufactured integral with a printed circuit board by plating the resistors onto the insulative substrate. Uniformization of the insulative substrate through etching and oxidation of the plated resistor are discussed as... | 04/25/2006 |
| 6989105 | Detection of hardmask removal using a selective etch A method of creating electrical shorts within an interconnection structure, using a selective etch, to detect a region that is missing a protective hardmask in order to prevent future use of the defective device. ... | 01/24/2006 |
| 5914150 | Formation of polycarbonate film with apertures determined by etching charged-particle tracks A technique for creating openings in a polycarbonate film entails providing a liquid chemical formulation that contains polycarbonate material, a liquid that dissolves the polycarbonate, and possibly one or more other constituents. The liquid is typically... | 06/22/1999 |
