20080217769 | SEMICONDUCTOR MODULE, METHOD OF MANUFACTURING SEMICONDUCTOR MODULE, AND MOBILE DEVICE - An electrode for a semiconductor device is formed on the mounting surface (particularly, the outer periphery thereof) of a semiconductor substrate in a semiconductor module. In order to secure a large gap between the electrodes, an insulating layer is formed on the electrode. Also formed are a plurality of bumps penetrating the insulating layer and connected to the electrode, and a rewiring pattern integrally formed with the bumps. The rewiring pattern includes a bump area and a wiring area extending contiguously with the bump area. | 09-11-2008 |
20090057903 | Semiconductor module, method for manufacturing semiconductor modules, semiconductor apparatus, method for manufacturing semiconductor apparatuses, and portable device - Cost is suppressed and a semiconductor module is made thinner. The semiconductor is of a structure where a semiconductor element is embedded in a recess formed in a wiring substrate. A substrate electrode provided around the recess and an element electrode are electrically connected through a wiring formed integrally with bumps. | 03-05-2009 |
20090115056 | DEVICE MOUNTING BOARD, SEMICONDUCTOR MODULE, AND MOBILE DEVICE - A device mounting board includes an insulating layer formed of an insulating resin, a glass cloth covering the surface of the insulating layer, and an electrode provided in a through hole extending through the glass cloth. The angle of contact with solder of the glass cloth is larger than that of the resin. Thus, solder bumps are formed on the electrode of the device mounting board | 05-07-2009 |
20090149034 | SEMICONDUCTOR MODULE AND METHOD OF MANUFACTURING THE SAME - In a semiconductor module, adhesion between an insulating base material and an insulator provided on the insulating base material, for example a sealing resin of the semiconductor element, is to be improved. | 06-11-2009 |
20090194322 | DEVICE MOUNTING BOARD AND MANUFACTURING METHOD THEREFOR, AND SEMICONDUCTOR MODULE - A device mounting board has a double-layer wiring structure where a first wiring layer and a second wiring layer are stacked together with an insulating layer held between the first and second wiring layers. The first wiring layer and the second wiring layer are electrically connected by way of a via conductor provided on a side wall of a through-hole that penetrates the insulating layer. The through-hole that penetrates the insulating layer has a stepped portion. The via conductor, provided along the insulating layer in the via conductor, has a step associated with the stepped portion of the via conductor. | 08-06-2009 |
20130181344 | SEMICONDUCTOR MODULE, METHOD FOR MANUFACTURING THE SEMICONDUCTOR MODULE, AND MOBILE APPARATUS - Bump electrodes and wiring layers are formed by selectively removing a copper sheet while the copper sheet is being held on a supporting base by an adhesion layer. Subsequently, a device mounting board is formed by laminating an insulating resin layer in such a manner that Au/Ni layers are exposed on the bump electrodes and the adhesion layer. The device mounting board and a semiconductor device held on the supporting base are temporarily press-bonded to each other and then the supporting base and the adhesion layer are removed. Then the device mounting board and the semiconductor device are finally and permanently press-bonded together. | 07-18-2013 |
