| 20080277155 | Wiring substrate and method of manufacturing the same - In a method of manufacturing a wiring substrate of the present invention, a through-hole plating layer is formed from an inner surface of a through hole in a substrate to both surface sides, then a resin is filled in a through hole, and then a first resist in which an opening portion is provided on the through hole is formed. Then, a partial cover plating layer is formed in the opening portion in the first resist, then the first resist is removed, and then a second resist that covers a whole of the partial cover plating layer and has a pattern for patterning the through-hole plating layer is formed. Then, a pad wiring portion containing the partial cover plating layer and a wiring pattern are obtained by etching the through-hole plating layer while using the second resist as a mask. | 11-13-2008 |
| 20090211798 | PGA TYPE WIRING BOARD AND METHOD OF MANUFACTURING THE SAME - A PGA type wiring board includes a wiring board to which a head portion of a pin is joined to a pad portion with solder interposed therebetween, and a pin fixing plate having a through hole formed therein through which a shank portion of the pin is inserted, and having an adhesive layer formed on one surface thereof. The pin fixing plate is bonded to the wiring board with the adhesive layer interposed therebetween while the shank portion of the pin is inserted through the through hole. The through hole is shaped in a stepped form with a two-step configuration when viewed in cross section. | 08-27-2009 |
| 20100065959 | SEMICONDUCTOR PACKAGE AND METHOD OF MANUFACTURING THE SAME, AND SEMICONDUCTOR DEVICE - A semiconductor package includes a wiring substrate having a connection pad on both surface sides respectively, and a supporting plate provided on one surface side of the wiring substrate and formed of an insulator in which an opening portion is provided in a portion corresponding to the connection pad. The external connection terminals (the lead pins, or the like) are provided on the connection pads on the surface of the wiring substrate on which the supporting plate is provided, and the semiconductor chip is mounted on the connection pads on the opposite surface. | 03-18-2010 |
| 20100175917 | WIRING BOARD AND METHOD OF MANUFACTURING THE SAME - A wiring board (package) has a structure in which multiple wiring layers are stacked one on top of another with insulating layers each interposed between corresponding two of the wiring layers, and the wiring layers are connected to one another through vias formed in each of the insulating layers. In a peripheral region of the package, reinforcing patterns are provided on the same surfaces where the corresponding wiring layers are provided, respectively. Each of the reinforcing patterns is formed of a conductive layer formed on the same surface where the corresponding one of the wiring layers is provided, and is provided in an intermittent ring-like shape when viewed in a planar view. | 07-15-2010 |

| 20090095518 | WIRING BOARD AND METHOD OF MANUFACTURING THE SAME - A wiring board has a wiring member, a first reinforcing member and a second reinforcing member. The wiring member has wiring layers and insulating layers which are stacked, and the wiring layers include a first connecting electrode formed on a surface of the wiring member and a second connecting electrode formed on a back surface of the wiring member. A pin is formed on the second connecting electrode. The second reinforcing member is formed by a resin and serves to reinforce the wiring member. The first reinforcing member is formed on the whole back surface of the wiring member except for the pin provided on the second connecting electrode. | 04-16-2009 |

| 20090206470 | SEMICONDUCTOR DEVICE MANUFACTURING METHOD, SEMICONDUCTOR DEVICE, AND WIRING BOARD - In a semiconductor device manufacturing method, a semiconductor chip is mounted on a support board so as to expose a side of the semiconductor chip on which a plurality of terminal electrodes are provided. An insulating layer is formed so as to cover the side of the semiconductor chip on which the terminal electrodes are provided. Through electrodes connecting to the terminal electrodes and piercing the insulating layer are formed. Metal wirings connecting to the through electrodes are formed on the insulating layer. External terminal electrodes connecting the metal wiring are formed. Second spacing, spacing between the adjacent external terminal electrodes, is larger than first spacing, spacing between the adjacent terminal electrodes. | 08-20-2009 |
| 20090288873 | WIRING BOARD AND METHOD OF MANUFACTURING THE SAME - A wiring board is provided. The wiring board includes: a resin substrate having a through-hole therethrough; metal foil patterns formed on the resin substrate; and a first wiring layer formed on the metal foil patterns and on an inner surface of the through-hole, wherein the first wiring layer includes: a first power feeding layer; and a first plated layer laminated on the first power feeding layer; a resin member filled in the through-hole and between adjacent wiring patterns of the first wiring layer, wherein an end surface of the resin member is flush with a surface of the first wiring layer; and a second wiring layer formed on the surface of the first wiring layer and formed to cover an end surface of the through-hole, wherein the second wiring layer includes: a second power feeding layer; and a second plated layer laminated on the second power feeding layer. | 11-26-2009 |
