20090315190WIRING BOARD, SEMICONDUCTOR DEVICE USING WIRING BOARD AND THEIR MANUFACTURING METHODS - A wiring board has an insulating layer, a plurality of wiring layers formed in such a way as to be insulated from each other by the insulating layer, and a plurality of vias formed in the insulating layer to connect the wiring layers. Of the wiring layers, a surface wiring layer formed in one surface of the insulating layer include a first metal film exposed from the one surface and a second metal film embedded in the insulating layer and stacked on the first metal film. Edges of the first metal film project from edges of the second metal film in the direction in which the second metal film spreads. By designing the shape of the wiring layers embedded in the insulating layer in this manner, it is possible to obtain a highly reliable wiring board that can be effectively prevented from side etching in the manufacturing process and can adapt to miniaturization and highly dense packaging of wires.12-24-2009

20100258955SEMICONDUCTOR DEVICE AND METHOD OF MANUFACTURING THE SAME - The semiconductor device includes a substrate over one surface of which an electroless plating electrode film is formed; a semiconductor chip mounted over the one surface of the substrate; and a bonding wire which connects the semiconductor chip and one surface of the electroless plating electrode film, a recessed depth which is a difference between a lowermost height of a bonding portion of the one surface of the electroless plating electrode film to the bonding wire, and an uppermost height of the one surface other than the bonding portion being equal to or less than 1.5 μm.10-14-2010
20110049693SEMICONDUCTOR DEVICE, METHOD OF MANUFACTURING SEMICONDUCTOR DEVICE, AND LEAD FRAME THEREOF - A first semiconductor chip and a second semiconductor chip are overlapped with each other in a direction in which a first multilayer interconnect layer and a second multilayer interconnect layer are opposed to each other. When seen in a plan view, a first inductor and a second inductor are overlapped. The first semiconductor chip and the second semiconductor chip have non-opposed areas which are not opposed to each other. The first multilayer interconnect layer has a first external connection terminal in the non-opposed area, and the second multilayer interconnect layer has a second external connection terminal in the non-opposed area.03-03-2011
