20100244228 | Semiconductor device and method of manufacturing the same - The extent of a bow of a semiconductor device is suppressed in a case where the fillet width of an underfill resin is asymmetrical. The center position | 09-30-2010 |
20110084384 | SEMICONDUCTOR DEVICE AND METHOD FOR MANUFACTURING THE SAME - A semiconductor device includes a substrate, a semiconductor chip that is bonded to one of the faces of the substrate via bumps, and has a device formation face facing the one of the faces, and a resin that fills the space between the device formation face of the semiconductor chip and the one of the faces of the substrate. The resin includes: a first resin that is formed in a formation region of bumps placed on the outermost circumference of the bumps, and is formed inside the formation region, and a second resin that is formed outside the first resin. The thermal expansion coefficient of the substrate is higher than the thermal expansion coefficient of the first resin. The thermal expansion coefficient of the second resin is higher than the thermal expansion coefficient of the first resin. | 04-14-2011 |
20120238060 | SEMICONDUCTOR DEVICE AND METHOD OF MANUFACTURING THE SAME - A method of manufacturing a semiconductor device, includes mounting a semiconductor chip on a wiring substrate such that one surface of the semiconductor chip is faced to one surface of the wiring substrate, and filling a first resin in a gap between the surface of the wiring substrate and the surface of the semiconductor chip such that part of the first resin protrudes from the gap. In the filling of the first resin, the first resin is injected into the gap by use of a first resin injection nozzle while the first resin injection nozzle is being moved along any one of sides of the semiconductor chip or along two sides of the semiconductor chip which are adjacent to each other. | 09-20-2012 |
20140361430 | SEMICONDUCTOR DEVICE - A semiconductor chip and a wiring board are coupled to each other through conductor posts. The centers of conductor posts situated above openings at the outermost periphery shift from the centers of the openings in a direction away from the center of the semiconductor chip. When a region where each of the conductor posts and an insulating layer are overlapped with each other is designated as an overlapped region, the width of the overlapped region more on the inner side than the opening is smaller than the width of the overlapped region more on the outer side than the opening. Thus, while stress applied to the conductor posts is relaxed, coupling reliability between the semiconductor chip and the wiring board is retained. | 12-11-2014 |
20150179615 | SEMICONDUCTOR DEVICE AND METHOD FOR MANUFACTURING THE SAME - To improve reliability of a semiconductor device. In a conductive material that electrically couples a Cu pillar electrode and a lead, an alloy part comprised of an alloy of tin and copper is formed inside this conductive material. At this time, the alloy part contacts both the Cu pillar electrode and the lead, and the Cu pillar electrode and the lead are bound through the alloy part. Similarly, also in FIG. | 06-25-2015 |

20150236003 | METHOD OF MANUFACTURING SEMICONDUCTOR DEVICE - A method of manufacturing a semiconductor device obtained by laminating a first semiconductor chip and a second semiconductor chip with different planar sizes when seen in a plan view on a wiring board via an adhesive material, in which the second semiconductor chip with a relatively larger planar size is mounted on the first semiconductor chip with a relatively smaller planar size. Also, after the first and second semiconductor chips are mounted, the first and second semiconductor chips are sealed with resin. Here, before sealing with the resin, a gap between the second semiconductor chip and the wiring board is previously sealed with the adhesive material used when the first and second semiconductor chips are mounted. | 08-20-2015 |
