20090075427 | METHOD OF MANUFACTURING A SEMICONDUCTOR DEVICE - The quality of a non-leaded semiconductor device is to be improved. The semiconductor device comprises a sealing body for sealing a semiconductor chip with resin, a tab disposed in the interior of the sealing body, suspension leads for supporting the tab, plural leads having respective to-be-connected surfaces exposed to outer edge portions of a back surface of the sealing body, and plural wires for connecting pads formed on the semiconductor chip and the leads with each other. End portions of the suspending leads positioned in an outer periphery portion of the sealing body are not exposed to the back surface of the sealing body, but are covered with the sealing body. Therefore, stand-off portions of the suspending leads are not formed in resin molding. Accordingly, when cutting the suspending leads, corner portions of the back surface of the sealing body can be supported by a flat portion of a holder portion in a cutting die which flat portion has an area sufficiently wider than a cutting allowance of the suspending leads, whereby it is possible to prevent chipping of the resin and improve the quality of the semiconductor device (QFN). | 03-19-2009 |
20090189260 | SEMICONDUCTOR DEVICE - In a non-leaded type semiconductor device, a tab, tab suspension leads, and other leads are exposed to one surface of a seal member. A semiconductor element is positioned within the seal member and fixed to a surface of the tab with an adhesive. The tab is formed larger than the semiconductor element so that outer peripheral edges of the tab are positioned outside outer peripheral edges of the semiconductor element. A groove is formed in the tab surface portion positioned between the area to which the semiconductor element is fixed and wire connection areas to which the wires are connected, the groove being formed so as to surround the semiconductor element fixing area, thereby preventing peeling-off between the tab to which the semiconductor element is fixed and the resin which constitutes the package. | 07-30-2009 |
