20090001552 | SEMICONDUCTOR PACKAGE HAVING THROUGH HOLES FOR MOLDING BACK SIDE OF PACKAGE - A portable memory card and methods of manufacturing same are disclosed. The portable memory includes a substrate having a plurality of holes formed therein. During the encapsulation process, mold compound flows over the top surface of the substrate, through the holes, and down into a recessed section formed in the bottom mold cap plate to form a projection of mold compound on the bottom surface of the substrate. | 01-01-2009 |
20090001610 | SEMICONDUCTOR DIE HAVING A REDISTRIBUTION LAYER - A semiconductor device having a redistribution layer, and methods of forming same, are disclosed. After fabrication of semiconductor die on a wafer, a tape assembly is applied onto a surface of the wafer, in contact with the surfaces of each semiconductor die on the wafer. The tape assembly includes a backgrind tape as a base layer, and a film assembly adhered to the backgrind tape. The film assembly in turn includes an adhesive film on which is deposited a thin layer of conductive material. The redistribution layer pattern is traced into the tape assembly, using for example a laser. Thereafter, the unheated portions of the tape assembly may be removed, leaving the heated redistribution layer pattern on each semiconductor die. | 01-01-2009 |

20090085231 | METHOD OF REDUCING MEMORY CARD EDGE ROUGHNESS BY PARTICLE BLASTING - A method of forming a semiconductor package with smooth edges, and a semiconductor package formed thereby is disclosed. In embodiments, after encapsulation, a panel of semiconductor packages may undergo a first cutting process which cuts the curvilinear edges of the packages. Next, the partially singulated panel of packages may undergo an abrasion process for smoothing the cut curvilinear edges. The abrasion process may occur by forcing abrasive particles over the jagged side edges of a semiconductor package as a result of a pressure differential above and below the semiconductor packages. Upon completion of the abrasive process, a second cutting process may be performed which cuts along straight edges and singulates the respective packages from the panel. | 04-02-2009 |
20100052155 | METHODS OF PROMOTING ADHESION BETWEEN TRANSFER MOLDED IC PACKAGES AND INJECTION MOLDED PLASTICS FOR CREATING OVER-MOLDED MEMORY CARDS - A flash memory card and methods of manufacturing same are disclosed. The card includes a semiconductor package fabricated to receive a single-sided or double-sided lid. A surface of the semiconductor package may be formed with holes, trenches and/or pockmarks. After the holes, trenches and/or pockmarks are formed, a lid may be attached to the package surface in an injection molding process. During the injection molding process, the molten plastic flows into the holes, trenches and/or pockmarks to interconnect with the surface of the semiconductor package. Thus, when the molten plastic hardens, the holes, trenches and/or pockmarks ensure that the lid remains firmly attached to semiconductor package. | 03-04-2010 |
