| 20080290505 | MOLD DESIGN AND SEMICONDUCTOR PACKAGE - A chip package includes a carrier having a first and a second major surface. The first major surface includes an active region surrounded by an inactive region. The chip package includes contact pads in the active region for mating with chip contacts of a chip. A support structure is disposed on the inactive region of the first major surface. The support structure forms a dam that surrounds the active region. When a chip or chip stack is mounted in the active region, spacing exists between the dam and the chip or chip stack. The spacing creates convention paths for heat dissipation. | 11-27-2008 |
| 20080303031 | VENTED DIE AND PACKAGE - A die that includes a substrate having a first and second major surface is disclosed. The die has at least one unfilled through via passing through the major surfaces of the substrate. The unfilled through via serves as a vent to release pressure generated during assembly. | 12-11-2008 |
| 20080303163 | THROUGH SILICON VIA DIES AND PACKAGES - A method for preparing a die for packaging is disclosed. A die having first and second major surfaces is provided. Vias and a mask layer are formed on the first major surface of the die. The mask includes mask openings that expose the vias. The mask openings are filled with a conductive material. The method includes reflowing to at least partially fill the vias and contact openings to form via contacts in the vias and surface contacts in the mask openings. | 12-11-2008 |
| 20100013081 | PACKAGING STRUCTURAL MEMBER - A structural member for use in semiconductor packaging is disclosed. The structural member includes a plurality of packaging regions to facilitate packaging dies in, for example, a wafer format. A packaging region has a die attach region surrounded by a peripheral region. A die is attached to the die attach region. In one aspect, the die attach region has opening through the surfaces of the structural member for accommodating a die. Through-vias disposed are in the peripheral regions. The structural member reduces warpage that can occur during curing of the mold compound used in encapsulating the dies. In another aspect, the die attach region does not have an opening. In such cases, the structural member serves as an interposer between the die and a substrate. | 01-21-2010 |
| 20100109142 | INTERPOSER FOR SEMICONDUCTOR PACKAGE - An interposer is presented. The interposer includes an interposer base having first and second surfaces. A redistribution layer is disposed on a first surface of the interposer base. The interposer has at least one interposer pad coupled to the redistribution layer. It also includes at least one interposer contact on the second surface. The interposer contact is electrically coupled to the interposer pad via the redistribution layer. The interposer also includes at least one interposer via through the interposer base for coupling the interposer contact to the redistribution layer. The interposer via includes reflowed conductive material of the interposer contact. | 05-06-2010 |
| 20100109169 | SEMICONDUCTOR PACKAGE AND METHOD OF MAKING THE SAME - A stiffener is provided for use in making semiconductor devices. The stiffener and method of use provided prevent or reduce warpage of a semiconductor package during the assembly process. More particularly, the stiffener functions to prevent or reduce warpage during molding of an assembly of wafers and/or dies. The stiffener may be positioned above the backside or non-active side of an assembly of wafer and/or dies during molding. The presence of the stiffener prevents or reduces warpage caused by CTE mismatch between the mold material and the wafer and/or under the high temperatures encountered in the process of molding. After molding, the stiffener may continue to provide support to the assembly. | 05-06-2010 |
| 20100261313 | SEMICONDUCTOR PACKAGE AND METHOD OF PACKAGING SEMICONDUCTOR DEVICES - A method of forming a device stack is presented. The method includes providing a temporary substrate having a temporary mounting surface. A first chip is temporarily mounted to the temporary mounting surface. A first bottom surface of the first chip is temporarily mounted to the temporary mounting surface and a first top surface of the first chip comprises first interconnects. A second chip is stacked on the first chip. The second chip includes second conductive contacts on the second bottom surface. The method also includes bonding the first and second chips together to form the device stack. The second conductive contacts are coupled to the first interconnects. The first bottom surface of the first chip is separated from the substrate to separate the chip stack from the substrate. | 10-14-2010 |
| 20120018869 | MOLD DESIGN AND SEMICONDUCTOR PACKAGE - A chip package includes a carrier having a first and a second major surface. The first major surface includes an active region surrounded by an inactive region. The chip package includes contact pads in the active region for mating with chip contacts of a chip. A support structure is disposed on the inactive region of the first major surface. The support structure forms a dam that surrounds the active region. When a chip or chip stack is mounted in the active region, spacing exists between the dam and the chip or chip stack. The spacing creates convention paths for heat dissipation. | 01-26-2012 |
