| 20080198568 | Dual-sided substrate integrated circuit package including a leadframe having leads with increased thickness - An integrated circuit package includes a first non-conductive substrate having a first inner surface and a second non-conductive substrate having a second inner surface. A die having a first thickness is disposed between the first and second inner surfaces. A leadframe includes a member having a proximal end and a distal end. The proximal end has a second thickness less than the first thickness. The distal end is disposed between the first and second inner surfaces. The distal end is undulated such that the distal end has an effective thickness greater than the second thickness. | 08-21-2008 |
| 20090001546 | Ultra-thick thick film on ceramic substrate - An electrically isolated and thermally conductive double-sided pre-packaged integrated circuit component exhibiting excellent heat dissipative properties, durability and strength, and which can be manufactured at a low cost includes electrically insulated and thermally conductive substrate members having outer surfaces, ultra-thick thick film materials secured to the outer surfaces of the substrate members and a lead member and a transistor member positioned between the substrate members. | 01-01-2009 |
| 20090057853 | Semiconductor power module with flexible circuit leadframe - A semiconductor power module includes a semiconductor chip thermally interfaced to a ceramic substrate and a leadframe defined by a flexible circuit disposed intermediate the chip and the ceramic substrate. The flexible circuit includes a conductor layer that is selectively encased in an insulated jacket to ensure adequate electrical insulation between the conductor layer and adjacent conductive surfaces. Preferably, the module is constructed for double side cooling by sandwiching the chip between a pair of ceramic substrates and providing intermediate flexible circuit leadframes on both sides of the chip for electrically accessing the chip terminals. | 03-05-2009 |
| 20090057882 | Fluid cooled semiconductor power module having double-sided cooling - A semiconductor power module includes one or more power semiconductor power devices sandwiched between a fluid conducting base and a fluid conducting cover joined to the base. Fluid coolant entering the base diverges into a first flow path through the base and a second parallel flow path through the cover, and then converges and discharges through an outlet. The semiconductor devices have upper and lower active areas that are thermally coupled to inboard faces of the cover and base for low double-sided thermal resistance, and the devices are electrically accessed through a set of terminals formed on the base. Multiple sets of semiconductor power devices are double-side cooled by joining multiple fluid conducting covers to the base such that the coolant successively diverges and then re-converges at the locations where each cover is joined to the base. Preferably, the flow paths in both the base and cover include integral features for enhancing the surface area in contact with the coolant. | 03-05-2009 |
| 20100133672 | DUAL-SIDED SUBSTATE INTEGRATED CIRCUIT PACKAGE INCLUDING A LEADFRAME HAVING LEADS WITH INCREASED THICKNESS - An integrated circuit package includes a first non-conductive substrate having a first inner surface and a second non-conductive substrate having a second inner surface. A die having a first thickness is disposed between the first and second inner surfaces. A leadframe includes a member having a proximal end and a distal end. The proximal end has a second thickness less than the first thickness. The distal end is disposed between the first and second inner surfaces. The distal end is undulated such that the distal end has an effective thickness greater than the second thickness. | 06-03-2010 |
