Patent number: 7208821Abstract: A multichip package has a leadframe including peripheral leads arranged about a centrally situated die paddle. A first (“upper”) die is attached to a first (“top”) side of the leadframe die paddle, which can be generally flat. The second (“bottom”) side of the leadframe is partially-cut away (such as by partial etching), so that an outer part of the die paddle is thinner, and so that an inner part of the leads is thinner. These partially cutaway portions in the second (“bottom”) side of the leadframe provide a cavity, in which a second (“lower”) die is attached active side upward. The lower die may have bond pads situated near the center of the active surface, and electrical interconnection of the lower die may be made by wire bonds running through the gap between the die paddle and the leads; or, the lower die may be attached, and electrically interconnected, by flip chip interconnect to the die attach side of the cavity in the leadframe.Type: GrantFiled: October 17, 2005Date of Patent: April 24, 2007Assignee: ChipPAC, Inc.Inventors: Jongwoo Ha, Taebok Jung

Patent number: 7208827Abstract: A semiconductor component package configuration includes a semiconductor chip mounted to a printed circuit board, and a substrate arranged between the semiconductor chip and the printed circuit board. The substrate is for routing the wiring terminals of the semiconductor chip to the printed circuit board. The substrate is connected to the printed circuit board by solder joints. A filler between the semiconductor chip and the substrate mechanically isolates the semiconductor chip and the solder joints. A metal layer, which is connected to solder joints, is applied to the substrate. At least one molded element of heat-dissipating material is applied to the metal layer and is connected in a heat-conducting manner to the metal layer. This provides the package configuration with an improved capability of conducting the lost power that is dissipated from the installed semiconductor chip, and the desired mechanical properties of the package arrangement are retained.Type: GrantFiled: December 13, 2000Date of Patent: April 24, 2007Assignee: Infineon Technologies AGInventors: Christian Hauser, Simon Muff, Jens Pohl, Friedrich Wanninger
