Abstract:
A semiconductor package includes a leadframe having first and second level downset lead extensions, a quad flat nonleaded package (QFN) attached to the first level downset lead extension, and a flip chip die attached to the second level downset lead extension. Another embodiment of a semiconductor package includes a leadframe having a lead, a first quad flat nonleaded package (QFN) connected to the lead, and a second quad flat nonleaded package invertly connected to a top surface of the first quad flat nonleaded package, wherein the second quad flat nonleaded package is wirebonded to the lead. A third embodiment of a semiconductor package includes a leadframe having a lead with a first level downset lead extension, a quad flat nonleaded package (QFN) connected to the first level downset lead extension, and a first wirebondable die attached to a top or bottom surface of the quad flat nonleaded package.
