Leadframe-type semiconductor packages that allow the semiconductor packages to be stacked on top of each other. One aspect of the semiconductor package includes a leadframe, a plurality of electrical connectors, a semiconductor chip, and a sealing material for encapsulating the above components. The leadframe has a plurality of leads, with each one of the plurality of leads running from the top of the semiconductor package to the bottom of the semiconductor package. Each one of the plurality of leads has a top portion protruding from the top surface of the semiconductor package and a bottom portion protruding from the top surface of the semiconductor package and a bottom portion protruding from the bottom surface of the semiconductor package. The leads allow for electrical connection of a second semiconductor package placed on top of the first semiconductor package. Further, the protruding parts of the leads form a space between the stacked semiconductor packages for improved heat dissipation.

摘要:
A die pick and place tool is used to pick up a semiconductor die and place it on a substrate. The die pick and place tool comprises a moving shaft, an adjustable bearing or an elastic element, and a pick-up head. The adjustable bearing or the elastic element is connected to the moving shaft. The pick-up head is connected to the adjustable bearing, and used to catch the semiconductor die. When the semiconductor die contacts the substrate, a counter force acts to the adjustable bearing to adjust the tilt level of the pick-up head.
