A packaging method for segregating die paddles of a leadframe, includes (a) providing a leadframe having a top surface, a bottom surface and a die paddle region, the die paddle region having a plurality of die paddles, wherein at least two of the die paddles are connected to each other by at least one connecting bar; (b) attaching a plurality of dies onto the die paddles; (c) forming a molding compound to encapsulate the dies on the die paddles, and exposing the bottom surface of the connecting bar outside the molding compound; and (d) removing part of the connecting bar so as to segregate the die paddles. The die paddles are thus rendered stable during the steps of die attaching, wire bonding and molding, and the yield is raised.

Packaging method for segregating die paddles of a leadframe

A semiconductor package includes a semiconductor chip electrically connected to a plurality of leads arranged at the periphery of the semiconductor chip wherein each of the leads is bent to have a first portion exposed from the upper surface of the semiconductor package and a second portion exposed from the lower surface of the semiconductor package. Both of the first portion and the second portion of each lead can be utilized for making external electrical connection.

Semiconductor package and stack arrangement thereof

A stacked package structure and a method for manufacturing the same are disclosed. The package structure comprises: a substrate having a first surface and a second surface in opposition to each other; at least one chip deposed on and electrically connected to the first surface of the substrate; a plurality of electrical connection devices deposed on the first surface and periphery of the substrate, wherein each electrical connection device is higher than the at least one chip in altitude; and an encapsulant covering the first surface of the substrate, the at least one chip and the electrical connection devices, wherein a top end of each electrical connection device is exposed at a surface of the encapsulant.
