Abstract

The invention relates to a semiconductor sealing and stacking combination structure with movable external terminals, which mainly comprises a plurality of semiconductor sealing parts which are mutually stacked and a plurality of electrical connection components such as welding fluid so as to connect the external terminals of the semiconductor sealing parts such as outer leads of a lead frame. Eachsemiconductor sealing part seals at least one wafer by a sealing body, and the sealing body can move toward these electrical connection components so as to absorb stress among the semiconductor sealing parts. A stress relief layer can be formed among the semiconductor sealing parts in one embodiment.

Description

Technical field [0001] The present invention relates to a semiconductor package stack combination structure (POP device), and more particularly to a semiconductor package stack combination structure with movable external terminals. Background technique [0002] In recent years, high-tech electronic products have continuously introduced more user-friendly and better-function electronic products, resulting in the trend of lighter, thinner, shorter and smaller products. Therefore, a type of semiconductor device assembly is a vertical 3D stack of multiple semiconductor packages to meet the requirements of small surface bonding area and high-density device placement, which is called a POP device. Among them, the stackable semiconductor package component uses the lead frame as the chip carrier, and the cost is the lowest. It is welded and stacked to connect the external pins of the component (encapsulation body) to achieve the circuit series connection, but the external pins The solde...
