## Title
Method of manufacturing semiconductor devices

## Abstract

A method of manufacturing a semiconductor device. The method includes providing a metal carrier, attaching chips to the carrier, and applying a metal layer over the chips and the metal carrier to electrically couple the chips to the metal carrier. The metal carrier is segmented, after applying the metal layer, to obtain metal contact elements.

## Background
BACKGROUND
Electronic packaging continues to evolve and impact the electronics industry. The trend toward smaller, lighter, and thinner consumer products requires further packaging improvements. Surface-mount technology (SMT) and ball grid array (BGA) packages allow reduction of pad pitch on the printed circuit board. Chip-scale or chip-size packaging (CSP) includes packages having areas that are little more than the original die area. Wafer-level packaging (WLP) and lead-frame-based CSP are types of CSP.
WLP refers to packaging an integrated circuit at wafer level, instead of assembling the package of each individual unit after wafer dicing. WLP extends the wafer fabrication process to include device connection and device protection processes. Often, in WLP a completely packaged wafer is burned-in and tested after the final packaging step, such that tests before packaging are no longer necessary.
Lead-frame-based CSP refers to packaging semiconductor chips at a lead-frame array packaging level, instead of the traditional process of packaging semiconductor chips one at a time. Lead-frame-based CSP uses wafer level fabrication processes for connecting and protecting devices, which reduces packaging time, inventory and costs.
For these and other reasons, there is a need for the present invention.
SUMMARY
One embodiment described in the disclosure provides a method of manufacturing a semiconductor device. The method includes providing a metal carrier, attaching chips to the carrier, and applying a metal layer over the chips and the metal carrier to electrically couple the chips to the metal carrier. The metal carrier is segmented, after applying the metal layer, to obtain metal contact elements.

20. A method of manufacturing a semiconductor device, comprising:
providing a metal carrier;
attaching chips to the metal carrier, such that bottoms of the chips are directly connected to metal of the metal carrier;
applying an insulating layer over the chips and the metal carrier, such that the insulating layer covers the metal carrier and tops and sides of the chips;
structuring the insulating layer to expose portions of the tops of the chips and first portions of the metal carrier;
applying a metal layer over the chips and the metal carrier and the insulating layer to electrically couple exposed portions of the tops of the chips to exposed first portions of the metal carrier, wherein the insulating layer is situated between the metal layer and the sides of the chips and between the metal layer and second portions of the metal carrier; and
segmenting the metal carrier, after applying the metal layer, to obtain metal contact elements, wherein segmenting the metal carrier includes removing third portions of the metal carrier to expose the insulating layer and the metal layer.
