Ams builds analogue 3D IC line in Austria

Keywords:Ams  3D IC production  TSV  through-silicon via  wafer fabrication 

Ams AG has invested about Rs.207.55 crore ($33 million) to create dedicated 3D IC production capacity at its wafer fabrication plant near Graz, Austria. The investment provides for the installation of new 3D IC equipment in clean room space available at the plant, situated at the company's headquarters.

The additional production capacity comes in response to a surge in demand outlook for ICs fabricated with 3D IC integration technology developed exclusively by Ams. The patented technology enables the design and production of radically improved IC packages that are smaller and offer better device performance than existing packages.

For instance, the through-silicon via (TSV) interconnects in 3D ICs from Ams can replace the bond wires in conventional single-die devices. For optical semiconductors, clear packaging requirements are eliminated to enable production of chipscale packages that are smaller, cheaper and less vulnerable to EMI.

The Ams 3D IC process also enables the production of stacked-die devices. Two die produced in different processes (such as a photodiode die and a silicon signal-processing die) are bonded back-to-back to produce a monolithic stacked-die device. This can replace two separate packages, has a far smaller footprint, and features much shorter interconnects, resulting in improved performance and reduced electrical noise.

The new equipment line, which will be fully operational by the end of 2013, will be available for production of 3D ICs for any Ams product or full-service foundry customer. Initially the line will produce devices for customers in the medical imaging and mobile phone markets.
