Wafer Level System Integration

The department "Wafer Level System Integration" (WLSI) develops advanced packaging and system integration technologies and offers customer-specific solutions for microelectronic products in the overall scope of smart system integration. Approx. 60 scientists work at two locations: Berlin and Dresden  (ASSID: All Silicon System Integration Dresden). WLSI is cooperating globally with manufacturers and users of microelectronic products as well as cleanroom equipment producers and material developers from the chemical industry.

The department WLSI has cleanrooms and laboratories with production-compatible equipment available at both sites. Beside the flexibility regarding the processing of different wafers sizes, both process lines are also  characterized by a high adaptability of the individual processes. The process line at ASSID is particularly tailored to realize production-related and industry-compatible development and processing.

Furthermore, in Berlin we have with our PhoxLab an independent and neutral platform for benchmarking and presentation of photonic components and solutions for various hirachy levels, architectures and protocols in data centers.
