WSG: Heterogeneous Integration and Advanced Packaging for mm-Wave and Sub-THz Circuits and Systems

Presentation Abstract
The ever-increasing demand for high-throughput communication links and high-resolution radar sensors is driving the development of future wireless systems at higher operating frequencies, from mm-wave to sub-THz bands. The flexibility required from these systems to support multiple functionalities leads to the adoption of large phased array antennas and complex System-in-Package (SiP) Bit-to-RF or Optical-to-RF solutions. Heterogeneous technologies and vertical 3D integration will play a vital role in enhancing performance and functional density while reducing the size and cost of next-generation RF systems. However, the shift to 3DHI also introduces a new set of challenges, ranging from novel processes and substrates to RFIC/MMIC design, packaging and thermal management. This workshop brings together leading experts from academia and industry to present the latest advances and design methodologies in heterogeneous integration and advanced packaging technologies for mm-wave and sub-THz applications. The talks span a wide range of critical topics, including interposer-based system integration, advanced simulation techniques, integration of III-V technologies, SiGe and CMOS platform optimization, and co-packaged system testing and calibration.
