There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Title: Heterogeneous Integration for High-Speed mm-wave Communications

Abstract: The objective of the proposed research is to demonstrate heterogeneous integration for 6G applications that include back-end high-speed processing. AI applications require specialized chips that need to communicate with each other through interconnections. The primary focus of this work is to demonstrate high-speed communication between chips through non-TSV based integration. The proposed research demonstrates highly integrated modules with embedded dies and thin film components such as antennas working at high frequencies. An integrated and miniaturized printed quasi-Yagi antenna and antenna arrays have been designed and fabricated on glass interposer as part of the proposed research. A probe-station-based measurement set-up has been created to characterize the return loss, the antenna gain and the radiation pattern. Via chain structures have been designed and fabricated to characterize the chip-to-package microvia interconnect loss in low-loss polymer buildup film in D-band (110 - 170 GHz) with 2x lower loss compared to flip-chip transitions.
