For the radio frequency (RF)\/mm-wave systems in the 5G, it is critical to manage the loss and the impedance at the package level to achieve a superior system\u2019s electrical performance. Given the high loss and significant impedance mismatching of current wire\/ribbon-bonding technology, a low-loss and impedance-matched fused-silica stitch-chip technology is proposed and studied for polylithic integration of RF\/mm-wave systems in this dissertation. A summary of the work is as follows: (1) RF characterization and parasitics extraction are performed for interconnect components on the fused-silica stitch-chip, including coplanar waveguide (CPW) and compressible microinterconnect (CMI). (2) The impedance design of the assembled fused-silica stitch-chip is then investigated and experimentally validated. (3) Furthermore, such integration technology is demonstrated with commercial off-the-shelf (COTS) RF\/mm-wave dice (e.g., low noise amplifier) as a scalable chiplet-based module. (4) In addition, alternative off-chip I\/O technologies for the fused-silica stitch-chip (e.g., microbump and hybrid-bond) are studied and benchmarked in terms of parasitics for beyond-5G applications.\u003C\/p\u003E\r\n","format":"limited_html"}],"field_summary_sentence":[{"value":"Polylithic Integration using Fused-silica Stitch-chips For RF\/mm-Wave Systems: Simulation, Fabrication, and Characterization "}],"uid":"28475","created_gmt":"2023-07-05 12:54:14","changed_gmt":"2023-07-05 12:54:14","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2023-07-18T11:00:00-04:00","event_time_end":"2023-07-18T13:00:00-04:00","event_time_end_last":"2023-07-18T13:00:00-04:00","gmt_time_start":"2023-07-18 15:00:00","gmt_time_end":"2023-07-18 17:00:00","gmt_time_end_last":"2023-07-18 17:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Room 1116, Marcus Nanotechnology","extras":[],"related_links":[{"url":"https:\/\/teams.microsoft.com\/l\/meetup-join\/19%3ameeting_NzkwYmRjMWEtOTE5OC00ZDQwLWExN2UtNzEzOTcyNjE5OTE1%40thread.v2\/0?context=%7b%22Tid%22%3a%22482198bb-ae7b-4b25-8b7a-6d7f32faa083%22%2c%22Oid%22%3a%22c5a88b58-c4ae-4343-8d9b-7184047fb379%22%7d","title":"Zoom link"}],"groups":[{"id":"434381","name":"ECE Ph.D. Dissertation Defenses"}],"categories":[],"keywords":[{"id":"192484","name":"PhD Defense, graduate students"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
