In this talk, Dr. Xuejun Xie shares his personal journey—from academic research in 2D transition metal dichalcogenides (TMDs), to deep involvement in semiconductor R&D across the U.S. and Asia, to founding PhantaField, a company dedicated to low-temperature PP-MOCVD growth and 3D monolithic integration of atomically thin semiconductors for next-generation computing.
The talk covers the scientific motivations, technological inflection points, and market forces that led to the creation of PhantaField. It introduces the company’s proprietary PP-MOCVD platform, its monolithic 3D embedded memory IP targeting 150–3000 TB/s-class bandwidth, and the long-term roadmap of enabling compact XR systems and future digital-twin intelligence.
Attendees will gain insight into how atomic-scale materials research translates into real-world hardware, how startups can position themselves at the intersection of AI and semiconductors, and why 2D materials are critical for the post-HBM era. The talk concludes with a discussion of how synchronized AI, digital twins, Noninvasive cell resolution Brain Computer Interface (BCI), and next-generation hardware converge to shape the future of human-machine symbiosis.
Dr. Xuejun Xie
Dr. Xuejun Xie is the founder of PhantaField, a semiconductor company pioneering low-temperature PP-MOCVD growth of 2D TMD materials and monolithic 3D embedded memory for AI computing. He received his PhD from the University of California, Santa Barbara, where he focused on advanced materials and device physics. His career spans research in 2D semiconductors, semiconductor manufacturing technology, and high-bandwidth memory architecture.
At PhantaField, he leads the development of atomically thin transistor technology and 3D memory IP designed to break AI’s memory bandwidth bottleneck. His work extends further into XR systems, digital twins, BCI, and long-term visions for synchronized AI and human–machine co-evolution.
