Media Alert: Atomera Highlights MST® as a Toolbox for Engineering Silicon Virtual Substrates at 2025 CINT Annual User Meeting

Audio By Carbonatix

--(BUSINESS WIRE)--Sep 11, 2025--

Atomera Incorporated (Nasdaq: ATOM):

Marek Hytha, Atomera Chief Scientist, will present research on Mears Silicon Technology™ (MST®) — technology that enhances the performance of silicon-based semiconductor devices by inserting ultra-thin layers of oxygen into silicon wafers — as an atomic-scale substrate engineering platform enabling new frontiers in beyond-CMOS applications.

With adjustable layer count, spacing and composition, MST can be precisely engineered to enhance key semiconductor properties, including diffusion blocking, variability, mobility, gate leakage and reliability across GaN-on-Si, piezoelectric and spintronic applications. The poster will cover:

• MST Substrate for GaN-on-Si Epitaxy
  • Building on its successful use in CMOS and RF-SOI devices, MST grown on Si (111) substrates is now being explored as a virtual substrate for GaN-on-Si Epitaxy to improve material quality and device performance, reduce leakage current and provide higher breakdown voltage for RF and power applications.
• MST Piezoelectric Substrate
  • The oxygen atoms in MST form polar Si–O–Si dipoles. These dipoles, while randomly oriented in their as-grown state, can be aligned through applied electric fields and mechanical stress. This alignment induces net polarization, effectively generating a measurable piezoelectric effect in an otherwise non-piezoelectric silicon, opening pathways for integrating piezoelectric functions directly into standard silicon chips.
• MST-Mn Diluted Magnetic Semiconductor Virtual Substrate for Spintronics
  • MST enables spintronic applications by supporting stable, room-temperature diluted magnetic semiconductors (DMS) in silicon. With uniform distribution of elements like manganese (Mn), MST is expected to provide efficient spin injection and carrier-mediated ferromagnetism, unlocking next-gen devices like MRAM and spin-LEDs for energy-efficient computing.
