Atomera Inc. develops and commercializes MST, a patented semiconductor materials technology designed to improve transistor performance and manufacturing yield. The company’s core idea is to insert a thin engineered layer into the wafer stack to address crystal lattice mismatch and other device-level limitations, including in compound semiconductors such as GaN. Atomera has historically focused on licensing, engineering services, and customer evaluation work rather than high-volume chip manufacturing. It is headquartered in the United States, listed on Nasdaq Capital Market under ATOM, and remains in an early commercialization phase with limited revenue to date.
