Atomera's quantum-engineered MST® films and Synopsys' TCAD simulation combine to accelerate next-generation GaN device development for RF and power electronics

Atomera Incorporated (NASDAQ:ATOM), a semiconductor materials and technology licensing company, today announced an expanded collaboration with Synopsys, Inc. — the leader in engineering solutions from silicon to systems — to advance gallium nitride (GaN) device modeling for radio frequency (RF) and power semiconductor applications. The work builds on the companies' long-standing relationship around Synopsys' Sentaurus™ TCAD and Atomera's MSTcad™ toolset and extends the collaboration into GaN workflows to support bringing higher-quality GaN solutions to market.

"Synopsys has a strong history of working with innovative semiconductor technology companies to help customers evaluate and integrate new capabilities," said Rahul Deokar, executive director of product management for Manufacturing Solutions at Synopsys. "Our broadened collaboration with Atomera is focused on advancing GaN TCAD simulations to gain deeper insights into how advanced materials can be leveraged to design more efficient devices and address the semiconductor industry's future RF and power challenges."

Under the collaboration, Atomera will use Synopsys' Sentaurus TCAD tools to develop a GaN calibration methodology for TCAD workflows, create marketing materials and calibrated TCAD decks for GaN devices, and provide product feedback to Synopsys.

Synopsys and Atomera have worked together for years to enable modeling of Atomera's MST technology within Synopsys' Sentaurus TCAD environment. This collaboration enables support for Atomera's MSTcad capabilities and allows customers and partners to evaluate the physical and electrical effects of MST using Synopsys' process and device simulation tools.

"This collaboration represents a natural next step in our long-standing collaboration with Synopsys," said Scott Bibaud, president and CEO of Atomera. "We have already shown the value of combining MST with Synopsys' Sentaurus tools through MSTcad, and we are excited to extend that relationship into GaN to continue broadening Atomera's reach into high-value RF and power semiconductor markets."
