Synopsys (SNPS) Stock: GaN Device Modeling Deal Extends Atomera Collaboration

Key Takeaways

• Semiconductor design software provider Synopsys (SNPS) and materials innovator Atomera (ATOM) are broadening their TCAD partnership to encompass gallium nitride (GaN) device modeling capabilities.
• The expanded collaboration centers on RF and power semiconductor use cases leveraging Synopsys’ Sentaurus TCAD platform.
• Under the arrangement, Atomera will develop GaN calibration processes and deliver calibrated TCAD decks using Sentaurus TCAD tools.
• The agreement builds upon previous collaboration that integrated Atomera’s MST technology into the Sentaurus simulation environment.
• Atomera shares have surged 187% year-to-date to $6.19, while SNPS stock showed no material reaction to the announcement.

The partnership between Synopsys and semiconductor materials innovator Atomera has entered a new phase, with both companies announcing Thursday an extension of their collaboration into the gallium nitride device modeling arena.

Synopsys, Inc., SNPS

The companies’ initial collaboration centered on integrating Atomera’s Mears Silicon Technology (MST) into Synopsys’ Sentaurus TCAD simulation platform. Through Atomera’s MSTcad toolkit, this integration enabled industry partners and customers to simulate and assess both the physical characteristics and electrical behavior of MST technology using Synopsys’ industry-standard simulation infrastructure.

This latest development leverages that established framework and redirects it toward GaN modeling workflows — a distinct material system critical to RF communications and power electronics applications.

According to Rahul Deokar, who serves as executive director of product management for Manufacturing Solutions at Synopsys, the enhanced collaboration aims to utilize GaN TCAD simulations for understanding how next-generation materials can drive superior device efficiency.

The partnership terms call for Atomera to deploy Sentaurus TCAD tools in developing a comprehensive GaN calibration framework for TCAD processes. Additionally, Atomera will produce marketing collateral and validated TCAD decks specifically for GaN devices, while delivering continuous product insights back to Synopsys.

Sentaurus TCAD Forms the Foundation

At the heart of this expanded partnership sits Synopsys’ Sentaurus TCAD, a comprehensive platform of process and device simulation capabilities widely deployed throughout the semiconductor sector for transistor-level modeling of material properties and structural characteristics.

The Atomera collaboration enables Sentaurus to accommodate MST-based device simulations — and with this extension, GaN-based modeling as well. This expansion increases the variety of device architectures that Synopsys’ simulation tools can accurately model and calibrate.

Atomera’s Market Position

Atomera operates as a semiconductor materials and intellectual property licensing firm. The company’s MST technology represents a quantum-engineered thin-film solution engineered to enhance transistor performance metrics and energy efficiency.

Shares of ATOM have climbed 187% since the beginning of the year, trading at $6.19 when the partnership expansion was disclosed, translating to approximately $237 million in market capitalization. The stock declined 2.37% during the trading session.

InvestingPro data suggests ATOM may be trading above its Fair Value assessment. Analysts don’t anticipate the company achieving profitability in the current fiscal year, although its balance sheet shows a cash position exceeding debt obligations.

The company’s fourth quarter 2025 financial results revealed an EPS of -$0.14, matching analyst projections, while revenue of $50,000 fell short of the $100,000 consensus estimate by half.

In February, Atomera secured approximately $25 million in capital via a direct placement of 5 million common stock units priced at $5.00 per unit to institutional buyers.

The company also recently appointed Nishant Sinha to the position of VP of marketing, tasked with accelerating MST technology penetration throughout the semiconductor ecosystem.
