SANTA CLARA, Calif., April 29, 2025 - Silvaco Group, Inc. (Nasdaq: SVCO) (“Silvaco” or the “Company”), a provider of TCAD, EDA software and SIP solutions that enable semiconductor design and digital twin modeling through AI software and innovation, today announced the strategic acquisition of Tech-X Corporation, a leading provider of multi-physics simulation software used in applications such as Photonics, Electromagnetics and Plasma Dynamics.

Tech-X cutting-edge tools enable:

•Multi-physics simulation of electromagnetic, and electrostatics in complex dielectric and metallic environments;

•Combination of computational speed leveraging GPUs, and high-fidelity results for Photonics applications;

•Plasma Dynamics simulation trusted by engineers and researchers in aerospace and semiconductor manufacturing; and

•Monte Carlo simulation solution used for radiation analysis in aerospace applications.

By combining Tech-X’s unique multi-physics simulation tools with Silvaco’s Victory TCAD platform, customers will be able to create more accurate digital twin models for photonics, semiconductor devices and wafer-scale plasma etching —accelerating innovation across the industry. Tech-X brings deep expertise to Silvaco in developing state-of-the-art algorithms that harness high-performance, multi-node GPU-based computing to significantly improve simulation speed and accuracy.

“Bringing Tech-X’s expertise and multi-physics simulation technology into Silvaco represents a significant step forward in our growth strategy for expansion into AI applications with technologies, talent and new customers,” said Babak Taheri, CEO of Silvaco. “By leveraging our TCAD foundation, we are expanding further into fast multi-physics transistor-level simulation from device to wafer-scale geometries, for photonic components, processes, materials, and plasma modeling. We’re also thrilled to welcome Professor John Cary to the team. His 40+ years of experience in computational physics will play a key role in accelerating our innovation and expanding our presence in the rapidly growing photonics market.”

“We are excited to join forces with Silvaco and take advantage of the many synergistic capabilities between our organizations,” said John Cary, CTO of Tech-X and Professor of Physics at the University of Colorado, Boulder. “By leveraging Silvaco’s global reach and strong technical team, we see tremendous opportunities to expand the application of Tech-X’s advanced photonics and plasma modeling technologies across the semiconductor and photonics industries.”
