Siemens has acquired Canopus AI, a specialist in computational and AI-driven metrology solutions, to enhance precision and efficiency in semiconductor wafer and mask inspection processes. The acquisition strengthens Siemens’ position in the semiconductor manufacturing ecosystem and expands its end-to-end semiconductor design and manufacturing digital thread by integrating advanced AI-enabled metrology technologies.

As semiconductor device geometries continue to shrink and production volumes increase, manufacturers face growing challenges in maintaining yield and quality. Massive metrology has become essential to address these demands. Canopus AI’s AI-powered inspection and measurement solutions complement Siemens’ existing portfolio, enabling semiconductor manufacturers to achieve higher accuracy, improved process control, and greater operational efficiency.

“The acquisition of Canopus AI exemplifies Siemens' commitment to leveraging industrial AI to solve critical challenges in semiconductor manufacturing,” said Tony Hemmelgarn, president and CEO, Siemens Digital Industry Software. “By combining the computational lithography and manufacturing physics simulation capability in our Calibre portfolio with Canopus-AI’s advanced metrology and inspection technologies, we are creating a differentiated, end-to-end EDA digital thread that improves the fidelity of printed wafer patterns, accelerates yield ramp, and reduces time-to-volume for advanced nodes. This integration further advances our vision of a comprehensive, high-accuracy semiconductor manufacturing digital twin, enabling sub-nanometer process control and mask development.”

Founded in 2021 and based in Grenoble, France, Canopus AI develops software solutions for wafer and mask metrology and inspection. The company is pioneering an approach known as “Metrospection,” which integrates AI into metrology and inspection workflows to bridge gaps between traditional measurement and inspection techniques. This approach is designed to help semiconductor designers and manufacturers meet the extreme precision requirements of advanced technology nodes.

“We are delighted to join Siemens and bring the power of AI-enabled metrology in the semiconductor industry to a broader audience as part of Siemens’ EDA community of users,” said Joël Alanis, chief executive officer of Canopus AI. “Together, we’ll empower innovators pushing the boundaries of semiconductor design and manufacturing with robust wafer and mask metrology and inspection and help them to meet the challenges of the rapidly changing semiconductor industry.”
