Canopus AI

What Canopus AI does

Canopus AI is a Grenoble-based software company founded in 2021 that builds AI-powered computational metrology software for semiconductor wafer and mask inspection. Its single core product, the "Metrospection" platform, applies deep learning to CD-SEM (Critical Dimension Scanning Electron Microscopy) and TEM (Transmission Electron Microscopy) images to deliver sub-nanometer process control, robust EPE-based measurements, early defect identification, and characterization of process variations and stochastics at advanced (angstrom-era) technology nodes. The platform also includes a synthetic SEM and TEM image generation engine that supports programmed-defect creation, D2DB data flow, and integration with CAD layout and TCAD 3D environments, alongside native support for vertex-to-pixel geometry handling, MULTIGON data, and curvilinear mask operations.

The company targets a narrow buyer base of semiconductor manufacturers and chip designers working on advanced nodes, where shrinking device geometries and tightening process windows make conventional metrology approaches insufficient. Its go-to-market was direct B2B enterprise sales to chip makers, with revenue generated through enterprise software licensing arrangements. Following Siemens' completed acquisition on January 12, 2026, Canopus AI now operates as part of Siemens' Calibre portfolio within the Xcelerator ecosystem, extending its distribution reach through Siemens' global EDA sales organization and enabling an end-to-end semiconductor manufacturing digital twin that links design intent to wafer-level outcomes.

No customer logos, pricing, funding details, or revenue figures are disclosed in the available data. Headcount is reported as 11–50 employees. The company's value proposition rests on domain-specialized AI applied to a precision-critical workflow at the leading edge of semiconductor manufacturing — a narrow but strategically important wedge that justified acquisition by a tier-1 industrial software strategic.

Core offering

Canopus AI develops and sells Metrospection, an AI-powered computational metrology software platform that bridges conventional wafer metrology and inspection for advanced semiconductor technology nodes. The platform delivers massive CD-SEM and TEM image processing, EPE-based measurements, defect identification, process variation characterization, and synthetic 2D/3D SEM image generation to support OPC/RET and angstrom-era process control for chip manufacturers.

Product overview

Canopus AI offers a single unified product platform called Metrospection, which provides comprehensive AI-driven wafer and mask metrology and inspection solutions for semiconductor manufacturing. The platform specializes in CD-SEM image metrology for high-throughput processing and TEM image metrology with synthetic image generation capabilities. All capabilities are delivered through one integrated software framework designed to address the extreme precision requirements of advanced technology nodes as device geometries shrink toward the angstrom era.
