proteanTecs Certified for 2nm Chip Monitoring in TSMC’s N2P Process

27 September, 2025

Haifa-based startup introduces embedded agents and thermal sensors in nanosheet chips, enabling continuous monitoring and analytics for AI, cloud, automotive, and next-gen high-performance system

Following the production of a test device for a TSMC customer, Haifa-based proteanTecs announced that its on-chip monitoring technology has been validated for TSMC’s most advanced node to date, the 2-nanometer N2P process. The company’s monitoring system embeds sensors and “agents” inside chips during design, then continuously transmits performance data throughout the product lifecycle.

The proteanTecs Hardware Monitoring System was integrated into a high-performance computing chip designed for a TSMC customer. Test wafers were fabricated and evaluated using industry-standard tools, with results compared against proteanTecs’ system data. The evaluation confirmed the monitoring system met all defined expectations and is ready for mass production in 2nm devices. According to co-founder and CTO Evelyn Landman, the certification underscores the company’s leadership in chip monitoring and analytics.

“Our close collaboration with TSMC enables us to support joint customers more effectively,” Landman said. “By combining our hardware with software applications, we provide insights from design through field operation—delivering continuous performance monitoring, dynamic fault management, and data-driven guidance for future development.”

Breakthrough in On-Chip Temperature Sensing

A key milestone in the certification was solving the challenge of temperature measurement in 2nm chips. Traditional methods rely on thermal diodes based on bipolar junction transistors (BJTs), but their voltage requirements make them unsuitable below 3nm. proteanTecs developed Local Voltage and Thermal Sensors (LVTS) that use existing transistors in the chip, achieving ±1.0°C accuracy and compatibility with current and next-generation GAA transistor architectures.

The testing was carried out under TSMC’s IP Alliance Program, part of its Open Innovation Platform (OIP). proteanTecs’ full platform—spanning embedded agents, sensors, and connectivity infrastructure—has been optimized for nanosheet transistor designs and is now fully certified and available to TSMC customers. The technology is especially relevant for high-performance markets including AI, cloud computing, mobile, automotive, and communications.

Founded in 2017 by veterans of Mellanox, proteanTecs has raised about $250 million to date. Its backers include Avigdor Willenz, Intel Capital, Walden, Viola, and others. Just two weeks ago, the company closed a $51 million Series D round led by IAG Capital Partners, with participation from Arm and Siemens alongside existing investors such as Intel, MediaTek, Koch, Porsche, and Willenz.
