Post-silicon semiconductors with nanomaterials
The semiconductor industry is approaching the physical limits of silicon while demand for computing power continues to grow. Nanomaterials such as carbon nanotubes promise faster and more energy-efficient transistors, but existing production methods cannot scale to industrial manufacturing. Chiral Nano develops equipment that integrates nanomaterials into chips with high precision. Its patented process grows high-quality nanomaterials, selects the best structures using automated microscopy and AI, and transfers them robotically onto wafers. This enables semiconductor manufacturers to build post-silicon chips for future technologies such as AI and quantum computing.
Chiral Nano is an ETH Zurich spin-off developing manufacturing equipment for the integration of nanomaterials into semiconductor chips. As demand for computing power is skyrocketing, the semiconductor industry faces increasing challenges as silicon-based technologies approach their physical limits. Nanomaterials such as carbon nanotubes offer a potential path forward, but existing production methods have not achieved the precision and scalability required for industrial manufacturing.
To address this challenge, Chiral Nano has developed a proprietary three-step integration process. The first step focuses on contamination-free growth of nanomaterials on a patented substrate. The materials are then characterized using automated microscopy and AI-based analysis to identify the highest-quality structures. In the final step, proprietary robotic equipment transfers the selected nanomaterials onto wafers with high precision, enabling the fabrication of nanomaterial-based transistors.
The company’s technology combines materials growth, automated inspection, and robotic transfer in a single manufacturing approach. According to the company, this process delivers significantly higher yields and speeds than existing nanomaterial integration methods and is designed to meet the requirements of semiconductor production.
Chiral Nano aims to help chip manufacturers move from research-scale applications to industrial production of nanomaterial-based devices. A key milestone is the transition from 100 mm research wafers to 300 mm wafers, the standard format used in large-scale semiconductor fabrication facilities.
The company was founded as an ETH Zurich spin-off and is building a team at the intersection of nanotechnology, semiconductor engineering, robotics, and automation. Its long-term vision is to become a leading supplier of equipment for post-silicon semiconductor manufacturing, enabling future generations of chips for applications such as artificial intelligence and quantum computing.
Founded in July 2023, Chiral Nano is led by CEO and Chairman Seoho Jung, whose career spans research and innovation in nanotechnology and advanced manufacturing. After positions at UC Berkeley and ABB Corporate Research, he completed his PhD at ETH Zurich, where he co-developed a high-speed production process for nanomaterial-based electronic devices and devised ultra-low-power carbon nanotube gas sensors. Jung is joined by co-founders Natanael Lanz (CTO/COO), who holds a PhD in motion engineering from ETH Zurich and previously worked at Trumpf and ETEL, and André Butzerin (CPO), who earned a PhD in mechanical engineering at ETH Zurich and previously worked at Siemens. The broader team brings expertise in project management, business development, nanoelectronics, and mechanical engineering through Jeroen Zandbergen, Jia Liu, Maria El Abbassi, and Marko Nikolic.
