Innovation Through Passion

From ETH Zürich to a growing startup


Our Story


Our Beginnings

Dr. Ali Altun discovered the principle effect behind the UNISERS technology during his research work at ETH Zurich.

Due to his many years of work experience in the semiconductor industry in Korea, Ali realized that his discovery could actually solve one of the key issues in chip production.



Together, Dr Ali Altun and mechanical engineer, Timo Schneider, incorporated UNISERS AG in 2019.

With very little funding, they managed to build the first prototypes and demonstrated the unique capabilities of the technology on 300mm wafers to various industry customers.


Seed Investment

On 16 February 2023, UNISERS announced the closing of a USD 14 Million seed investment round with Intel Capital, M Ventures, Swisscom Ventures and RSBG Ventures.

Surface-enhanced Raman scattering (SERS) has been around since the days of acid wash jeans and mix tapes, but it has certainly never been as widely commercialized. UNISERS CEO and Co-founder Ali Altun was curious to find out why.

He noticed a common thread: the majority of efforts of the research community focused on increasing sensitivity of SERS. Ali realized that the missing link wasn’t the sensitivity of the technique, but its lack of universality.

Without a reliable way to apply the technology to a wide range of contaminants, it can’t truly make an impact.


Timo Schneider, Chief Engineer and Co-founder of UNISERS, is building the application of the novel UNISERS technology. His affinity for rapid prototyping and innovative, yet practical, hands-on approach enabled UNISERS to accelerate learnings from the parameters of the early tool and quickly adapt.

Soon, UNISERS was able to process 300 mm (12 in) wafers on our self-built prototype, finding and identifying contaminations that are otherwise invisible to the existing state-of-the-art technologies in the industry.


Our vision is to revolutionize contamination control
