Let's build together
Whether you’re a potential customer, investor, neighbour, researcher, or policymaker, we’re here to collaborate.
A launchpad for innovation
We partner with leading Dutch research institutions, including TNO and regional knowledge hubs, to co-develop next-generation manufacturing technologies, such as advanced wafer production. Our Farmsum facility will be more than a plant: it will be a launchpad for innovation in recycling, circular material flows, and integrated solar value chains.
RESiLICON aims to build an energy‑efficient polysilicon production line with a capacity of 26 kton (~13 GW) that transforms MG‑Si into ultra‑pure poly‑Si using the proven Siemens process. Our N11‑grade purity enables the production of ingots and wafers for the semiconductor industry, as well as high‑performance solar cells and panels—including advanced HJT and TOPCon technologies.
Strategic partnership with AMS: accelerating efficiency in polysilicon
RESiLICON has secured exclusive EMEA rights to Advanced Material Systems (AMS) technology—proven to cut energy consumption in polysilicon production by up to 30%. Already deployed successfully in South Korea and India, this breakthrough positions RESiLICON at the forefront of sustainable manufacturing in Europe. AMS is a global leader in polysilicon process innovation, with a strong legacy across the semiconductor and solar sectors. Together, we’re driving the shift toward cleaner, more efficient materials for the semiconductor and solar industries.
Frequently asked questions
-
Where will the plant be built?
RESiLICON has signed a reservation contract with Groningen Seaports (GSP) for a 22.5-hectare plot in Farmsum, Province of Groningen—an ideal location for polysilicon production. -
What is Polysilicon and why is it important?
Polysilicon is a high-purity form of silicon used as a key raw material in both the solar and electronics industries. It is widely recognized as one of the most critical materials driving the energy transition and powering the digital economy—including technologies like IoT and AI. The polysilicon produced by RESiLICON serves as feedstock for ingot manufacturers, who transform it into silicon ingots. These ingots are foundational to the semiconductor industry and essential for manufacturing solar cells and modules. -
What grades, what quality are you expecting to produce?
RESiLICON BV will produce ultra-pure sustainable polysilicon (9-11N) for the solar and the semiconductor industry. Apart from polysilicon RESiLICON will also consider producing specialty gases (Bi-chloro-silane and silane) for semiconductor and battery anodes manufacturing. -
Is this a new technology? Is it proven?
We will use Siemens' proven technology, in combination with our technology partner AMS, a globally recognised leader in polysilicon process technology. AMS has a strong track record in both the semiconductor and solar industries, having already demonstrated the technology in plants located in South Korea, the USA, Malaysia, and India. Their technology is expected to significantly reduce our energy consumption.
