Topsil GlobalWafers A/S

EUDP

Topsil GlobalWafers A/S is one of just five companies in the world with the advanced capability to manufacture ultra-pure 200 mm silicon wafers used in power electronics. Now, the company is advancing even further, building on its unique position in the industry.

The project

With support from the Danish Energy Technology Development and Demonstration Program (EUDP), Topsil is launching the FZ300 project to develop the world’s first ultra-pure 300 mm Float Zone (FZ) silicon wafers – a big step in future-proofing Europe’s energy technology supply chain.

The transition from 200 mm to 300 mm wafer diameter will allow to increase production efficiency and reduce emissions, making power semiconductors more cost-effective and sustainable. These components are vital enablers of the green transition.

The project will develop and demonstrate a new R&D crystal growth machine capable of producing ultra-pure 300 mm FZ silicon crystals – something that was never before achieved. The work builds on six decades of engineering experience at Topsil, combined with advanced process simulations conducted by the Technical University of Denmark (DTU).

1st Mile’s work with Topsil

In 2024, we at 1st Mile supported Topsil in crafting their successful EUDP application. The result was a grant of DKK 44.2 million for the FZ300 project, running from 2025 to 2028 and including DTU as a partner.

This breakthrough project is expected to secure Danish and European leadership in strategic semiconductor production for the energy sector.
