About us - Topsil

Topsil GlobalWafers A/S

Denmarks largest semiconductor company is located in the Copenhagen Cleantech Cluster area just outside the city of Frederikssund by Crown-Princess Mary’s bridge.

“Topsil is – and has always been – swimming among much larger fish in a big ocean and as such, the company has navigated its share of turbulence during a 60 year long history.

Yet Topsil has always managed to maintain a distinguished name with high quality products thanks to the dedicated and capable people working in the organization.

We anticipate that going forward, the rare degree of loyalty and combination of skills found in this unique company will flourish together with its new Global family.”

President of Topsil GlobalWafers A/S, Hans Peder Mikkelsen
