Silicon – the most important raw material for us
As wafers consist almost entirely of hyperpure silicon, silicon is by far the most important raw material for Siltronic. After oxygen, silicon is the second-most frequently found element in the Earth’s crust and is non-toxic. For this reason, we regard silicon wafers as an unrivaled raw material for manufacturing semiconductors and the raw material of choice for our products in the long term.
Auxiliary materials
In addition to the raw material silicon, auxiliary materials such as chemicals, gases and polishing agents also play a role in our production process.
We are working on improving the production steps with the aim of reducing the specific consumption of auxiliary materials. The reduction is usually achieved through recycling, e.g. reductions in polishing agents and cleaning baths.
