Silicium necessitates a particular process in order to be formed into the desired components. DRIE, or Deep Reactive Ion Etching, has, in only just 10 years, conquered its own place in watchmaking. The space in which this process takes place is extremely important in determining the final result. Silicium is made in a cleanroom, just like microprocessors. In order to enter the space where Sigatec has its main operations, everyone needs to wear specific equipment that protects the workshops. In a pressurised air chamber, each particle suspended in the air, on your skin, clothes, hair or beard is vacuumed or enclosed behind a barrier made of synthetic and antistatic fabric.
