The SigmaDSC is based on continual innovation in marking solutions for new substrate materials, highest quality marks and factory automation, using laser technology to place permanent, highly readable marks on wafers to allow traceability of the wafers through each step in the semiconductor manufacturing process. The SigmaDSC system provides the compatibility, cleanliness levels, mark quality, and reliability required to support high-volume 100mm to 200mm production.

The key to the SigmaDSC’s uniform dot depth and roundness is TUI's precise pulse to pulse stability combined with sufficient power.
