Topsil GlobalWafers

Fully Automatic ID Saw Machine

ProInvent has many years of experience as a supplier of fully automatic, recipe-controlled saw machines for distribution of, for example, silicon crystals, metal and ceramic monoliths.

Topsil GlobalWafers A/S wanted a fully automatic ID saw. Specifically, they needed an automatic saw that cuts with a diamond-coated inner diameter of a foil-thin saw blade. This equipment is used for the production of silicon ingots of given lengths of long silicon rods, made of single crystals. It was a requirement that the saw could cut a very thin test wafer for each ingot.

ProInvent developed and delivered a fully automated solution for Topsil GlobalWafers. A basic saw was delivered from Meyer Burger GmbH. All necessary automatic handling equipment, servo equipment, PLC and HMI with recipe-control were specially designed, built and commissioned by ProInvent over 8 months. The new saw has high productivity, minimum material loss due to a very thin saw track, reduced number of chips and cracks, and better surface quality in the cutting face.
