WCS-3F

TOPCover(TM) WCS-3F

Silicon/Sapphire Wafer protective coating solution for laser sawing(dicing, grooving, full cutting) during UV laser ablation.
Application : Si wafer,Poly-Si wafer, GaN-Si wafer, Low-k wafer, Metal layered wafer, very thin wafer, High luminent LED wafes, etc

Not removed melt Si particles during UV Laser sawing(Dicing, Grooving) can cause the unexpected problems.
These particles are hard to remove with only DI water cleaning.

To prevent this problems and to protect the chip surface, WCS-3F is needed to coat the surface of wafers before UV laser sawing(dicing, grooving, full cutting)
WCS-3F have excellent leveling, Good slippage after drying, Perfect cleaning with DI water..

WCS-3F is the next generaton goods for silicon/sapphire wafer protective coating solving problems of PVA basis one.
it is showing the perfect performance under high speed spin coating.
Especially 12-inch Si wafer, GaN-Si wafer, Metal layred wafer, and Hard-to-cut wafers with blade.

Characteristics.
