Laser Grooving Coating
Packing unit: 1 Gallon
Laser grooving fluid is a transparent and low-viscosity water-based coating fluid, suitable for coating on the surface of integrated circuit wafers to improve the yield of the laser grooving process. Laser grooving fluid is a water-based polymer solution containing polyvinyl alcohol or polyvinylpyrrolidone. It is spin-coated on the surface of the integrated circuit wafer to form a temperature-resistant polymer thin film. During laser grooving process, the fluid can improve production yield and eliminate quality problems such as cutting track cracking and dielectric layer peeling.
- Achieve cooling effect through vaporization of organic materials and improve laser grooving resolution.
- Rigid polymer film, prevents debris from splashing and scratching integrated circuits on wafer.
- Temporary coating, easily removed by rinsing with pure water.
