Web1 day ago · In this study, shear rheological polishing was used to polish the Si surface of six-inch 4H-SiC wafers to improve polishing efficiency. The surface roughness of the Si surface was the main evaluation index, and the material removal rate was the secondary evaluation index. An experiment was designed using the Taguchi method to analyze the effects of … Web23 wafers per hour. Plus, we can even process thicker wafers; now we can dice 200-µm thick wafers, while our nanosec-ond laser process couldn’t go above 100 µm thickness.” Picosecond laser glass cutting: avoiding cracks and debris Another important picosecond pro-cessing application is glass cutting. This application is driven by the ...
