Improvement

Advanced technology leads to a higher yield rate in bevel polishing.

Get smart.

EBARA’s bevel polishing systems employ novel polishing techniques to process the bevel and backside of the wafers – an area that has attracted attention in recent years as a source of defects amid efforts to improve the yield rate of semiconductor production.

Bevel Polishing: Clean and reshape wafer

As the main source for wafer yield loss, our bevel polishing tools not only remove damages
to the wafer edge, but also clean and reshape the bevel.

For high volume production fully automated systems – EAC200bi-hv / EAC300bi-hv / EAC300bi-wb
