Why dicinggrinding service by DISCO? DISCO HITEC EUROPE''s DicingGrinding Service (DGS) is an integral component of any manufacturing stage when it comes to high precision processing of ICs, MEMS, LEDs, other micro components and their inspection/metrology.
In the context of manufacturing integrated circuits, wafer dicing is the process by which die are separated from a wafer of semiconductor following the processing of the wafer. The dicing process can involve scribing and breaking, mechanical sawing (normally with a machine called a dicing saw) or laser methods are typically automated to ensure precision and accuracy.

Nanogrinding was performed based on a lapping process.[16] The abrasive grains were completely embedded in a soft metallic plate that was the grinding tool. Pumice was embedded in the grinding plate and remained there throughout the process. Between pumice particles, the basic soft metallicplate materials formed the plateaus.
