Slurry wafer
WebbCMP involves polishing the metallic surface of the wafer with a pad while adding slurry. Polishingslurry is one of the most costly consumablesin the CMP process. For this reason, the recycling of CMP slurries has become a new challenge for the microelectronic industry and has been investigated for the past 12 years [1–4]. Webb27 okt. 2024 · Wafers, whose dimensions are gradually increasing and can reach 200 mm (8 inches), are made of very pure material which, during the manufacturing process, must be polished to obtain a very even and smooth surface. This result can be achieved by applying lapping, polishing, and grinding techniques.
