Cmp wafer meaning
WebNov 1, 2005 · Material removal in CMP occurs during intervals of pad-wafer contact separated by intervals of non-contact. One predictable sequence of non-contact intervals for a fixed point on the wafer is the traverse of the pad grooves, during which the wafer surface is renewed with fresh chemistry and heat is conveyed away. It is well understood that … WebJul 30, 2024 · As another way to engineer the bonded wafer edge in advance, the wafer edge can be lowered in a defined way before the direct bonding, by a masking and silicon etching processes, to produce a very clean, well-bonded wafer edge after grinding and polishing of the membrane wafer. 7 For the etching process, wet chemical etching, such …
