Webb28 feb. 2024 · As pad temperature increases with polish time, pad material with higher value of E'25/E'90 will tend to become relatively soft in comparison to the pad material having lower value of E'25/E'90. Increasing softness of the pad material will lead to higher dynamic shear force at pad-slurry-wafer interface which will increase the friction. WebbSilica-based slurries are widely used not only to polish SiO 2 but also other materials, for example (poly)silicon and copper. As listed and characterized in Section 15.2, the three main types of SiO 2 abrasive formulations commonly used are: Stöber- and alkali-silicate sol and fumed-silica dispersions [8–10,21].
