Then validate the shortlist with controlled trials on your own process.<\/div><\/details><details><summary>Should I choose a slurry on price?<\/summary><div class=\"ans\">No. Litre price is one of the least useful comparison numbers. Consumption rate, achievable throughput, dilution and especially yield impact usually dominate the real cost, so total cost of ownership is the correct basis for selection.<\/div><\/details><details><summary>Can I reuse a slurry that worked at another fab?<\/summary><div class=\"ans\">Not reliably. CMP is integration-specific \u2014 films, feature sizes, pads, cleans and tools differ between fabs and even between steps, so a slurry must be re-validated on your own structure rather than assumed to transfer.<\/div><\/details><details><summary>What is the most important selection criterion?<\/summary><div class=\"ans\">There is no single one \u2014 the material and stop layer set the chemistry, then removal rate, uniformity, selectivity and defectivity must all be balanced against your specific target. The right slurry has the widest, most robust window that meets every requirement at once.<\/div><\/details><details><summary>Why does pad and clean compatibility matter in selection?<\/summary><div class=\"ans\">The slurry is one part of a consumable system. It must work with the pad and conditioner and leave residues that the post-CMP clean can remove. A slurry that polishes well but defeats the clean or wears the pad poorly is not a viable production choice.<\/div><\/details><details><summary>Can a datasheet alone qualify a slurry?<\/summary><div class=\"ans\">No. Datasheet figures are obtained under reference conditions.
