Patent ID: 7014534

Claim:
A method for manufacturing a substrate comprising the step of polishing a substrate to be polished with a polishing composition comprising an abrasive and water with a polishing pad of which surface member has an average pore size of from 1 to 35 μm, wherein the abrasive comprises particles having particle sizes of from 5 to 120 nm in an amount of 50% by volume or more of the entire amount of the abrasive, wherein the abrasive comprises: (i) 10 to 100% by volume of small size particles having particle sizes of from 5 nm or more and less than 40 nm based on an entire amount of the abrasive particles having particle sizes of from 5 to 120 nm; (ii) 0 to 70% by volume of intermediate size particles having particle sizes of from 40 nm or more and less than 80 nm based on an entire amount of the abrasive particles having particle sizes of from 5 to 120 nm; and (iii) 0 to 40% by volume of large size particles having particle sizes of from 80 to 120 nm based on an entire amount of the abrasive particles having particle sizes of from 5 to 120 nm.
