A method of forming a CMP pad includes providing a solution of a block copolymer (BCP), where the BCP includes a first segment and a second segment connected to the first segment, the second segment being different from the first segment in composition. The method further includes processing the BCP to form a polymer network having a first phase and a second phase embedded in the first phase, where the first phase includes the first segment and the second phase includes the second segment, and subsequently removing the second phase from the polymer network, thereby forming a polymer film that includes a network of pores embedded in the first phase. Thereafter, the method proceeds to combining the CMP top pad and a CMP sub-pad to form a CMP pad, where the CMP top pad is configured to engage with a workpiece during a CMP process.
