Abstract
Material properties and directed self-assembly of a block copolymer containing hybrid material are presented in this paper. The hybrid material, which is a mixture of poly(styrene-b-ethylene oxide) (PS-b-PEO) and organosilicate (OS), shows morphologies of microdomains similar to those of organic diblock copolymers depending on the fraction of each phase, i.e. PS and PEO+OS. This material system shows very strong segregation between phases, which provides well defined microdomains in thin films even right after spin coating. The strong segregation also makes it possible to generate microdomains of sub-10 nm length scale regime. The hybrid is found to be directed self-assembly (DSA)- friendly, thus typical topographic and/or chemical guiding patterns can be used for DSA of the hybrid.
