摘要： A method of patterning magnetic material includes forming a ferromagnetic material layer containing one element selected from the group consisting of Fe, Co and Ni on a substrate, selectively masking a surface of the ferromagnetic material layer, and making nonferromagnetic. The making nonferromagnetic step includes exposing an exposed portion in halogen-containing reaction gas, changing magnetism of the exposed portion and a lower layer thereof by chemical reaction, and making the exposed portion a nonferromagnetic material region. A magnetic recording medium is fabricated by using the magnetic material patterning method and includes a plurality of recording regions made of ferromagnetic materials, each containing at least one element selected from the group consisting of Fe, Co and Ni, and a nonferromagnetic material region for separating the recording regions from each other. The nonferromagnetic material region is a compound region of the ferromagnetic material and halogen.

摘要： The present invention provides a pattern forming method using phase separation structure of self-assembling block copolymer and minimizing variations in pattern. A substrate having groove structure pre-formed thereon, is coated with a solution of the block copolymer comprising at least one block having a mesogen group. The block copolymer is caused to self-assemble in the groove to form block copolymer assemblies, which are regularly arrayed. The invention also relates to a processing method of processing a substrate by the use of the pattern obtained by the pattern forming method as a template.
