  • Method for manufacturing cured product pattern, method for manufacturing processed substrate, method for manufacturing circuit board, method for manufacturing electronic component, and method for manufacturing imprint mold
    Patent number: 11709430
    Abstract: A method for manufacturing a cured product pattern of a curable composition includes the steps of, in sequence, depositing a droplet of the curable composition onto a substrate; bringing a mold having an uneven pattern formed in a surface thereof into contact with the curable composition; curing the curable composition; and releasing a cured product of the curable composition from the mold. The mold has a recess having a bottom surface and a stair structure arranged to form an opening surface that becomes wider from the bottom surface toward the surface of the mold. In the contact step, the curable composition comes into contact with the stair portion after a top of the droplet comes into contact with the bottom surface.
