Abstract:
1. A method of producing a 3-D mold that is configured to control depth within 10 nm and form a line width of 200 nm or less, the method comprising: an irradiation step of irradiating an electron beam to a resist layer of an object of processing that has the resist layer constituted with a polysiloxane-based material on or above a substrate; and a developing step of developing the resist layer after the electron beam is irradiated to form an uneven part at the resist layer, the method further comprising producing a 3-D mold having a plurality of uneven parts of different processed depth by forming the processed depth proportional to the size of each acceleration voltage or each dosage in a plurality of irradiations in a series of steps of successively performing the plurality of irradiations by fixing one of the acceleration voltage and the dosage of an electron beam and changing the other, and then developing, wherein the irradiation step includes a step having irradiation conditions such that the acceleration voltage is from 1 kV to 3kV without generation of the backscattering and the dosage is 400 μC/cm
