1. A microimprint/nanoimpnnt uniform pressing apparatus for providing uniform imprinting pressure to a molding material layer formed between a substrate and a mold, the microimprint/nanoimprint uniform pressing apparatus comprising:
a holding unit formed with an opening at one end thereof and an accommodating space therein;
a driving unit connected to the holding unit;
a uniform pressing unit being directly in contact with the substrate or the mold and comprising a fluid and a bag-shaped flexible membrane;
a carrier unit for providing support for performing imprint molding; and
two transmission units provided at two sides of the carrier unit respectively, for transmitting the substrate in the form of a continuous strip,
wherein the fluid fills in the accommodating space and the opening is sealed by the flexible membrane such that the fluid is enclosed by the holding unit and the flexible membrane.
