  • Publication number: 20060286193
    Abstract: In an imprint device and a microstructure transfer method, a fluid is ejected at the back of at least either a stamper or a transfer target body during pressurization of the stamper and the transfer target body. The fluid is ejected through plural holes formed in a stage disposed at the back of at least either the stamper or the transfer target body. The plural holes are connected to independent pressure regulating mechanisms, which can individually control the amount of fluid ejection, the timing of start of ejection, and so on. When the stamper is peeled from the transfer target body, the plural holes are evacuated to fix the stamper or the transfer target body to the stage by suction so as to peel the stamper.
