    摘要: A nanoimprint system and methods for separating imprinted substrates with nano-scale patterns from mold for manufacturing. Generally, the system includes means to create, monitor, and control relative movement between the mold and substrate for separation. It is capable of controlling where and when the separation happens and finishes. The relative movement may be generated by motion stages, springs, stage driven flexures, inflatable O-rings, gas flow, and other mechanical means. It may be monitored by separation force, overhead camera, and vacuum/pressures in different area of the system. The relative movement may be any combination of stages movements and movement sequences. The separation speed, direction, and force can be well controlled in the system to achieve fast and reliable separation between mold and substrate, and at the same time maintain the pattern shape and details on the consolidated imprint resist.

    摘要: A process of compression molding an article from a curable resin is provided that includes opening a mold to an open position by displacing an upper die having an upper mold surface from a lower die having a lower mold surface. Resin is placed a mold surface and the dies are closed to an intermediate start position at a rate of from 1 to 10 cm/sec. The dies are then closed to a start position at a rate of between 25 and 60% of the rate of closure to the intermediate position. A shroud volume is evacuated for at least 3 seconds to a reduced pressure of less than 0.16 atmospheres while continuing to press toward a mold cavity volume at a rate of between 12 and 30% of the rate of closure to the intermediate start. The reduced pressure is removed as the full compression is applied.
