  • Patent number: 8919840
    Abstract: An apparatus for the micromanipulation of micro-sized objects includes a micromanipulation device in the form of a hollow frame having a base, resiliently deflectable arms projecting from the base and defining a gap for receiving a micro-sized object, and a saddle connected to the tips of the arms between the base and the tips. A force generating device applies a force to the saddle to deflect the tips inwards to close the gap about the micro-sized object. A fixture is provided for supporting the micromanipulation device and force generating device. The force generating device can be a micrometer. The micromanipulation device is configured for production using micro-fabrication techniques. The micromanipulation device may include a piercing element for piercing an object positioned between the arms of the device, and may further include a notch aligned with the piercing element for retaining the object.

  • Patent number: 8052413
    Abstract: An improved imprint device is disclosed. It comprises a drive component, an imprinting object, and at least one mold, stacked together within a chamber, a fluid supplier is used for providing the solvent fluid into the chamber through a pipe. The solvent fluid will permeate the imprinting object, and the imprinting object will be plasticized at the temperature lower than the glass transition temperature. The drive component is used for driving the mold to the plasticized imprinting object, so that the pattern on the mold will be imprinted on the imprinting object. It is the advantage of the present invention to reduce the process temperature, prevent the pattern distortion, and save the process time. Furthermore, by using the fluid and a barrier film as a pressing medium, the pressure can be applied to the object and the mold uniformly, such that a large area imprint can be achieved.
