Postdevelopment Treatment Of Reusable Imaging Member To Remove Charges Patents (Class 430/125.1)
  • Patent number: 10203627
    Abstract: A method of depositing an unpackaged semiconductor die (“die”) onto a substrate. The method includes writing a latent image on a photosensitive drum. The latent image represents an outline for the die to be placed onto the substrate. The photosensitive drum is configured to have an electro-static charge and the die is transferred from the developing unit to the photosensitive drum so as to deposit the die onto the substrate according to the outline.

  • Patent number: 8828307
    Abstract: An imprint method includes contacting an imprint pattern of a mold and a resin material on a substrate. The resin material is cured by irradiating the resin material with light in a state in which the imprint pattern is in contact with the resin material. The mold is parted from the cured resin material, and gaseous molecules are irradiated, in an atmosphere in which the mold is placed, with an electromagnetic wave having a wavelength that is shorter than a wavelength of the light irradiating the resin material. The electromagnetic wave is emitted from an electrification removing light source that is provided in a lateral side of the mold. In the irradiating step, the gaseous molecules are ionized by the irradiation of the electromagnetic wave from the electrification removing light source. The ionized gaseous molecules are supplied into an atmosphere between the substrate and the mold to remove electrification of at least a portion of the mold.
