  • Patent number: 11948795
    Abstract: Provided are a method for manufacturing a single-crystal semiconductor layer. The method of manufacturing the single crystalline semiconductor layer includes performing a unit cycle multiple times, wherein the unit cycle includes a metal precursor pressurized dosing operation in which a metal precursor is adsorbed on a surface of a single crystalline substrate by supplying the metal precursor onto the single crystalline substrate while an outlet of a chamber in which the single crystalline substrate is loaded is closed such that a reaction pressure in the chamber is increased; a metal precursor purge operation; a reactive gas supplying operation in which a reactive gas is supplied into the chamber to cause a reaction of the reactive gas with the metal precursor adsorbed on the single crystalline substrate after the metal precursor purge operation; and a reactive gas purge operation.

  • Patent number: 11940734
    Abstract: The inventive concept provides a substrate treating apparatus. The substrate treating apparatus includes a chamber having a treating space therein; a supply line having a first open/close valve installed thereon and configured to supply a treating fluid to the treating space; a heater installed on the supply line and configured to heat the treating fluid; an exhaust line having a second open/close valve installed thereon and configured to exhaust the treating space; and, a controller configured to control the first open/close value and the second open/close valve such that the treating fluid heated is supplied to and exhausted from the treating space before a treating process is performed on a substrate in the treating space.

  • Patent number: 7585596
    Abstract: Methods and systems of creating a photo-mask to form continuous relief micro-structures in photo-active material. This technology uses a basic amplitude mask or electron-beam to create a binary phase grating with pi-phase depth on a transparent reticle coated with photo-active material. The reticle is then used as a phase mask for the fabrication of analog micro-elements. The mask is used in an image reduction machine such as an optical stepper. The period and duty cycle of the phase gratings can be varied to create the proper analog intensity for the desired micro-profile on the photo-active material. The design, analysis, and fabrication procedure of this invention for prisms and positive micro-lenses has been demonstrated.
