  • Publication number: 20110159442
    Abstract: A semiconductor device is manufactured by a method including processes of trimming and molding resist patterns. A resist layer formed on a substrate is exposed and developed to form the resist patterns. The resist patterns are trimmed using a first gas plasma to change the profiles of the resist patterns. Widths of the trimmed resist patterns are increased using a second gas plasma to form processed resist patterns.

  • Patent number: 7564042
    Abstract: An ion beam apparatus includes a plasma chamber with a grid assembly installed at one end of the plasma chamber and a plasma sheath controller disposed between the plasma chamber and the grid assembly. The grid assembly includes first ion extraction apertures. The plasma sheath controller includes second ion extraction apertures smaller than the first ion extraction apertures. When the plasma sheath controller is used in this configuration, the surface of the plasma takes on a more planar configuration adjacent the controller so that ions, extracted from the plasma in a perpendicular direction to the plasma surface, pass cleanly through the apertures of the grid assembly rather than collide with the sidewalls of the grid assembly apertures. A semiconductor manufacturing apparatus and method for forming an ion beam are also provided.

  • Patent number: 7094702
    Abstract: A layer-by-layer etching apparatus and an etching method using a neutral beam which enables to control etching depth to an atomic level by controlling the etching of each atom of a material layer to be etched under precise control of the supply of an etching gas and irradiation of the neutral beam and enables to minimize etching damage. In the layer-by-layer etching method, a substrate to be etched, on which a layer to be etched is exposed, is loaded on a stage in a reaction chamber. An etching gas is supplied into the reaction chamber to adsorb the etching gas on the surface of an exposed portion of the layer to be etched. Excessive etching gas remaining after being adsorbed is removed. A neutral beam is irradiated on the layer to be etched on which the etching gas is adsorbed. Etch by-products generated by the irradiation of the neutral beam is removed.
