  • Publication number: 20100233622
    Abstract: Disclosed is a method for manufacturing fine patterns of semiconductor devices using a double exposure patterning process for manufacturing the second photoresist patterns by simply exposing without an exposure mask. The method comprises the steps of: forming a first photoresist pattern on a semiconductor substrate on which a layer to be etched is formed; coating a composition for a mirror interlayer on the first photoresist pattern to form a mirror interlayer; forming a photoresist layer on the resultant; and forming a second photoresist pattern which is made by a scattered reflection of the mirror-interlayer and positioned between the first photoresist patterns, by exposing the photoresist layer to a light having energy which is lower than a threshold energy (Eth) of the photoresist layer without an exposure mask, and then developing the same.

  • Publication number: 20090144173
    Abstract: The present invention provides a method of generating a pseudo-3D user-adapted avatar by using artificial intelligence based on a method of converting a 2D image to the pseudo-3D image having visual and partial functions of a 3D model, and a method of performing a coordination simulation by applying the pseudo-3D coordination image generated by applying total clothes coordination information derived from the artificial intelligence to a user-adapted avatar. The pseudo-3D user-adapted avatar is generated by receiving primary size information and deriving secondary size information from an algorithm by using the primary size information. The pseudo-3D user-adapted avatar image suitable to the user's body shape is generated from the 2D standard avatar image.

  • Patent number: 7535467
    Abstract: An analog buffer, display device having the same and a method of driving the same are provided. The analog buffer applies an analog voltage to a load. The analog buffer includes a comparator and a transistor. The comparator is configured to compare an input voltage provided from an external device with the analog voltage applied to the load. The transistor is turned on to electrically charge the load when the analog voltage is lower than the input voltage or turned on to electrically discharge the load when the analog voltage is higher than the input voltage, and turned off when the analog voltage becomes substantially the same as the input voltage.
