Publication number: 20090260868Abstract: The printed circuit board includes the via formed with the electroplating layer unlike a conventional via formed with an electroless plating layer and an electroplating layer and having a cylindrical shape, and thus exhibits good interlayer electrical connection and high reliability of physical contact upon thermal stress caused by the variance in physical properties of material depending on changes in temperature. The via has no upper land, and thus a fine circuit pattern of the circuit layer can be formed on the via.Type: ApplicationFiled: June 27, 2008Publication date: October 22, 2009Applicant: SAMSUNG ELECTRO-MECHANICS CO., LTD.Inventors: Chang Gun Oh, Mi Sun Hwang, Suk Won Lee

Publication number: 20090255722Abstract: This invention relates to a printed circuit board having a landless via hole, including a circuit pattern formed on a via made of a first metal and having a line width smaller than the diameter of the via hole, in which the circuit pattern includes a seed layer made of a second metal and a plating layer made of a third metal, which is different from the second metal, and to a method of manufacturing the same. In the printed circuit board, the via has no upper land, thus making it possible to finely form the circuit pattern which is connected to the via, thereby realizing a high-density circuit pattern.Type: ApplicationFiled: June 26, 2008Publication date: October 15, 2009Applicant: SAMSUNG ELECTRO-MECHANICS CO., LTD.Inventors: Suk Won Lee, Chang Gun Oh, Mi Sun Hwang

Publication number: 20090155742Abstract: The present invention relates to a treatment method of the implant abutment surface to increase adhesion between the implant and its surrounding soft tissue, to prevent epithelial down-growth, to prevent bacterial infection, and to extend life-time of the implant and an implant surface-treated by the same. The method for treating surface of the dental implant or implant abutment is characterized by microgroove-formation having greater width and bottom width than the section diameter of a human gingival fibroblast and by additional acid-etching on the whole surface including ridges which used to be left as polished, so that filopodia is actively stretched out to increase adhesion between the implant and its surrounding soft tissues.Type: ApplicationFiled: June 30, 2008Publication date: June 18, 2009Applicant: INHA-INDUSTRY PARTNERSHIP INSTITUTEInventors: Suk Won Lee, Namsik Oh

Patent number: 7388712Abstract: A confocal scanning microscope using a Nipkow disk prevents deterioration of performance in an optical axis direction while maintaining a high measurement speed. The confocal scanning microscope includes a light source, an illuminating device to pass the light from the light source toward a certain direction, and two Nipkow disks each having slit-shaped apertures formed thereon such that the light incident from the illuminating device travels in a form of light which passed through a single aperture. In addition, the confocal scanning microscope includes a first optical system to form an image on a sample by the light passed through the Nipkow disks, and a second optical system to form a second image by the light reflected from the sample and passed through the Nipkow disks.Type: GrantFiled: April 15, 2005Date of Patent: June 17, 2008Assignee: Samsung Electronics Co., Ltd.Inventors: Suk-Won Lee, Kwang-Soo Kim, Dae-Gab Gweon, Dong-Kyun Kang, Hong-Ki Yoo, Seung-Woo Lee

Patent number: 7255478Abstract: A transporting apparatus which can horizontally transport a carrier using an air bearing of which a rotational degree of freedom is kept relative to a surface of a base. The transporting apparatus is movable along a surface of a base and includes an air bearing placed on a base, a connector connected to an upper part of the air bearing and provided with a supporter in a center thereof, the supporter having a flexure hinge structure to allow the air bearing to be freely rotated relative to the base, and the carrier supported by the supporter of the connector to be transported while keeping a level with respect to the surface of the base. With this configuration, a movement of the air bearing does not affect the carrier, thereby improving accuracy and reliability of the transporting apparatus.Type: GrantFiled: February 7, 2005Date of Patent: August 14, 2007Assignee: Samsung Electronics Co., Ltd.Inventors: Byung-il Ahn, Suk-won Lee, Se-kyong Song

Patent number: 7240434Abstract: A stage apparatus may include a first stage, a second stage movable with respect to the first stage, at least one flexure hinge to connect the first stage with the second stage, a plurality of actuators provided between the first stage and the second stage to push the first stage and the second stage and to be symmetric with respect to a center of the first stage and the second stage, and a controller to control the plurality of actuators to move one of the first stage and the second stage with respect to the other one of the first stage and the second stage. Thus, a position error of the stage can be reduced, which enables an ultra precision position control. Further, a piezoelectric driver using piezoelectric elements may be used as the actuator to decrease the position error more than a conventional driver such as a motor. The position error may be decreased to ±10 nm.Type: GrantFiled: February 7, 2005Date of Patent: July 10, 2007Assignee: Samsung Electronics Co., Ltd.Inventors: Suk-won Lee, Byung-il Ahn, Dong-woo Kang, Ki-hyun Kim, Dae-gab Gweon, Dong-min Kim
