  • Patent number: 8161667
    Abstract: Disclosed are an elastic sole member which optimizes between a shock absorbing function and repulsive elastic force, between which a tradeoff relationship exists, and a shoe with the elastic sole member. The elastic sole member includes a sole body which is upwardly inclined toward a back end thereof, and an elastic member comprised of a fixing piece inserted through and fixed in a space formed through an upwardly inclined back portion of the sole body, and an elastic plate extending from the fixing plate while it is downwardly inclined and having a first end exposed to the outside and a second end spaced apart from the sole body, in which the elastic sole member elastically contracts when external force is applied to a back portion of the sole body while the fixing piece serves as the elastic support axis and provides elastic recovery force when the external force is removed.

  • Publication number: 20100281709
    Abstract: The invention relates to a shoe provided with an outsole including an anti-distorting portion formed to extend from a rear portion to a front portion of the outsole to prevent the shoe from distorting, a shock-absorbing portion disposed at the rear portion of the outsole to absorb the external force applied to the heel portion of the wearer's foot when landing, and an elasticity-enhancing portion disposed at the front portion of the outsole in order to supplement actuating force using elastic force when leaving the ground. The shoe is advantageous in that it is possible to prevent the shoe from distorting while actions of landing and leaving the ground are repeated, to decrease the shock of the maximum load applied to the heel portion of the wearer's foot, and to supplement the actuating force with elastic recovery force when advancing.

  • Publication number: 20080227300
    Abstract: A method of manufacturing a semiconductor device prevents a pattern bridge phenomenon generated by a proximity effect between patterns and a thickness lowering phenomenon of the pattern. As a result, a length of the major axis required in characteristics of the device is secured to improve an electric characteristic and an overlapping margin. A photoresist pattern is formed to have a line/space type, thereby securing a DOF margin in comparison with a photoresist pattern of an island type.

  • Patent number: 7300880
    Abstract: A method of forming a fine pattern by a tri-layer resist process to overcome a bi-layer resist process is disclosed. When a fine pattern is formed using a silicon photoresist, a gas protection film is coated on a photoresist to prevent exhaustion of silicon gas generated from the photoresist in light examination of high energy. As a result, lens of exposure equipment may be prevented from being contaminated.

  • Patent number: 7238653
    Abstract: Cleaning solutions for photoresist are disclosed which are useful for cleaning a semiconductor substrate in the last step of development when photoresist patterns are formed. Also, methods for forming photoresist patterns using the same are disclosed. The disclosed cleaning solution comprises H2O as a solution, a surfactant which is phosphate-alcoholamine salt represented by Formula 1, and an alcohol compound. The disclosed cleaning solution has lower surface tension than that of distilled water which has been used for conventional cleaning solutions, thereby improving resistance to photoresist pattern collapse and stabilizing the photoresist pattern formation. wherein R, x, y, z, a and b are as defined in the specification.

  • Patent number: 7220679
    Abstract: A method for forming a pattern of a semiconductor device is disclosed which can increase the contact area between a photoresist and an anti-reflective film by performing an etching process on the anti-reflective film in a process of forming a photoresist pattern for a semiconductor device so as to form fine irregularities, thereby preventing collapse of a photoresist pattern. The disclosed method includes: (a) forming an organic anti-reflective film by coating an organic anti-reflective coating composition onto an upper portion of a layer to be etched, and performing a baking process thereto; (b) forming fine irregularities on the organic anti-reflective film by performing an etching process on the formed organic anti-reflective film; and (c) forming a photoresist pattern by coating a photoresist on the upper portion of the organic anti-reflective film, exposing the photoresist and then developing the same.
