20100304280 | METHOD OF FORMING A TEMPLATE, AND METHOD OF MANUFACTURING A SEMICONDUCTOR DEVICE USING THE TEMPLATE - A method of manufacturing a semiconductor device using a template on which a pattern is formed beforehand is disclosed. An error between a position of the pattern formed on the template and a reference position where the pattern is to be formed is obtained. An outer shape of the template is processed in accordance with the obtained error. The error of the template is corrected by distorting the template through application of pressure to a side face of the template whose outer shape is processed. The pattern is transferred onto a transfer layer formed on a semiconductor substrate by using the template in which the error is corrected. | 12-02-2010 |
20110097827 | PATTERN FORMATION METHOD AND A METHOD FOR MANUFACTURING A SEMICONDUCTOR DEVICE - In one embodiment, a pattern formation method is disclosed. The method can place a liquid resin material on a workpiece substrate. The method can press a template against the resin material and measuring distance between a lower surface of a projection of the template and an upper surface of the workpiece substrate. The template includes a pattern formation region and a circumferential region around the pattern formation region. A pattern for circuit pattern formation is formed in the pattern formation region and the projection is formed in the circumferential region. The method can form a resin pattern by curing the resin material in a state of pressing the template. In addition, the method can separate the template from the resin pattern. | 04-28-2011 |
20110192300 | IMPRINT METHOD AND IMPRINT APPARATUS - According to one embodiment, an imprint method is disclosed. The method can include forming a liquid droplet of a transfer material with a volume greater than a predetermined reference volume by dropping the transfer material onto a major surface of a processing substrate. The method can include reducing the volume of the liquid droplet to be less than the reference volume by volatilizing the liquid droplet. In addition, the method can include filling the transfer material into a recess provided in a transfer surface of a template by bringing the liquid droplet having the volume reduced to be less than the reference volume into contact with the transfer surface of the template. | 08-11-2011 |
