| 20110053362 | METHOD OF FORMING A MASK PATTERN, METHOD OF FORMING A MINUTE PATTERN, AND METHOD OF MANUFACTURING A SEMICONDUCTOR DEVICE USING THE SAME - A method of forming a mask pattern, a method of forming a minute pattern, and a method of manufacturing a semiconductor device using the same, the method of forming the mask pattern including forming first mask patterns on a substrate; forming first preliminary capping layers on the first mask patterns; irradiating energy to the first preliminary capping patterns to form second preliminary capping layers ionically bonded with the first mask patterns; applying an acid to the second preliminary capping layers to form capping layers; forming a second mask layer between the capping layers, the second mask layer having a solubility lower than that of the capping layers; and removing the capping layers to form second mask patterns. | 03-03-2011 |
| 20110201203 | METHODS OF FORMING A HOLE HAVING A VERTICAL PROFILE AND SEMICONDUCTOR DEVICES HAVING A VERTICAL HOLE - In a method of forming a hole, an insulation layer is formed on a substrate, and a preliminary hole exposing the substrate is formed through the insulation layer. A photosensitive layer pattern including an organic polymer is then formed on the substrate to fill the preliminary hole. An etching gas including hydrogen fluoride (HF) or fluorine (F | 08-18-2011 |
| 20110244689 | METHOD OF MANUFACTURING SEMICONDUCTOR DEVICE - A method of manufacturing a semiconductor device includes forming a first mask pattern on a substrate by using a material including a polymer having a protection group de-protectable by an acid, the first mask pattern having a plurality of holes; forming a capping layer on an exposed surface of the first mask pattern, the capping layer including an acid source; diffusing the acid source into the first mask pattern so that the protection group becomes de-protectable from the polymer in the first mask pattern; forming a second mask layer on the capping layer, the second mask layer separate from the first mask pattern and filling the plurality of holes in the first mask pattern; and forming a plurality of second mask patterns in the plurality of holes by removing the capping layer and the first mask pattern. | 10-06-2011 |
