Filed: 2007-01-31
Abstract: A method for repairing a photo mask is provided to reduce a process time and a manufacture cost by using an etchant for dissolving defects generated on the photo mask and vacuum-sucking the dissolved defects to remove them. An AFM(Atomic Force Microscope) tip(110) is moved to a residual defect included in a substrate(100). An etchant is dropped on the defect of the substrate. The etchant dissolves the defect. As the AFM tip is closed to a surface of the substrate, a water column is formed between the surface of the substrate and the AFM tip to allow the etchant to move to the surface of the substrate. A reactant(104) reacted with the etchant and the etchant are removed. The removing of the reactant and the etchant is performed by using the AFM tip. The defect is composed of chrome and the etchant is a chrome etchant. The AFM tip is made of a material which is not reacted with the etchant.

Filed: 2007-03-20
Abstract: A method for learning difference pressure when detecting soot in a differential sensor of a CPF(Catalyzed Particulate Filter) is provided to precisely determine the amount of soot accumulated in the filter by regarding a filter finishing with a regeneration operation as a monolith. A method for learning differential pressure when detecting soot in a differential sensor of a CPF comprises the step of determining whether soot is accumulated after the CPF is regenerated. The differential pressure of the regenerated CPF is detected. The step of determining whether soot is accumulated is performed by keeping the regenerated CPF for a predetermined time. The differential pressure of the CPF represents a sum of differential pressure of a monolith, differential pressure of soot and differential pressure of ash. The differential pressure of the monolith represents a soot-free differential pressure obtained before the soot is accumulated. The differential pressure of soot represents is obtained by excluding the soot-free differential pressure from differential pressure of the differential pressure sensor. The differential pressure of ash is calculated based on an ash factor.
