Claim Text:
1. An adjusting method of a pattern transferring plate, comprising: adjusting a parameter for laser irradiation in correspondence with thickness distribution of a substrate of the pattern transferring plate in which a pattern is formed on the substrate to form an altered portion within the substrate, wherein a height position of the altered portion is set such that a distance from a back surface of the substrate to the altered portion is constant and a height position of the altered portion is set such that a distance from the front surface of the substrate to the altered portion is different in correspondence with thickness distribution of the substrate to keep constant a transmission rate and a distortion amount of the altered portion by moving the pattern transferring plate up and down when laser light is emitted to the pattern transferring plate, or a height position of the altered portion is set such that a distance from the front surface of the substrate to the altered portion is constant and a height position of the altered portion is set such that a distance from the back surface of the substrate to the altered portion is different in correspondence with thickness distribution of the substrate to keep constant a transmission rate and a distortion amount of the altered portion by changing laser intensity or laser irradiation time.
