Abstract: A program stored in a non-transitory medium and being executable by a computer of an information processing apparatus causes the computer to: execute a reading process for reading a plurality of pieces of text data arranged in one column or in one row; and be ready to accept a first operation by a user. In a case of accepting the first operation, the program causes the computer to execute: an obtaining process for obtaining a number of pieces of text objects to be included in specific label data; a generating process for extracting text data by the number of pieces obtained in the obtaining process, and for generating specific records each consisting of the number of pieces of text data; and an auto associating process for associating each text data included in each of the records with one of the text objects included in the specific label data.

Abstract: A method of forming a pattern with dots or holes arranged in a two-dimensional period by illuminating, with illumination light, a mask having a light-shielding portion pattern on a translucent substrate, and performing projection and exposure of an object to be exposed through a projection optical system. The illumination light is an effective light source of multipole illumination. A first exposure process is performed with the mask placed at a first position relative to the object to be exposed, and a second exposure process is performed with the mask placed at a second position. The mask has line patterns having lines with a line width a [m] arranged in parallel at a pitch of P. The line patterns are arranged in a mesh such that the line patterns intersect one another at 60° in three directions, and the illumination light is an effective light source of hexapole illumination.

Abstract: In an exposing method which illuminates, by illumination light, a mask having apertures arranged in matrix and a latticed light shielding portion, projects the mask on an object to be projected via a projection optical system, and thus forms a dark portion pattern image at a position conjugate in relation to intersections of a lattice of the light shielding portion, an available light source shape of the illumination satisfies a specific condition. Therefore, it is possible to exposure a two-dimensional periodic pattern to a theoretical limit pitch being the same as that of a one-dimensional periodic pattern, and it is also possible to secure a depth of focus sufficiently.
