According to one embodiment, a pattern formation device that presses a template that includes a concave and convex part onto a transferring object and that forms a pattern in which a shape of the concave and convex part is transferred is provided. The device includes: a calculation part; an adjustment part; and a transfer. The calculation part calculates, using design information of the pattern, the distribution of force applied to the pattern at a time of releasing the template pressed onto the transferring object from the transferring object. The adjustment part adjusts forming conditions of the pattern in order to uniformly approach the distribution of force calculated by the calculation part. The transfer part transfers the shape of the concave and convex part to the transferring object according to the forming conditions adjusted by the adjustment part.

According to one embodiment, a mask pattern creation method includes extracting an area, in which a DSA material is directed self-assembled to form a DSA pattern, from a design pattern area based on a design pattern and information on the DSA material. The method also includes creating a guide pattern that causes the DSA pattern to be formed in the area based on the design pattern, the information on the DSA material, the area, and a design constraint when forming the guide pattern. The method further includes creating a mask pattern of the guide pattern using the guide pattern.

An embodiment provides a method of preparing a pattern. In the pattern preparing method, when mask patterns corresponding to on-substrate patterns are prepared to form the on-substrate patterns corresponding to design patterns, the mask patterns are prepared based on a correlation which needs to be satisfied between the design patterns so that a relation which same the correlation can be satisfied between the mask patterns corresponding to the design patterns.

A method of optimizing a semiconductor device manufacturing process according to an embodiment is a method of optimizing a semiconductor device manufacturing process in which a pattern based on circuit design is formed. The method of optimizing a semiconductor device manufacturing process according to the embodiment includes: at the time of calculation of a statistic amount based on a distribution of differences at a plurality of sites between a pattern formed by a first exposing apparatus in a first condition and a pattern formed by a second exposing apparatus in a second condition, calculating the statistic amount after applying weighting to the differences based on information on an electrical characteristic; and repeating the calculating with the second condition being changed, and selecting an condition in which the total sum becomes a minimum or equal to or less than a standard value as an optimized condition of the second exposing apparatus.

According to one embodiment, an evaluating apparatus includes a resist-pattern-data acquiring unit and an evaluating unit. The resist-pattern-data acquiring unit acquires resist pattern data having a plurality of feature values including at least two among a hole diameter measured concerning a pattern for hole formation in the resist pattern, an aspect ratio of the hole diameter, and a difference of hole diameters at a plurality of signal thresholds. The evaluating unit calculates an evaluation value using an evaluation function for evaluating whether a hole pattern formed on a processing target by using the pattern for hole formation is unopened and the resist pattern data and evaluates presence or absence of a risk that the hole pattern is unopened.
摘要:
A resist pattern (5) is formed in a dimension of a limitation of an exposure resolution over a hard mask material film (4) over a work film (3). The material film (4) is processed using the resist pattern (5) as a mask. A hard mask pattern (6) is thereby formed. Thereby a resist pattern (7), over a non-selected region (6b), having an opening (7a) through which a selection region (6a) in the mask pattern is exposed is formed. Only the mask pattern (6a) exposed through the opening (7a) is slimmed by performing a selection etching, the work film (3) is etched by using the mask pattern (6). A work film pattern (8) is thereby formed, which include a wide pattern section (8a) of a dimension width of the limitation of the exposure resolution and a slimmed pattern section (8a) of a dimension that is not more than the limitation of the exposure resolution.

摘要:
Mask data is generated from a design layout by executing a mask data process including optical proximity correction. A pattern is formed on the major surface of a test semiconductor substrate by using a mask prepared from the mask data. The dimensional difference between the design layout and the pattern is measured. The design layout is corrected, at a portion with the dimensional difference of the design layout, by the magnitude of the dimensional difference in a direction in which the dimensions of the pattern equal those of the design layout, thereby generating a corrected design layout. Corrected mask data is generated from the corrected design layout by executing the mask data process including the optical proximity correction. A pattern is formed on the major surface of a semiconductor substrate by using a corrected mask prepared from the corrected mask data.
