    摘要: A block film is formed on a region which includes a region of an insulating layer where a first hole is to be formed, and in which no second hole is to be formed, and a resist film having openings for forming the first and second holes is formed on the block film and insulating layer. Etching is performed by using the resist film as a mask, thereby forming the first hole in the block film and insulating layer, and the second hole in the insulating layer. The depth of the first hole from the upper surface of the insulating layer is smaller than that of the second hole, so the first hole does not reach the semiconductor substrate.

    摘要: A pattern forming method using two layers of resist pattern stacked one on the other has been disclosed. First, a first resist pattern is formed on a to-be-processed film. The first resist pattern is slimmed. On the slimmed first resist pattern and to-be-processed film, a second resist pattern is formed. With the first and second resist patterns as a mask, the film is processed.

    摘要: Disclosed is a method of setting a process parameter for use in manufacturing a semiconductor integrated circuit, comprising correcting a first pattern by using process parameter information to obtain a second pattern, the first pattern being one which corresponds to a design layout of the semiconductor integrated circuit, predicting a third pattern by using the process parameter information, the third pattern being one which corresponds to the second pattern and which is to be formed on a semiconductor wafer in an etching process, obtaining an evaluation value by comparing the third pattern with the first pattern, determining whether the evaluation value satisfies a preset condition, and changing the process parameter information when the evaluation value is found not to satisfy the preset condition.

    摘要: Disclosed is a method of manufacturing a photo mask comprising preparing mask data for a mask pattern to be formed on a mask substrate, calculating edge moving sensitivity with respect to each of patterns included in the mask pattern using the mask data, the edge moving sensitivity corresponding to a difference between a proper exposure dose and an exposure dose to be set when a pattern edge varies, determining a monitor portion of the mask pattern, based on the calculated edge moving sensitivity, actually forming the mask pattern on the mask substrate, acquiring a dimension of a pattern included in that portion of the mask pattern formed on the mask substrate which corresponds to the monitor portion, determining evaluation value for the mask pattern formed on the mask substrate, based on the acquired dimension, and determining whether the evaluation value satisfies predetermined conditions.
