摘要:
A pattern inspection method in which an image can be detected without an image detection error caused by an adverse effect to be given by such factors as ions implanted in a wafer, pattern connection/non-connection, and pattern edge formation. A digital image of an object substrate is attained through microscopic observation thereof, the attained digital image is examined to detect defects, while masking a region pre-registered in terms of coordinates, or while masking a pattern meeting a pre-registered pattern, and an image of each of the defects thus detected is displayed. Further, each of the defects detected using the digital image attained through microscopic observation is checked to determine whether its feature meets a pre-registered feature or not. Defects having a feature that meets the pre-registered feature are so displayed that they can be turned on/off, or they are so displayed as to be distinguishable from the other defects.

An operation assisting system enhances the operator's willingness to participate in energy-saving efforts. The operation assisting system stores information about the actual operation of operated equipment carried out by the operator, evaluates the stored operation information, and displays the results of evaluation. The evaluation results relate to the cost concerning the operated equipment, the cost of supplying energy to the operation target facility, the cost concerning the operated equipment, the amount of emission of carbon dioxide, nitride oxide, and global warming substances, the amount of primary energy consumption, the crude oil-converted amount of energy consumption, the amount of excess or shortage of supply of energy, or electric power quality.

The present invention provides an image detection system capable of picking up a high resolution image of the surface condition of a circuit pattern-formed wafer without being affected by steep pattern steps, discontinuous reflectance distributions and optically transparent substances which are formed after resist patterns are formed and removed. A defect detection apparatus using such an image detection apparatus is also provided by the invention. The present invention is implemented by a configuration comprising a scanning stage having a sample mounted thereon, an image pickup system for picking up a surface image of the sample, height detection means for detecting the surface height of the sample at plural points including two points which are respectively on the opposite sides of the image pickup position in the scanning direction, sample height calculation means for calculating the height of the sample at the image pickup position by using the detected heights and focusing means for focusing the image pickup system by using the calculated sample height.

In the present invention, a reference conductive layer and a first surface conductive layer are respectively provided on a surface and a back face of a first base film. The first base film includes a first via hole penetrating the first surface conductive layer. After a first electroless plating layer and a first conductive material are sequentially grown on a surface of the first base film, a first coating conductive layer composed of the first electroless plating layer, the first conductive material and the first surface conductive layer, is etched to have a reduced thickness. Then, the first coating conductive layer is patterned to form a first wiring layer. In this manner, a desired pattern width can be obtained even in the case where the first coating conductive layer is patterned by isotropic etching such as wet etching.

A method for recording information on a rewritable recording medium includes recording synchronizing signal information in a synchronizing signal portion on the medium, recording data information in a data portion of the medium after the synchronizing signal portion by forming marks in the data portion, and substantially randomly inverting the marks and spaces between the marks each time the information is recorded. The marks for particular areas of the medium are different in a physical property from other areas of the medium and data information is recorded in association with both ends of each of the marks. Upon rewriting of at least the recorded synchronizing signal information, a length of the synchronizing signal portion changes and a start position of the synchronizing signal portion changes, and wherein a change of the synchronizing signal information start position is smaller than a change of the length of the synchronizing signal portion.
摘要:
In size measurement of a semiconductor device, profiles of a pattern formed in a resist process are determined through an exposure/development simulation in respect of individual different combinations of exposure values and focus values to form a profile matrix and scattered light intensity distributions corresponding to the individual profiles are determined through calculation to form a scattered light library, thereby forming a profile library consisting of the profile matrix and scattered light library. A scattered light intensity distribution of an actually measured pattern is compared with the scattered light intensity distributions of the scattered light library and a profile of profile matrix corresponding to a scattered light intensity distribution of scattered light library having the highest coincidence is determined as a three-dimensional shape of the actually measured pattern.
摘要:
An image condition is judged based on a mean value and a standard deviation of a feature quantity of an image, and image correction information in the image condition is created based on the mean value and the standard deviation, to thereby correct the image, based on the created image correction information. In this manner, parameters for the image correction processing are determined automatically and highly accurately corresponding to the feature quantity of the image, and the image correction processing is performed based on the parameters. Therefore, the image quality can be improved, while considerably reducing the labor of the operator who performs the image processing.
