摘要： A substrate holder has two holder constituting bodies, each having a plurality of columns arranged on an imaginary circle, and substrate holding sections that hold circumferential portions of respective substrates. The holder constituting bodies hold the substrates so that either their front surfaces or their back surfaces face upward with a substrate having an upward facing front and a substrate having an upward facing rear being alternately arranged in a vertical direction. At least one of the holder constituting bodies moves in the vertical direction to change the positions of the holder constituting bodies relative to each other. A distance between a first pair of vertically adjacent substrates with their respective front surfaces facing each other is set to ensure treatment uniformity, and to be larger than a distance between a second pair of vertically adjacent substrates with their respective back surfaces facing each other.

摘要： 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： A defect inspection method includes radiating an illumination slit-shaped beam having lights substantially parallel to a longitudinal direction to a substrate having circuit patterns in a direction inclined at a predetermined gradient relative to the direction of a line normal to the substrate and inclined at a predetermined gradient on a surface with respect to a group of main straight lines of the circuit patterns with its longitudinal direction oriented almost perpendicularly to a direction of a movement of the substrate. Scattered light reflected by a defect such as a foreign particle existing on the illuminated substrate is received and converted into a detection signal by using an image sensor, and defect judging is effected of an extracted a signal indicating a defect such as a foreign particle on the basis of the detection signal output.

摘要： A relative positional error is caused between an alignment mark and a device area on a mask due to an error inherent to the mask drawing apparatus, which causes an alignment error in the device area even when alignment upon exposure has no problem. Then, according to this invention, a relative positional error between the alignment mark and the device area on the mask is measured in an off line manner, the result of measurement is set upon exposure as a correction value to an exposure device thereby correcting the mask drawing error to reduce alignment errors in the device area.
