Inventor: MASUTANI TAKESHI
IPC: G03B35/26
Filed: 2007-03-30
Abstract: <P>PROBLEM TO BE SOLVED: To provide an optical filter for enabling an observation of a stereoscopic image on a stereoscopic image display or an image for a viewer on a plurality of image display devices without unevenness felt by the viewer even if slits are arrayed so as to mix a plurality of different slit pitches, a stereoscopic image display device using it and a plurality of the image display devices.  <P>SOLUTION: A parallax barrier 1 mixes the slit pitches different from an ideal slit pitch. An average of the slit pitches is approximately equal to the ideal slit pitch. Shift regions at locations of the slits to a location of the ideal slit are distributed. The viewer recognizes no unevenness even if the slits are shifted to raise a difference in hue, saturation or brightness of the image due to the shift.  <P>COPYRIGHT: (C)2008,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To provide a flaw inspection device capable of suppressing the influence of scattered light from the roughness of a sample surface and a normal circuit pattern, and detecting a flaw or the like of the sample surface at high sensitivity by increasing the gain of the scattered light from the flaw or a foreign substance.  <P>SOLUTION: When a lens with a large NA value is used, the lens outer diameter is 10a and the angle between a rhombic optical system and a wafer is α1. When the elevation angle of a rhombic detection system is reduced in order to detect much flaw scattered light by reducing the scattered light from wafer surface roughness, surface roughness under an oxide film, and the circuit pattern, the elevation angle α2 becomes lower than α1, but the outer diameter 10b of the lens becomes shorter than the lens outer diameter 10a and the condensing capacity of the scattered light decreases. When the lens diameter is increased to 10c in order to improve the condensing capacity, the lens interferes with the wafer 7. By forming a lens from which interference part is removed, the aperture size of the lens can be made larger than 10b and the flaw inspection capacity and the lens performance are improved simultaneously while the low elevation angle α2 is kept.  <P>COPYRIGHT: (C)2009,JPO&INPIT
