Title: Method and system for inspecting defect in substrate
Inventor: TABATA TAKAHITO
IPC: G09G3/298
Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To defect a defect in a substrate by irradiating a region to be inspected, while inclining, from the direction for forming a step using a pair of irradiation optical systems, irradiating the region to be inspected from the direction parallel with the step forming direction using another irradiation optical system and then detecting the scattered light by means of an optical sensor. SOLUTION: A region to be inspected set on a rib plate 1 is irradiated from the opposite sides, while inclining against the step forming direction, by a rib inspection optical system 3 at a specified angle of inclination within a range between the upper surface of a step and the skirt part thereof. The region to be inspected is also irradiated from the direction parallel with the step forming direction by a bottom face inspection optical system 4 at a specified angle of inclination. Scattered light from the region to be inspected, irradiated by the rib inspection optical system 3 and the bottom face inspection optical system 4, is received by a CCD linear sensor and a defect in the rib plate 1 is detected at a detect inspecting section 6 based on the receiving signal.  A detect can be detected while avoiding scattering of light from the edges at the upper and side steps even for a rib plate 1 having significant irregularities using the scattering light from the rib inspection optical system 3 and a defect can be detected at the raised part on the bottom face and the skirt part using the scattering light from the bottom face inspection optical system 4.

Filed: 1999-05-12
Abstract: PROBLEM TO BE SOLVED: To eliminate the photorefractive effect in a calcium rare earth oxyborate crystal and to obtain a wavelength conversion device having excellent resistance against optical damages by incorporating elements of the 2a group in the periodic table by specified % or more. SOLUTION: The calcium rare earth oxyborate single crystal contains >=0.1 mol% of group 2a elements in the periodic table. The 2a group elements to be added to the calcium rare earth oxyborate crystal include one or more kinds of Mg, Ca, Sr and Ba, and especially by adding Mg, the changes in the optical characteristics of the crystal by irradiation with short wavelength light are significantly improved. Thereby, the resistance against optical damages is improved and the stability as a short wavelength light source can be significantly improved. The proportion of the elements added is preferably >=0.1 mol% in the crystal, however, when the elements are added by >=10 mol%, defects in the quality of the crystal such as an inhomogeneous refractive index are caused, so that the proportion is preferably <=10 mol%.
