IPC: G03F1/84
Filed: 1990-07-13
Abstract: PURPOSE:To detect a defect of a body to be inspected by applying a coherent light to the body and, processing and blocking the diffraction light by a spatial filter mechanism. CONSTITUTION:A coherent light radiated from a light source 3 is formed into a parallel light by an optical lens 5 through a half mirror 4, and applied onto the surface of a semiconductor wafer 2. Since IC chips are regularly arranged on the semiconductor wafer 2, the wafer 2 acts like a diffraction grating, and generates the diffraction light. The diffracted light is condensed by the optical lens 5, reflected by the half mirror 4 and is incident on a spatial filter mechanism 10. Rods 16, 17, 19,... 26 of the spatial filter mechanism 10 are spaced a distance corresponding to that of point images. Therefore, the point image is blocked by the rods 16, 17, 19,... 26. However, if there is a flaw on the surface of the semiconductor wafer 2, the scattering light due to the flaw is not blocked by the rods 16, 17, 19,... 26, but is allowed to pass therethrough.

Filed: 1994-08-09
Abstract: PURPOSE:To produce an inexpensive optical fiber array by an easy and practicable method by making the length in the optical axis direction of an array substrate shorter than the length of a fixing substrate. CONSTITUTION:A non-coated optical fiber 5 is coated with an adhesive 7 of a thermosetting type and is then disposed in the V-groove 8 of the aligning substrate 3 and is kept held and pressed by the fixing substrate 2 from a vertical direction. Next, the boundary part of a coated optical 4 and the non-coated optical fiber 5 is temporarily fixed by an adhesive 6 for temporary fixing before the non-coated optical fiber 5, the aligning substrate 3 and the fixing substrate 2 are fixed by the adhesive 7. The adhesive 7 of the thermosetting type is thereafter applied over the entire part not coated with the fixing substrate 2 and is thus fixed. Since the boundary part of the coated optical fiber 4 and the non-coated optical fiber 5 is temporarily fixed in such a manner, the load in the optical fiber aligning direction acting on the boundary part is prevented during the subsequent production stage.

Title: Polishing method and equipment
Inventor: NAKAJIMA TSUTOMU
IPC: B24B37/30
Filed: 1994-08-10
Abstract: PURPOSE:To improve the working uniformity on the surface of a substrate and suppress concurrently the generations of flaws in the rear surface of the substrate, by feeding a liquid to the clearance between a substrate holding head and the rear surface of the substrate, and by polishing the surface of the substrate in the state of the interposition of a flowing liquid film. CONSTITUTION:Through a hole 3 formed on a substrate holding head 2 made of quartz, a substrate 1 is vacuum-sucked in a stuck way by the head 2. Via a stainless steel disc 7 mounted on a rotary shaft 8, the quartz head 2 is rotated, and it is pressed against a rotary surface-plate 10 whereon an abrasive cloth 9 is stuck. When the head 2 is moved downward, nearly simultaneously with the contacting of the substrate 1 with polyurethane abrasive cloth 9, the vacuum- sucking of the substrate 1 is released, and a pure water 11 is fed to the hole 3. By this feeding the pure water 11, a flowing liquid film 12 is formed between the substrate 1 and the quartz head 2. The substrate 1 is held on the head 2 by the surface tension of the flowing liquid film 12. By the presence of the flowing liquid film 12, a pressure is applied uniformly from the quartz head 2 to the substrate 1, and thereby, the working uniformity in the surface of the substrate 1 is improved.
