Title: Inspecting method for superimposition
Inventor: KAMON KAZUYA
IPC: G01N21/88
Filed: 1988-09-27
Abstract: PURPOSE:To enable highly accurate inspection of superimposition by observing a change in diffraction patterns formed at prescribed intervals (d) and d/2 on a semiconductor substrate and by utilizing an intensity ratio between an odd- order diffracted light and an even-order diffracted light. CONSTITUTION:Diffraction gratings 11 of a grating interval (d) are drawn on a wafer 10. A coherent light is made to fall on the gratings 11, diffracted lights generated from the gratings 11 are observed by a one-dimensional counter, and thereby a diffraction pattern is obtained. Next, the waver 10 is shifted slightly and then disposed at a position reached by a shift of d/2, and diffraction gratings of an interval (d) are drawn. Then diffraction gratings 12 are formed and a diffraction pattern is obtained. After the diffraction patterns thus obtained are standardized, an intensity ratio between an odd-order light and an even-order light is taken. More precise superimposition can be realized in proportion as this ratio (the intensity of the odd-order light/the intensity of the even-order light) comes near to 0.

Title: Disk device
Inventor: YAMAUCHI YOSHIAKI
IPC: G11B17/028
Filed: 1997-09-09
Abstract: PROBLEM TO BE SOLVED: To suppress vibration at the time of a low speed by holding correction balls for correcting the unbalance of a rotational moving section, thereby suppressing the rolling at the time of passing the resonance point of a rotation supporting system and releasing the rolling after passage through the resonance point. SOLUTION: A correction ball holding member 17 is formed as a leaf spring provided with a bend at the outer peripheral part (front end) formed by using an elastic member and presses the correction ball 16 in the outer peripheral direction of an orbit surface consisting of a toric groove. A unit mechanical chassis has the resonance point of the rotation supporting system based on the elasticity of vibration proof legs for mounting the chassis to a unit holder. The pressing force is set to the extent of slightly increasing the contact friction force of the correction balls 16 and the orbit surface in a region where the number of revolutions of a disk 1 is below the number of revolutions of the disk corresponding to the resonance point.  When the number of revolutions attains the number of revolutions exceeding the resonance point, centrifugal force acts on the bent front end of the leaf spring and the bent front end begins to be deformed in a horizontal direction. The correction balls 16 held thus far are released to roll on the orbit surface, by which the disk unbalance is corrected.
