Title: Reference mark detector for dynamic balance tester
Inventor: NISHIMURA KATSUYOSHI
IPC: G01M1/22
Filed: 1985-01-14
Abstract: PURPOSE:To achieve a higher working efficiency eliminating prerotation, by detecting a reference mark attached to the circumference of a sample during the rotation for measurement with a photocell to detect and memorize the peak thereof, which is utilized for indexing an unbalanced angle. CONSTITUTION:A sample W is rotated with a belt 2 being driven by a motor 1 to detect a reference mark S attached to the circumference thereof with a photocell 3. The output of the photocell 3 is introduced into two successive inversive amplifiers 4a and 4b and after the polarity thereof is unified in a specified direction with a switch 5, it is divided in two to be inputted into a peak detection circuit 6 and a comparator 7. The output of the peak detection circuit 6 is inputted into a memory circuit 9 by closing a switch 8 during the rotation for measurement to be a reference voltage signal of the comparator 7. The signal thus obtained is utilized for indexing an unbalance angle thereafter. Thus, the mark S can be detected during no more than one rotation without requiring prerotation and moreover, indexing can be done within subsequent one rotation.

Title: Method for collecting a very small quantity of contaminant on surface of semiconductor wafer and contaminant collecting apparatus using the same
Inventor: SHIMAOKA HARUKO
IPC: H01L21/66
Filed: 1998-01-14
Abstract: PROBLEM TO BE SOLVED: To enable analysis of a trace amount of contaminant on a surface of a semiconductor wafer with extreme high sensitively by using a trenched wafer as a contaminant collecting wafer, and increasing a contaminant collecting area to collect a trace amount of contaminant, with high yield. SOLUTION: A silicon wafer, a wafer oxidized with a surface, or a wafer formed with an SiO2 layer on a surface through chemical vapor deposition is formed as a trenched wafer with irregularities on a surface by photoetching. Since a wafer 4 is a trenched structure, a contaminant deposited area on the surface increases by several times. Then, a semiconductor process to be intended to detect contamination is processed by the trenched wafer 4, and a very small quantity of contaminant is deposited on the trenched wafer 4. Subsequently, a trace amount of the deposited contaminant 2 is analyzed by atomic absorption spectrophotometry and the like, and a trace amount of metallic element is detected.  As a result, a trace amount of contaminant which could not be detected until now can be detected, since the contaminant deposition becomes double or more by the increase of the deposition area which is doubled or more.

Abstract: PURPOSE: To obtain a gap with high accuracy by executing the structurization of a core rim having a layer existing above by a reactive ion etching treatment. CONSTITUTION: Slopes 4a, 5a, 6a are given at edges, by which etching is executed in such a manner that the magnetic fluxes from ferrite are concentrated to gap surfaces 8 to be formed. Since the layer is formed of this type, the critical size relating to the saturation to regulate the surface of the smallest part of the core rim through which the magnetic fluxes pass is made larger than the size at the boundary surface of the gap and the additive magnetic fluxes is foreseen through the core rim. The core rim 2 is provided with a winding groove after etching. The layer part 5 at the gap surfaces has the width equal to the required gap width (a) and since the width (b) of the layer part 6 is much wider, the gap width is regulated only by the layer part 5 while the extremely simple aligning means is used.  The layer part 5 of the direction perpendicular to the head surface 9 is much longer than the layer part 6, the layer part 6 regulates the lower limit of the group height while the extremely simple aligning means is used. The need for the exact alignment is thus eliminated.
