Title: Method for inspecting mask in fabrication of semiconductor
Inventor: SUGIURA EMIKO
IPC: G03F1/84
Filed: 1995-04-28
Abstract: PURPOSE: To detect the defect of a mask stably through inspection of a transferred resist pattern by transferring the pattern using a negative resist. CONSTITUTION: A negative resist 7 is employed in an existing equipment for detecting the defect of a wafer pattern, and the defect of mask is inspected using a resist pattern transferred with lower quantity of exposure than an appropriate level. Since a signal from a pattern being transferred using a positive resist 3 contains only a weak signal from the bottom part of resist, presence of a signal from the end part of resist can not be determined and thereby a decision can not be made whether the hole pattern is detective or not. When the pattern is transferred using a negative resist 7, detection light from the end part and surface of the resist 7 and from the surface of a substrate 8 has sufficiently high reflection intensity and the profile of transfer pattern can be detected sufficiently.  With such method, the defect of a mask can be detected stably by inspecting a transferred resist pattern.

Title: Pulse noise absorbing system for centrifugal load vibration-generating device
Inventor: TOKIYAMA SATOSHI
IPC: B06B1/18
Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To allow no degradation in the performance of accumulator by shortening the length of the accumulator piping while the arrangement of accumulator does not enlarge the dead-angle range relative to a camera lens. SOLUTION: A vibration generating device 24 which, mounted to a suspension body on which a test body is loaded, applies a vibration to a vibration stage which centrifugally supports the test body comprises an oil-pressure generating source 26, vibration generating piston which cyclically moves under the oil pressure supplied from the oil-pressure generating source 26 to combine to the vibration stage, and accumulator 30 which holds a displacement body 31 centrifugally displacing under a part of the oil-pressure acting on the vibration generating piston and relaxes the pressure change of the oil pressure. Thus, the occupation volume of a structure member extending laterally (in the direction orthogonal to the centrifugal direction) on the vibration stage is reduced for enlarged free degree in design.  Since an oil-pressure chamber is in upper level of a centrifugal field, the length of accumulator piping is shorter, resulting in lighter structure which endures a strong centrifugal force.

Title: Air current type classifying device
Inventor: MAKINO NOBUYASU
IPC: B07B7/08
Filed: 1999-04-14
Abstract: PROBLEM TO BE SOLVED: To eliminate the toner fixation in a classifying chamber and to stabilize the swirling flow in the classifying chamber by specifying the ratio of the bore of a louver for admitting secondary air flow from a peripheral part and the bore of a louver fixing base for a fixing the louver. SOLUTION: The louver 9 which is an inlet port for inflow secondary air and the louver base 10 fixing the louver 9 are disposed in the peripheral part of the classifying chamber. IN the meantime, spiral flow is formed in the perpendicular direction of a fluid mixture simultaneously when the fluid mixture swirls in a tangent direction in accordance with the inflow of secondary air. If the bore R2 of the louver base 10 is made smaller than the bore R1 of the louver 9 at this time, the swirling flow is supported by the louver base 10 and turns to the swirling spiral flow of an assigned region. The bore ratio R1:R2 of the louver base 10 for fixing the louver 9 is, thereupon, set within a range of 1:1 to 0.8. If the ratio is below this range, the sufficient spiral flow cannot be obtained.  ON the other hand, if the ratio is above this range, the secondary air flow is disturbed and the sufficient swirling flow cannot be obtained.
