Title: Copying method for electrophotography
Inventor: ASAHINA YASUO
IPC: G03G21/10
Filed: 1988-03-03
Abstract: PURPOSE:To obtain a satisfactory cleaning effect even if a cleaning agent is used extending over a long period of time by setting the toner electrification quantity of the cleaning agent used for magnetic brush cleaning, to a prescribed quantity. CONSTITUTION:The toner electrification quantity (Q/M) of a cleaning agent used for magnetic brush cleaning is set to 20-90muc/g. When the Q/M is <=20muc/g, a residual toner comes not to be shifted easily to the cleaning agent (carrier) side, and a cleaning failure is generated. When the Q/M is >=90muc/g, the toner cannot be shifted to a collecting roller, the toner concentration of the cleaning agent rises and the Q/M becomes low, and also, a cleaning failure is generated.

IPC: G01B15/00
Filed: 1998-03-03
Abstract: PROBLEM TO BE SOLVED: To provide a method for measuring pattern dimensions, which can accurately make pattern matching to determine measuring point, by judging whether the SEM image satisfies predetermined pattern-shape criteria or not, and if it satisfies the criteria the pattern dimension is measured. SOLUTION: A template (a) of a resist pattern in which patterns are connecting mutually due to under-dose, a template (b) of a resist pattern in which the resist film is thinned due to over dose, and a template (c) that corresponds to a resist pattern obtained under best exposure conditions, are prepared, respectively. For an actual SEM image, the correlation factor on each of the template is calculated. When the correlation factor for template (c) is the highest, measurement of the dimension is made at the measuring point and moves to the next measuring point. If the correlation factor for the unresolved template (a) or (b) is the highest, measurement is not made but the procedure moves to the next measuring point.
