Title: Vibration control system
Inventor: EDOUIN EI SUROON
IPC: H03H17/02
Filed: 1989-12-15
Abstract: PURPOSE: To control the leakage optimally by connecting the output of a window opening system with the first input of a special digital filter and connecting the output of a pseudo random number generator(PRNG) with the second input thereof thereby establishing the amplitude and phase. CONSTITUTION: Output of a window opening system 10 is connected with the first input of a special digital filter 12 and the output of a PRNG 13 is connected with the second input thereof. A window selecting function generated from a window opening function generator 8 is not limited and an efficient window having small spectral leakage, e.g. Dorf Febischef window, can be selected. An opened drive data sequence functions as the digital representation of impulse response of the filter 12. Consequently, a drive data sequence characteristic of a reference having small spectral leakage and a Gaussian oscillation distribution as a result of filtering the output from the PRNG 13 is generated. The sequence has mean power regardless of the form of the window function. According to the system, the leakage can be controlled while establishing the amplitude and phase.

Abstract: PROBLEM TO BE SOLVED: To obtain an electron microscope in which the influence on a measurement of a contamination is reduced by computing the pattern size at a prescribed time on the basis of data on a time-dependent change in the pattern size accompanying irradiation with an electron beam. SOLUTION: When a sample base 46 is moved, a sample 47 is moved to a designated position, and an electron beam 43 scans the sample 47 by a polariscope 49. Secondary electrons 50 generated from the surface of the sample 47 are detected by a secondary- electron detector 51, they are amplified 52 so as to become a brilliance modulation signal for a display device 53, and the signal is stored once in a storage device 55. This procedure is repeated, a processing unit 56 draws out a detection signal at every scanning operation from the device 55, and a pattern size is computed by, e.g. a steepest ascent or descent method regarding a signal obtained by adding the definite number of scanning lines.  Then, the change with time in the pattern size is recorded, data on the change with time is extrapolated, and a size corresponding to the point of time of an electron-beam irradiation time of 0 is computed as a pattern size before irradiation with the electron beam. Thereby, the influence of a contamination is reduced, and the pattern size can be measured with high accuracy.
