Title: Automatic focusing method
Inventor: HATTORI SEIJI
IPC: G01B15/00
Filed: 1986-12-27
Abstract: PURPOSE:To make automatic focusing with high processing speed and little noise effect possible, by a method wherein marks formed on a sample are scanned by a charged particle beam after a current applied to a coil for a lens is set, cumulative sum values are calculated from waveform data higher than or equal to the threshold level, and a current to maximize the sum value is set as the exciting current of lens. CONSTITUTION:An edge of the protruding step mark of a sample 5 is scanned by an electron beam, a reflected electron signal is subjected to A/D conversion, averaging addition is performed by a circuit 10, and the data are written in a waveform storage memory 11. On the basis of the maximum value and the minimum value of the waveform, a suitable value is set as a threshold level, and fixed so as to cross the edge. From the waveform storage memory, the data are read out, and cumulative sum values are calculated by a circuit 15 from the data higher than or equal to the threshold. While the current value of the coil for focusing is constantly increased, the cumulative sum values are calculated. On the basis of the current values and the cumulative sum values, the relation between them is approximated by a method of least squares. From this result, the current value to maximize the cumulative sum value is calculated, and this value is set as the exciting current of the coil. Thereby, the processing speed can be increased, and the influence of noise can be decreased.
