Abstract: PURPOSE:To improve the accaracy of focusing and to brighten the picture on a finder, by forming innumerable finely projected or recessed parts arranged on the surface of a focusing screen to semispherical surfaces having heights and radii of curvature within specific ranges. CONSTITUTION:When innumerable finely rugged parts 11c and 11b are irregualr rly formed on the surface 11a of a flat and transparent glass plate 11 by scrubbing the surface with sand, and then, the glass plate 11 is soaked into a chemical etching reagent, the tip of the projected parts 11b is etched and become semispherically projecred parts 11b' and the glass plate 11 itself constitutes a focusing screen.

Abstract: PROBLEM TO BE SOLVED: To prevent the adhesion of particles to wafers so as to eliminate the occurrence of defective products due to the particles by capturing floating particles with electrode plates by impressing a larger potential difference than that of an electrostatic chuck stage to the earth upon the electrode plates. SOLUTION: After a wafer 8 is carried in a vacuum chamber 7 and placed on an electrostatic chuck(FSC) stage 3, a voltage having an absolute value larger than that of the voltage applied across the FSC stage 3 is applied across electrode plates 1 by operating a DC power source 4a with the signal of a sequence control section 2 several seconds before starting etching.
