Title: Charged particle beam device
Inventor: OBARA ATSUSHI
IPC: H01J37/147
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To execute axis adjustment and astigmatism adjustment of an electro-optical system rapidly, stably and automatically, by detecting the difference between a charged particle beam and an optical axis of an electron lens based on an irradiation position of the charged particle beam obtained by a two-dimensional detector and shifting of a deflection range of the charged particle beam by a scanning deflector. SOLUTION: An electron beam irradiation position on an electron beam irradiation position detecting surface 41 is a position (Wi) proportional to a scanning deflection signal IDF, if the position is in the paraxial region of an objective lens 8, but an actual electron beam passing through the objective lens 8 is shifted to Wpi by receiving an influence by an intrinsic aberration of a lens. The difference between Wi and Wpi is affected by the position of incidence and the angle of incidence of the electron beam entering the objective lens 8. A waveform having the maximum scanning width symmetrical vertically with respect to zero is given, on the spot, to the waveform of the scanning deflection signal IDF to be given to a deflector.  The axis shift relative to the objective lens 8 and the axial angle shift relative to the optical axis of the electron beam are detected from the difference between the actual electron beam irradiation position at the time Wi and the electron beam irradiation position Wpi.

IPC: G02F1/1339
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To realize a manufacturing technique to manufacture a monochrome liquid crystal panel and a color liquid crystal panel in parallel keeping gaps between substrates nearly constant. SOLUTION: Optical characteristics of liquid crystal layers 13A, 13B are made almost equal to each other by setting their retardation values Δn.d (Δn is anisotropy in refractive index of liquid crystal molecules, d is thickness of a liquid crystal layer) nearly constant. Consequently, the values of anisotropy in refractive index are optionally differentiated between a color liquid crystal panel 10A and a monochrome liquid crystal panel 10B so as to equalize their retardation values. For example, if a liquid crystal having anisotropy in refractive index Δn=0.152 is used for the liquid crystal layer 13A of color liquid crystal panel 10A, the retardation is 0.456 by setting d=3 μm.  If a liquid crystal having anisotropy in refractive index Δn=0.114 is used for the liquid crystal layer 13B of monochrome liquid crystal panel 10B, the retardation is 0.456 by setting d=4 μm.
