IPC: H01L21/027
Filed: 1996-01-25
Abstract: PROBLEM TO BE SOLVED: To obtain a system for projecting an ion beam having a different profile to a sample by a constitution wherein the area of opening pattern of a mask is varied as required and a pattern ion beam of a different profile is projected to machine the sample. SOLUTION: An ion beam 3 emitted from an ion source 2 passes through an irradiation lens 4 and impinges on a mask 5 substantially normally thereto. The mask 5 determines an opening pattern through shields 6, 6' supported by supporting parts 7, 7'. Inching means 9, 9' disposed between fixed members 8, 8' and the supporting parts 7, 7' are telescoped by an electric signal and the shields 6, 6' are opened/closed to vary the opening area thus shaping an ion beam passing through the mask 5. The ion beam 3 passed through the mask 5 is temporarily condensed by means of a condenser lens 10 and can be projected to the surface of the sample as a parallel beam through a projection lens 11.

Abstract: PURPOSE: To provide a lighting system which has a high ratio of the occupation area of a mating part to the total area on the light emission side and can lessen the outside dimensions in proportion to the area of the data display region of a liquid crystal display device. CONSTITUTION: One end of a photo-guide plate 4 is bent to the side opposite the light emission surface 4d, and the inner end face 4c of this bent part of guide plate 4 is used as the light incident end face, and along it a light source 3 is installed. The light incident end face 4c provided in the non-mating part 4b of the guide plate 4 is formed not perpendicularly but aslant to the mating part 4a of the flat plate part. This permits the decrease of the light to emit from the end on the non-mating part 4b side in the mating part 4a of the guide plate 4 and allows the reduction of the bright lines to be generated at the end of the mating part 4a.  If the quantity of bright lines generated is made approx. the same as conventional, the part which has been blocked for the sake of bright lines can be used as the mating part to irradiate the data display region R to make possible further widening of the mating part 4a.
