Title: Working position correcting device for focused ion beam working device
Inventor: KAWAKAMI MEGUMI
IPC: H01J37/317
Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To reduce contamination of surfaces of a sample and the frequency of handling in the course of working, and perform work over a long time with reduced displacement of the working position, by providing a function for registering a specific number of marks for detecting displacement of the irradiating position of a focused ion beam and positional displacement of a stage, that may arise while the sample is worked. SOLUTION: A plurality of marks (1, 2, 3,..., n) are prepared for working position correction, and positions of these marks are stored. In the working, these marks are changed over from one to another at regular time intervals, while the position of each mark is detected, displacement of working position is calculated, the displacement of working position is reflected on the control of ion beam irradiation, and thereby the working position is corrected. The registration of the plurality of marks for working position correction and the changeover of marks used for position correction are enabled by a mark registering/control part 13 and by a mark changeover control part 14, respectively, each connected to a computer part 7. Contamination of a sample due to ion sputtering phenomenon and the frequency of handling by an operator can be thereby reduced.

Abstract: PURPOSE:To improve the surface smoothness of a magnetic disk and to prevent the crush of a magnetic head by hitting minute spheres of a material harder than projections present on the surface of the magnetic disk against the surface of the magnetic disk in a stage for finishing the surface of the magnetic disk so as to crush the projections. CONSTITUTION:The surface of a magnetic layer formed by baking a magnetic coating material on an Al substrate at a high temp. is finished by buffing, or the surface of a sputtered magnetic film of gamma-Fe2O3 or a magnetic metallic film is finished by polishing. Minute projections on the surface is not, however, perfectly removed by the surface finishing. Hard minute spheres 2 of Si3N4, TiN, stainless steel or the like larger than the minute projections are uniformly dropped line by line on the surface of the resulting magnetic disk from many outlets 4 of a vessel 3. The dropping distance H depends largely on the material and mass of the spheres 2. The dropped spheres 2 are hit against the projections to crush the soft projections and to push the hard projections into the magnetic film 1. Thus, the crush of a magnetic head is prevented.
