Title: Device and method for generating numerical control data
Inventor: TAWARA HITOSHI
IPC: G05B19/4093
Filed: 1997-12-05
Abstract: PROBLEM TO BE SOLVED: To automatically determine the optimum work tool lowering position. SOLUTION: A contour graphic of a work area is taken-out from a graphic keeping file (S21) and, after that, max. permissible distance from the work area to the work tool lowering position is taken-out from original files (S22). Then, the counter graphic of the work area is extended outward by the max. permissible distance so as to obtain an extension area (S23) and, moreover, a work tool lowering prohibiting area is obtained (S24). The work tool lowering prohibiting area is excluded from the extension area so as to obtain an out-of- work area (S25). Then, the out-of-work area is reduced inward by the portion of the radius of a work tool so as to calculate a work tool lowering-enable area (S26).  After that, a minimum distance point between the work area and the work tool lowering-enable area is calculated so as to judge whether the minimum distance point can be calculated or not (S28). The calculated minimum distance point is set to the work tool lowering position when the answer is an affirmation (Yes) and the work area is displayed in a display part so as to execute an error processing at the time of a negation (No).

IPC: H01L21/68
Filed: 1991-12-10
Abstract: PURPOSE:To prevent production of non-implanted region by always confirming the wafer position during ion implantation. CONSTITUTION:When a wafer 1 is located at a predetermined position of a retainer 2, all ion beams are implanted into the wafer 1. Where the wafer position is deviated, any one of permeation holes 3 formed in a base seat 1 is exposed to the ion beams, by which the ion beams pass through the permeation hole. The ion beams which have passed there-through impinge upon an electrode 4 mounted on a rear face of the base seat, to permit passage therethrough of current. By monitoring the current flowing in the electrode plate, it is possible to know the positional deviation of the wafer 1 into which ion implantation is effected. The electrode 4 is mounted to a rear surface of the base seat 1 via an insulation bushing. When the current flowing in the electrode plate 4 is detected, ion implantation is stopped.
