Title: Ion implanting uniformity predicting method
Inventor: ISOBE MICHIROU
IPC: G01T1/29
Filed: 1991-09-27
Abstract: PURPOSE:To precisely predict the ion implanting distribution of a target without executing the ion implantation by predicting the implanting uniformity using the distribution function determined from the relationship between the scan speed and beam profile. CONSTITUTION:When the beam spot of an ion beam 1 is sufficiently small, a CPU 2 processes beam current signals on each channel of a first and a second multi-point monitor 8, 15 and thereupon predicts the implanting uniformity. When the beam spot remains large, the beam profile is checked by the monitor 8 and/or monitor 15 or a beam profile monitor 14, and the checked beam profile and the beam current signals on the channels of the monitors 8, 15 are subjected to signal processing to serve for prediction of the uniformity. Accordingly this method is applicable even in a case the beam spot is large, with which the implantation amount distribution of target 13 can be determined from a calculation formula without requiring executing ion implantation into the target 13.

Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of a transmission characteristics by feeding back a part of a base band signal before it is inputted to an orthogonal modulator, comparing it with reference voltage, detecting error voltage and varying the reference voltage of the base band signal. SOLUTION: An in-phase component signal outputted from a loop filter 4-1 is branched before it is inputted to the orthogonal modulation circuit 5 and it is inputted to a comparator 20-1. An orthogonal component signal outputted from a loop filter 4-2 is branched and is inputted to a comparator 20-2. The outputs of the comparators 20-1 and 20-2 are inputted to level converters 2-1 and 2-2. When the DC level of the loop filter 4-1 fluctuates, the level converters 2-l and 2-2 input a part of the output of the loop filter 4-1 and reference voltage to the comparator 20-1. The comparator 20-1 outputs the error signal of the inputted signal and varies the reference voltage of the level converter 2-1. Thus, the output level of the in-phase component of the inputted base band signal is changed.
