Title: Scanning efficiency improving device and method of ion implantation device
Inventor: EDWARDS PETER I T
IPC: H01J37/317
Filed: 1997-03-17
Abstract: PROBLEM TO BE SOLVED: To obtain a scanning efficiency improving device of an ion implantation device with improved scanning efficiency by detecting a time when the size of a sectional area of an ion beam incident to a substrate reaches zero when the ion beam incident to the substrate passes across an edge portion of the substrate and starting the subsequent operation. SOLUTION: A plural substrates 14 are mounted on a rotary wheel 11 and are rotated at the center of a gravity axis 21, while which the substrates is moved in an arrow 32 direction, and an ion beam 4 is incident to the substrate 14. When selected adjacent substrates A and B are at a position symmetrical to the ion beam 4, a residue 30 incident to the substrate 14 of the ion beam 4 is measured by means of a Faraday container 27. At a time when the ion beam 4 passes across an edge portion 24 of the substrates A and B simultaneously, the measured value reaches the maximum, and the ion beam 4 incident to the substrates A and B reaches zero. This time is detected and subsequent operation is started. Thus, time when the ion beam 4 is released from the substrate 14 is minimized, and the utilization efficiency of the ion beam 4 is substantially increased.

Abstract: PURPOSE:To perform optimum automatic heating-up control during the year by a method wherein the heating capacity is quantitatively controlled by correcting the heat quantity necessary for user in a unit period based upon the heat quantity in residual hot water in the previous unit period. CONSTITUTION:The titled control device is provided with a first calculating means (c), which calculates the required heating temperature based upon the water temperature detected by a water temperature detecting means (a) and the heat quantity necessary for user, a second calculating means (h), which calculates the daily heat quantity in residual hot water based upon the energizing hours measured by an energizing hour measuring means (g) and the required heating-up temperature calculated by the first calculating means (c) and a memorizing means to record the daily heat quantities in residual hot water calculated by the second calculating means (h) as a lot over a unit period. Heat quantity necessary for user in a unit period is corrected based upon the daily heat quantities of residual hot water, which are memorized in the memory means (i) as a lot over the previous unit period. For example, because, in the first unit period T1, the heat quantity of residual hot water for the fourth day is the minimum value Qmin1 and larger than the optimum marginal heat quantity of residual hot water Qg, the value of the expected heat quantity Qu1 necessary for the unit period T1 substracted by (Qmin1-Qg) is employed as the heat quantity Qu2 necessary for the following unit period T2.
