Abstract: A method of properly correcting a base line. A concept of flexibility of a base line is introduced as an input index and a gravitation is presumed between the base line and signal data which is measured, thereby constructing a method of correcting the base line which changes gentler than a change in signal With respect to time in a peak area and which is sensitive to an area where a value of the signal data is small. A base line like a natural and smooth curve which isn't easily influenced by a local change in signal such as noise or the like can be set by an input of the flexibility.

Abstract: An electron beam drawing process of high throughput, coping with the changes in static distortion and dynamic distortion of a lower layer exposure apparatus or an optical reduction exposure apparatus. At least two marks formed in each chip formed on a wafer are detected for a predetermined number of chips, and the relation between the shape distortion of each chip in the wafer plane and the wafer coordinates is determined from the positions of the detected marks and the designed positions of the marks by a statistical processing. Patterns are drawn in all chips while correcting the patterns to be drawn on the individual chips, by using the relation between the determined chip shape distortion and the wafer coordinates. As a result, the superposition exposure with the lower layer can be achieved with a high throughput and with a high accuracy without any manual adjustment.

Abstract: When image information obtained on the basis of an NMR signal, e.g. MRI, is acquired, a radio frequency pulse is set so that a strong signal can be obtained particularly from a portion of interest among the sample. To accomplish this object, the occurrence of signals from portions of the sample other than the selected portion of interest is inhibited in advance of obtaining information (an image) of the sample. Various radio frequency pulses are then irradiated to the sample and a suitable radio frequency pulse is determined on the basis of the resulting signal.
