Title: Refresh control system
Inventor: ITO MIKIYA
IPC: G11C11/34
Filed: 1986-05-06
Abstract: PURPOSE:To prevent a CPU from the drop of processing capacity due to refreshing operation by refreshing banks other than an objective one and then refreshing the objective bank when an access request exists after the passage of a prescribed time, and when there is no request, refreshing all the bank. CONSTITUTION:When there are 20 memory addresses 2<0>-2<19>, 2<1>, 2<3> bits are decoded and the memory is divided into 4 sections to uniform access to respective banks. Receiving a signal indicating the passage of a regulated time from a counter 9, a control device executes the refreshing operation every memory banks 0-3. The control device is controlled by a processor 1, and when an access request is outputted from the processor to respective banks after the passage of the regulated time, the control device refreshes the banks other than an objective one and then refreshes the objective bank. If there is no access request from the processor, the control device holds the processor and refreshes all the banks after the passage of the prescribed time. Thereby, the simultaneous generation of both requests for access and refresh can be suppressed and the CPU can be prevented from the drop of processing capacity due to the refreshing operation.

Title: Scale correction method and device in cross-sectional observation by fib
Inventor: SUZUKI TOMOHITO
IPC: H01J37/28
Filed: 1995-04-27
Abstract: PURPOSE: To automatically correct the image of a specimen for distortion induced at cross-sectional observation made with an FIB by a method wherein an angle between a stage where the specimen is fixed and an ion beam which serves as an observation means is accurately measured, a correction value is calculated basing on the measured angle, and a corrected image is automatically projected onto a monitor. CONSTITUTION: A hole 14 is bored in a specimen 10 for cross-sectional observation made by an ion beam. The side face of the hole 14 can not be observed from just crosswise, so that it is observed from a direction which makes an angle with it. When a cut surface is observed, provided that an angle of inclination is θ, a length 1 is observed as 1 sinθ. This phenomenon does not occur in a lateral direction (inward direction of hole), so that the image of the side face of the hole 14 is observed as crushed in a horizontal direction (depthwise direction of hole) as a whole. For instance, if an angle θ of inclination is set to 30 deg., the image is observed half as long as an actual object. To correct an image for distortion, an angle θ of inclination is accurately measured, and an observation system is changed in scale by 1/sinθ in the horizontal direction.  By this setup, 1sinθ.(1/sinθ)=1, so that the image can be corrected for distortion.
