Abstract:
In order to provide an imaging-recipe arranging or creating apparatus and method adapted so that selection rules for automatic arrangement of an imaging recipe can be optimized by teaching in a SEM apparatus or the like, the imaging-recipe arranging or creating apparatus in this invention that arranges an imaging recipe for SEM-observing a semiconductor pattern using a scanning electron microscope includes a database that receives and stores layout information of the above semiconductor pattern in a low-magnification field, and an imaging-recipe arranging unit which, on the basis of the database-stored semiconductor pattern layout information, arranges the imaging recipe automatically in accordance with the automatic arrangement algorithm that includes teaching-optimized selection rules for selecting an imaging point(s).
Abstract:
PROBLEM TO BE SOLVED: To provide an inspection device and an inspection method using a scanning electron microscope which detects an highly-accurate electron beam image and excludes limitation of an AD conversion element for a sampling rate as a subject matter. SOLUTION: A sampling signal is obtained by sampling an analog brightness signal formed by a secondary electron detector at a designated sampling rate. N digital values are added in sequence per every continuous N digital values included in the sampling signal, and the digital brightness signal at one Nth frequency of the sampling frequency is formed. Then, a digital signal made of digital values of the bit number same as the bit number of the sampling signal is formed by dividing each digital value of the digital brightness signal by N. An image signal wherein each digital value of the digital signal becomes one pixel is formed. COPYRIGHT: (C)2009,JPO&INPIT

PROBLEM TO BE SOLVED: To provide an image forming method and an electron microscope capable of accurately or effectively acquiring information required for comparison regarding an image forming method accompanying with comparison among images such as three-dimensional image construction and a device for forming such images. SOLUTION: In the image forming method for forming the image on the basis of the comparison among a plurality of images obtained by irradiation of electron beams through different inclined angles on a testpiece, a first transmission image obtained by the electron beam irradiated from the first direction and a second transmission image in a zone different from a peripherally blur zone caused by an inclination as a second direction are obtained, and the first transmission image can be searched by using the second transmission image.

Abstract:
PROBLEM TO BE SOLVED: To provide an LINAC improved by utilizing direct digital synthesis (DDS) techniques to obtain precise frequency and phase control and automated electrode voltage phase calibration; and to provide an HE ion implantation system using it. SOLUTION: A DDS controller 130 may be used on an implantation process using a multi-stage linear accelerator to synchronize the frequency and phase of the electric fields to each electrode within each stage of the accelerator. The DDS controller includes digital phase synthesis (DPS) circuits 138 for modulating the phase of the electric field to the electrodes, and a master oscillator that uses digital frequency synthesis or DFS 134 to digitally synthesize a master frequency and a master phase applied to each of the DPS circuits. This method for automatically calibrating phase and amplitude of the RF electrode voltage of each stage is provided as well. COPYRIGHT: (C)2008,JPO&INPIT
