Title: Device and method for charged-particle beam lithography
Inventor: HATTORI SEIJI
IPC: H01L21/027
Filed: 1992-08-31
Abstract: PURPOSE:To cut a leakage beam so as to prevent the occurrence of a pattern defect by cutting a beam at a forming aperture by applying a voltage across blanking electrodes when a lithography circuit is temporarily stopped. CONSTITUTION:In the case of a lithography device adopting a continuous stage moving system, a stage is stopped for a vary short time when a deflection control circuit 33 temporarily stops its operations and the deflection of a beam is stopped at the time of turning the moving direction of the stage. When a voltage is applied across blanking electrodes 23 at the moment the stage is stopped, the cross over image of an electron gun moves in an aperture (beam limiting aperture) 27c for blanking and, as a result, the beam is cut and the current density on a sample becomes about 1/10<6>. Therefore, leakage of the beam can be reduced.

Title: System for supporting analysis of defective control of electronic computer
Inventor: KINOSHITA YOSHIAKI
IPC: G06F11/22
Filed: 1987-10-09
Abstract: PURPOSE:To shorten a real device control period needed for the confirmation of the device working by using a service processor supporting the analysis of a defect for study of the defect factors of an electronic computer to be checked. CONSTITUTION:When a defect occurs during confirmation of the working of a device carried out by an electronic computer 101 to be checked, the defect data 102 is sent to a service processor 103. The processor 103 codes the defect and calculates the re-executing time point from the coding result. At the same time, the processor 103 sets the stop conditions at the computer 101. Then the processor 103 gives an instruction to the computer 101 for re-execution via a re-execution control signal 105. Thus the computer 101 performs the re- execution and then stops by the stop conditions. Then the processor 103 transfers the internal information 106 on the computer 101 to an electronic computer 107 whose working is already confirmed. The computer 107 studies the factor of the defect by means of a defect analyzing tool.
