Patent number: 8653458Abstract: An inspection device carries out beam scanning on a stable scanning cycle by enabling flexible change of various scanning sequences according to inspection conditions thereof, and at the same time, eliminates as much unevenness as possible in scanning cycle which hinders stabilization of charging. A beam scanning scheduler schedules beam scanning based on an inputted scanning condition, and a programmable sequencer carries out beam scanning control according to a beam scanning schedule generated by the beam scanning scheduler. The scanning scheduler calculates scanning line reference coordinates on a scanning-line-by-scanning-line basis, based on the scanning condition, and issues a scanning cycle trigger. The programmable sequencer controls supply timing of the scanning line reference coordinates and a scanning position on an in-line pixel-by-pixel basis, based on line scanning procedure information and the scanning cycle trigger provided from the beam scanning scheduler.Type: GrantFiled: June 22, 2011Date of Patent: February 18, 2014Assignee: Hitachi High-Technologies CorporationInventors: Yoshiro Gunji, Shuji Kikuchi

Patent number: 8385627Abstract: When an inspection apparatus of a semiconductor device repeatedly executes computation of prescribed area data, such as image processing for detecting defects, procedures for commanding, data load, computation, and data store need to be repeated the number of times of the computation. This may impose a limitation on the speeding up of the operation. In addition, when performing parallel computation by a high-capacity image processing system for handling minute images, a lot of processors are needed, resulting in an increase in cost.Type: GrantFiled: August 9, 2006Date of Patent: February 26, 2013Assignee: Hitachi High-Technologies CorporationInventors: Tadanobu Toba, Shuji Kikuchi, Yuichi Sakurai, Wen Li
