Patent
Pattern inspection apparatus with corner rounding of reference pattern data
TL;DR: In this article, a pattern inspection apparatus for comparing/collating a test target pattern with a corresponding design pattern to detect the presence/absence of a defect which is present in the test target patterns includes a bit pattern generating circuit for developing the data of the design pattern into bits.
Patent
Pattern inspection apparatus
TL;DR: In this article, a computer detects presence of a plurality of repeated pattern areas from layout information contained in the designed pattern data, reads the arrangement, the number, the dimension and the repeated pitch of the repeated pattern area, and automatically fetches an inspection area of the die-to-die comparison method.
Patent
Sample inspection apparatus and sample inspection method
TL;DR: In this paper, a method of inspecting a sample on which a pattern relating to fabrication of a semiconductor device is formed is presented, where a light radiation unit, an acquiring unit, storage unit, a template, a calculation unit, correction unit, defect detection unit, and an output unit are provided.
