The present invention provides a drawing apparatus which performs drawing on a substrate with a charged particle beam based on drawing data generated from pattern data representing a circuit pattern to be drawn on the substrate, and mark data representing a mark to be drawn on the substrate, the apparatus including an obtaining unit configured to obtain information associated with a positioning accuracy of the charged particle beam relative to the substrate, a determination unit configured to determine a drawing region for the mark based on the obtained information, and a generation unit configured to generate the drawing data by combining the pattern data and the mark data such that the mark is drawn in the determined drawing region.

Drawing apparatus, and method of manufacturing article

A method of aligning an object including steps of detecting an image of a mark on the object with respect to each of a plurality of areas on the object, obtaining a position of the mark based on the detected image with respect to each image detected in the detecting step, extracting a feature of the mark based on the detected image with respect to each image detected in the detecting step, determining a correction value based on previously prepared information to relate the extracted feature to the correction value, with respect to each position obtained in the obtaining step, correcting the obtained position based on the correction value with respect to each position obtained in the obtaining step, and calculating a position of each of a plurality of areas on the object based on positions corrected in the correcting step.

Alignment method and parameter selection method

A method of aligning an object. The method includes the steps of detecting an image of a mark on the object, obtaining a position of the mark based on the detected image, extracting a feature of the mark based on the detected image, and correcting the detected position based on the extracted feature.

A positioning method of detecting a position of an object, fixed on a driving device, in a direction of height as a driving direction, by a surface position detector, while scanning the object in a direction perpendicular to the driving direction of the driving device and positioning and correction driving the object by the driving device to sequentially set the object at a predetermined position and a predetermined height. The method includes a step of monitoring a driving condition of the driving device in synchronism with a periodical detection performed by the surface position detector and a step of correcting a drive amount of the driving device on the basis of the periodical detection performed by the surface position detector and a result of the monitoring performed in the monitoring step. The correcting step includes the steps of (i) calculating a mean data of the drive amount by the driving device in one detecting period of the periodical detection performed by the surface position detector, on the basis of the result of the monitoring, and (ii) obtaining a correction amount of the driving on the basis of the mean data and the detection result of the surface position detector obtained in the one detecting period.
