20120107748 | DRAWING APPARATUS AND METHOD OF MANUFACTURING ARTICLE - A drawing apparatus, that performs drawing on a substrate using an array of charged particle beams, includes a projection system and a controller. The projection system is configured such that the array includes a plurality of sub arrays arranged discretely on the substrate with a space between the sub arrays in a predetermined direction, and a first width of the space in the predetermined direction is n1/n2 times (each of n1 and n2 is a positive integer) a second width of the sub array in the predetermined direction. The controller is configured to control the projection system and a driving mechanism such that drawing is performed in order with the plurality of sub arrays for [n1+n2] sets of drawing regions that are shifted from one another by as much as [1/n2] times the first width so that drawing is performed for a shot region on the substrate. | 05-03-2012 |
20130052590 | DRAWING APPARATUS AND METHOD OF MANUFACTURING ARTICLE - A drawing apparatus performs drawing, with an array of charged particle beams, on shot regions arrayed on a substrate in a direction in parallel and with intervention of step movement of the substrate in the direction. The apparatus includes a driving device for relative movement between a stage and a charged-particle optical system in the direction. The optical system causes sub arrays (of charged particle beams), discretely arrayed in the direction, to be incident on the substrate, and includes deflectors configured to respectively deflect sub array sets each including at least one of the sub arrays. A controller controls the optical system and the driving device such that a region at one side of a boundary among the shot regions and a region at the other side are subjected to drawing not in parallel with a sub array existing over the boundary, but sequentially with intervention of the step movement. | 02-28-2013 |
20130175453 | DRAWING APPARATUS, METHOD OF MANUFACTURING ARTICLE, AND INFORMATION PROCESSING APPARATUS - The present invention provides a drawing apparatus including a plurality of drawing units each of which is configured to perform drawing on a substrate with a charged particle beam, a plurality of first processors configured to be selectively connectable to each of the plurality of drawing units, an information processor configured to determine, from the plurality of first processors, a first processor to be connected to a first drawing unit among the plurality of drawing units, based on drawing data, and a connection unit configured to connect the determined first processor to the first drawing unit. | 07-11-2013 |
20130199719 | DRAWING APPARATUS, AND METHOD OF MANUFACTURING ARTICLE - A drawing apparatus which performs drawing on a substrate with a plurality of charged particle beams includes: a blanking device configured to individually blank the plurality of charged particle beams; a scanning deflector configured to deflect the plurality of charged particle beams to scan the plurality of charged particle beams on the substrate; and a controller configured to generate a periodic signal to control a periodic deflection operation of the plurality of charged particle beams by the scanning deflector. The controller is configured to adjust an amount of deflection of the plurality of charged particle beams by the scanning deflector in a period of the periodic signal so that a scanning speed of the plurality of charged particle beams becomes a target speed. | 08-08-2013 |
20130264497 | DRAWING APPARATUS, DRAWING METHOD, AND METHOD OF MANUFACTURING ARTICLE - A drawing apparatus performs drawing overlaid with a shot formed on a substrate with a plurality of charged particle beams based on a plurality of drawing stripe data that constitute drawing data.
