Patent Number: 
Section: claims

1. 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, the apparatus comprising: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; anda connection unit configured to connect the determined first processor to the first drawing unit. 2. The apparatus according to claim 1, wherein the determined first processor is configured to correct the drawing data. 3. The apparatus according to claim 1, wherein the information processor is configured to determine the first processor to be connected to the first drawing unit, based on a size of a drawing area corresponding to the drawing data. 4. The apparatus according to claim 3, further comprising:a plurality of second processors respectively connected to the plurality of drawing units,wherein the determination unit is configured to determine the first processor to be connected to the first drawing unit if the size of the drawing area exceeds a tolerance associated with the second processor. 5. The apparatus according to claim 1, whereineach of the plurality of drawing units includes a deflector configured to blank the charged particle beam, andthe drawing data includes control data for the deflector. 6. The apparatus according to claim 1, whereineach of the plurality of drawing units includes a deflector configured to scan the charged particle beam on the substrate, andthe drawing data includes control data for the deflector. 7. A method of manufacturing an article, the method comprising:performing drawing on a substrate using a drawing apparatus;developing the substrate on which the drawing has been performed; andprocessing the developed substrate to manufacture the article,wherein the drawing apparatus includes a plurality of drawing units each of which is configured to perform drawing on a substrate with a charged particle beam, the apparatus including: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; anda connection unit configured to connect the determined first processor to the first drawing unit. 8. An information processing apparatus connected to 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, the drawing apparatus including a plurality of first processors configured to be selectively connectable to each of the plurality of drawing units, and a connection unit configured to connect one of the plurality of first processors to one of the plurality of drawing units, wherein the information processing apparatus is configured todetermine, 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, andcontrol the connection unit so that the determined first processor is connected to the first drawing unit.
