Section: claims

1. A deflector array comprising:a plurality of deflectors, which deflect charged particle beams, arrayed on a substrate,wherein each of said plurality of deflectors includes a single opening formed in the substrate, and each of said plurality of deflectors including a pair of electrodes that oppose each other through the opening and being configured to deflect a single charged particle beam, andwherein said plurality of deflectors are arrayed such that a length of said pair of electrodes in a longitudinal direction thereof is not less than a distance between centers of two of said plurality of deflectors that are located nearest to each other, said plurality of deflectors being arrayed to form a checkerboard lattice, and two openings of the two of said plurality of deflectors overlapping in the longitudinal direction. 2. The deflector array according to claim 1, wherein said pair of electrodes are formed such that a distance between said pair of electrodes shortens from centers toward end portions of said pair of electrodes. 3. An exposure apparatus which exposes a wafer with a charged particle beam, the apparatus comprising:a charged particle source which emits the charged particle beam;a first electron optical system which forms a plurality of intermediate images of said charged particle source;a second electron optical system which projects the plurality of intermediate images formed by said first electron optical system onto the wafer; anda positioning apparatus which holds and positions the wafer,wherein said first electron optical system includes a deflector array defined in claim 1. 4. A method of manufacturing a device, the method comprising:exposing a wafer with a charged particle beam using an exposure apparatus defined in claim 3;developing the exposed wafer; andprocessing the developed wafer to manufacture the device. 5. The deflector array according to claim 1, wherein the deflector array includes deflectors with three rows and three columns.
