| Zusammenfassung: | One embodiment relates to a charged-particle beam apparatus. The apparatus includes at least a source for generating the charged-particle beam, a first deflector, and a second deflector. The first deflector is configured to scan the charged-particle beam in a first dimension. The second deflector is configured to deflect the scanned beam such that the scanned beam impinges telecentrically (perpendicularly) upon a surface of a target substrate. Other embodiments are also disclosed. |
