Abstract: An improved system and method for inspection of a sample using a particle beam inspection apparatus, and more particularly, to systems and methods of scanning a sample with a plurality of charged particle beams. An improved method of scanning an area of a sample using N charged particle beams, wherein N is an integer greater than or equal to two, and wherein the area of the sample comprises a plurality of scan sections of N consecutive scan lines, includes moving the sample in a first direction. The method also includes scanning, with a first charged particle beam of the N charged particle beams, first scan lines of at least some scan sections of the plurality of scan sections moving towards a probe spot of the first charged particle beam. The method further includes scanning, with a second charged particle beam of the N charged particle beams, second scan lines of at least some scan sections of the plurality of scan sections moving towards a probe spot of the second charged particle beam.

Abstract: A charged particle system generates a charged particle multi beam along a multi beam path. The charged particle system comprises an aperture array, a beam limit array and a condenser lens. In the aperture array are an array of apertures to generate from an up-beam charged particle source charged particle paths down-beam of the aperture array. The beam-limit array is down-beam of the aperture array. Defined in the beam-limit array is an array of beam-limit apertures for shaping the charged particle multi beam path. The condenser lens system is between the aperture array and the beam-limit array. The condenser lens system selectively operates different of rotation settings that define different ranges of beam paths between the aperture array and the beam-limit array. At each rotation setting of the condenser lens system, each beam-limit aperture of the beam-limit array lies on a beam path down-beam of the aperture array.

Abstract: A charged particle system may include a first charged particle beam source provided on a first axis, and a second charged particle beam source provided on a second axis. There may also be provided a deflector arranged on the first axis. The deflector may be configured to deflect a beam generated from the second charged particle beam source toward a sample. A method of operating a charged particle beam system may include switching between a first state and a second state of operating a deflector. In the first state, a first charged particle beam generated from a first charged particle beam source may be blanked and a second charged particle beam generated from a second charged particle beam source may be directed toward a sample. In the second state, the second charged particle beam may be blanked and the first charged particle beam may be directed toward the sample.

Abstract: A mail transmission system and method is disclosed, where a push mail server stores a mobile terminal identification and email-box information in an email server bound to the identification. The push mail server further retrieves an email from the email-box in the email server and converts the email into a mobile network message, and transmits the mobile network message and the mobile terminal identification bound to the email-box to a mobile network server. The mobile network server transmits the received mobile network message to a corresponding mobile terminal according to the received mobile terminal identification. A push mail server, a mobile mail receiving/sending system and a method for sending and receiving a mail by a mobile terminal are disclosed. The technical solutions of various embodiments of the invention enable a mobile terminal to receive and send emails based on an open communication protocol.
