Abstract:
A method for imaging a surface of a substrate using a multi-beam imaging system includes: modifying an electron beam using a multipole-field device; generating beamlets from the electron beam using a beam-splitting device having multiple apertures; in response to projecting foci of the beamlets onto the surface, driving the beamlets using a deflector set to scan a region of the surface for receiving signals based on electrons scattered from the region; and determining an image of the region for inspection based on the signals. The multi-beam imaging system includes: an electron source; a first multipole-field device for beam shaping and beam aberration correction; a beam-splitting device; a projection lens set; a deflector set; an objective lens set; a detector array; a second multipole-field device; a processor; and a memory storing instructions to determine an image of the region for inspection based on the signals.

Claim (Index 9):
A system for imaging a surface of a substrate using multiple electron beamlets, comprising:\n an electron source, configured to generate an electron beam; a first multipole-field device for beam shaping and beam aberration correction, configured to modify a cross section of the electron beam from a first profile to a second profile; a beam-splitting device having multiple apertures, configured to generate and focus beamlets from the electron beam; a projection lens set, comprising at least one projection lens, configured to project foci of the beamlets onto a region of the surface; a deflector set, comprising at least one deflector, configured to drive the beamlets to scan the region; an objective lens set comprising at least one objective lens, configured to focus the beamlets into beam spots on the surface; a detector array, comprising at least one detector, configure to receive electrons scattered from the region to generate signals; a second multipole-field device comprising an electro-magnetic deflector, configure to deflect the electrons scattered from the region towards the detector set off a center axis of the beamlets; a processor; and a memory coupled to the processor, the memory configured to store instructions which when executed by the processor become operational with the processor to determine an image of the region for inspection based on the signals.
