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 12):
The system of  claim 11 , wherein the multi-aperture plate further comprises:\n a third layer upstream the first layer and comprising third apertures, wherein the third apertures align with the respective second apertures and have third sizes larger than the first size and smaller than the respective second apertures, and wherein the size of a fifth aperture of the third apertures is larger than the size of a sixth aperture of the third apertures when the fifth aperture is closer than the sixth aperture to a center axis of the electron beam.
