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 10):
The system of  claim 9 , further comprising:\n an electrostatic lens upstream the beam-splitting device comprising at least one electrode plate, configured to collimate the electron beam; an aperture plate downstream the projection lens, configured to block the electrons scattered from the region; a substrate stage for placing the substrate, controllable to move the substrate for scanning in at least one of a step-and-scan mode and a continuous scan mode, wherein when the substrate stage is controlled to move in the step-and-scan mode, the beamlets are driven to scan the region when the substrate stage settles, and when the substrate stage is controlled to move in the continuous scan mode, the beamlets are driven to scan the region when the substrate stage moves at a constant speed; and an electronic control system for controlling parameters of at least one of the electron source, the electrostatic lens, the first multipole-field device, the beam-splitting device, the projection lens set, the deflector set, the objective lens set, the second multipole-field device, the substrate stage, the detector array, the processor, and the memory.
