Alignment of multi-beam pattern tools includes generating a test pattern having multiple features with a multi-beam patterning tool, acquiring an image standard associated with a test pattern standard, acquiring an image of a portion of the test pattern, comparing the portion of the image of the test pattern to the image standard to identify one or more irregularities between the portion of the image of the test pattern and the image standard, and adjusting one or more beams of the multi-beam patterning tool based on the one or more identified irregularities between the portion of the image of the test pattern and the image standard. |
