摘要:
A device manufacturing method includes a transfer of a pattern from a patterning device onto a substrate. The device manufacturing method further includes transferring a pattern of a main mark to a base layer for forming an alignment mark; depositing a pattern receiving layer on the base layer; in a first lithographic process, aligning, by using the main mark, a first mask that includes a first pattern and a local mark pattern, and transferring the first pattern and the local mark pattern to the pattern receiving layer; aligning, by using the local mark pattern, a second mask including a second pattern relative to the pattern receiving layer; andin a second lithographic process, transferring the second pattern to the pattern receiving layer; the first and second patterns being configured to form an assembled pattern.
