A multi-layered semiconductor structure having an alignment feature for aligning
a lithography mask and that may be used in connection with a SCALPEL tool. The
present invention is particularly well-suited for sub-micron CMOS technology devices
and circuits, but is not limited thereto. The present invention advantageously
permits use of an electron beam source for both alignment and exposure of a lithography
mask on a semiconductor wafer. The present invention also advantageously enables
the formation of an alignment feature early (i.e., zero-level) in the semiconductor
device fabrication process.
