Patent ID: 7083994

Claim:
A method of manufacturing a semiconductor device from a semiconductor body comprising: forming a first layer of masking material on a surface of the semiconductor body, wherein the first layer of masking material provides at least one topographical outline, an outline of a cleave marking region and an outline of at least one alignment or registration feature distinct from the at least one topographical outline; performing one or more processes to form at least one topographical feature from the at least one topographical outline, a cleave marking notch from the cleave marking region and at least one alignment or registration feature from the at least one outline of the at least one alignment or registration feature; forming an outline of a second cleave marking region in a second layer of masking material on the surface of the semiconductor body, where the second cleave marking region overlaps the notch formed in the cleave marking region; and performing an etching using a crystallographic etch to form a cleave marking feature, such that the at least one topographical feature, the cleave marking feature and the at least one alignment or registration feature are aligned with respect to one another, wherein the forming of the outlines of said cleave marking region and said second cleave marking region, and the forming of the outline of said at least one alignment or registration feature, are formed in a single lithographic step.
