Marty,

Probably not. Please find attached paper regarding face-to-face alignment.

                Subject:        [mems-talk] Is there a way to align two
sides of wafer

                Dear Mems group,

                I have a single side mask aligner.  Is there a method by
which this aligner
                can be used to align features on both sides of the wafer?

                Thanks for your assistance.

                Marty
