Siddharth,

There are several MEMS companies that may provide aligned wafer bond service. Be
prepared ... Unless they have a microscope that will allow for ISA (inner
substrate alignment)  at lease one of your substrates will require a pattern on
the backside that is referenced to the opposite (bond) side.

You may want to contact IntelliSense    16 Upton Drive Wilmington, MA 01887
