摘要:
A carrier substrate is provided with a layer of PDMS and curing agent on one side of the carrier substrate. The PDMS and curing agent can be arranged to receive and adhere to a lithographic substrate. The carrier substrate can be dimensioned such that the combined carrier substrate and lithographic substrate may be handled by a conventional lithographic apparatus.
摘要:
A method of measuring bonding quality of a bonded substrate having an upper substrate on top of a lower substrate, the method comprising etching one or more windows in the upper substrate such that overlay measurement alignment marks on the upper substrate may be seen by a measurement system and overlay measurement alignment marks on the lower substrate may be seen by the measurement system, using the measurement system to measure the positions of the overlay measurement alignment marks, determining the distance between corresponding overlay measurement alignment marks on the upper and lower substrates, and adjusting the determined distance to take into account an offset between the overlay measurement alignment marks on the upper substrate and the overlay measurement alignment marks on the lower substrate.
