We describe a new approach of microcontact printing which is based on a tri-layer processing. The replication process has four steps: (1) preparation of gold-PMMA-substrate by sputtering and spincoating deposition; (2) pattern transfer with alkanethiol molecules from a PDMS stamp to gold; (3) wet etching of gold and (4) reactive ion etching of under-layer PMMA. By this method, we succeeded in fabricating microstructures in PMMA resist which are suitable for further hard material pattern transfers, thereby providing an enhanced process compatibility with most of microfabrication steps
