Process Capability and Elastomer Stamp Lifetime in Micro Transfer Printing

Elastomer stamp based micro assembly or micro-transfer printing is a practical method for heterogeneous integration of micro-scale devices onto non-native substrates. In this paper, we evaluate the effect of stamp lifetime on performance and assess the useful lifetime of a stamp, both key metrics for using this technology in a manufacturing environment. We also review the performance of micro transfer-printing in several applications where >99% print yields and precise placement has been demonstrated.
