Manufacturing Capability of Micro-Transfer Printing

Micro-Transfer printing is a mass transfer process that provides fast and precise assembly of micro-components onto non-native substrates. The process was originally conceived at the University of Illinois and has been developed at X-Celeprint. The process involves the fabrication of retrievable micro-components, elastomer stamp fabrication and transfer printing of the micro-components onto non-native substrates and their final interconnection. The transfer printing process enables a large array of micro-components to be transferred in one print , delivering an accuracy of +/- 1.5um 3 sigma and transfer yields exceeding 99%.
