Lamination of organic semiconductors

Abstract

Low temperature, ambient pressure processes are desired for fabrication of transistors on flexible polymer substrates. Lamination of semiconductors is such a process. The semiconductor is deposited on a donor substrate. The donor is positioned over a receiver substrate, which may be patterned with additional transistor elements. The semiconductor is transferred from the donor to the receiver by lamination.
