SINGLE-CRYSTALLINE METAL FILMS

摘要

According to an example of the present invention, a physical vapour deposition method comprises depositing a metal seed layer on a substrate, wherein the seed layer being deposited under a first temperature of between 20% and 90% of a melting temperature of the metal, and depositing more of the metal on the seed layer at a second temperature, lower than the first temperature, until a continuous single-crystalline film of the metal is complete and has a thickness of 10-2000 nanometres.
