Abstract
Methods for selective deposition are described herein. Further, methods for improving selectivity comprising an ammonia plasma pre-clean process are also described. In some embodiments, a silyl amine is used to selectively form a surfactant layer on a dielectric surface. A ruthenium film may then be selectively deposited on a conductive surface. In some embodiments, the ammonia plasma removes oxide contaminations from conductive surfaces without adversely affecting the dielectric surface.
