Abstract:
Damaged surface areas of low-k dielectric materials may be efficiently repaired by avoiding the saturation of dangling silicon bonds after a reactive plasma treatment on the basis of OH groups, as is typically applied in conventional process strategies. The saturation of the dangling bond may be accomplished by directly initiating a chemical reaction with appropriate organic species, thereby providing superior reaction conditions, which in turn results in a more efficient restoration of the dielectric characteristics.
