Methods of fabricating an oxide layer on a semiconductor structure are provided herein. In some embodiments, a method of selectively forming an oxide layer on a semiconductor structure includes providing a substrate having one or more metal-containing layers and one or more non metal-containing layers to a substrate support in a plasma reactor; introducing a first process gas into the plasma reactor, wherein the first process gas comprises hydrogen (H2) and oxygen (O2); maintaining the structure at a temperature of less than about 100 degrees Celsius; and generating a first plasma from the first process gas to selectively form an oxide layer on the one or more non metal-containing layers, wherein the first plasma has a density of greater than about 1010 ions/cm3.
