Abstract:
A method may include providing a substrate having, on a first surface of the substrate, a low dielectric constant layer characterized by a layer thickness. The method may include heating the substrate to a substrate temperature in a range of 200° C. to 550° C.; and directing an ion implant treatment to the low dielectric constant layer, while the substrate temperature is in the range of 200° C. to 550° C. As such, the ion implant treatment may include implanting a low weight ion species, at an ion energy generating an implant depth equal to 40% to 175% of the layer thickness.
