Abstract:
A method for fabricating inter-metal oxide in semiconductor devices, comprising:providing a semiconductor substrate having a plurality of patterned conductive features;performing a high density plasma (HDP) operation that is configured to deposit an oxide layer over the plurality of patterned conductive features, the HDP operation including a deposition component and a sputtering component, the deposition component being driven by a deposition gas and the sputtering component being driven by a sputtering gas, and the HDP operation forming oxide pyramids over the plurality of patterned conductive features;closing the deposition gas to remove the deposition component from the HDP operation; andrunning the HDP operation with the sputtering gas to retain the sputtering component, the sputtering component being configured to substantially remove the oxide pyramids from over the plurality of patterned conductive features.
