DEVICE CONFORMITY CONTROL BY LOW TEMPERATURE, LOW PRESSURE, INDUCTIVELY COUPLED AMMONIA-NITROGEN TRIFLUORIDE PLASMA

The present disclosure generally relates to methods of removing oxides and oxide-containing layers from the surfaces of substrates. In one aspect, a method of processing a substrate comprises positioning a substrate in a process chamber, the substrate having an oxide layer thereon; introducing one or more process gases to an interior of the process chamber; ionizing the one or more process gases; exposing the oxide layer to the one or more ionized process gases, wherein the process chamber is maintained at a pressure less than about 50 mTorr during the exposing, and the substrate is maintained at a temperature within a range of about zero degrees Celsius to about 30 degrees Celsius during the exposing; and removing the oxide layer from the surface of the substrate.
