Methods and apparatus for processing semiconductor wafers with plasma processing chambers in a wafer track environment

摘要

A plasma chamber for performing semiconductor wafer processing within a wafer track system. The processing chamber may be configured as a thermal stack module within a wafer track cell for exposing a semiconductor wafer surface to a processing plasma. A showerhead electrode and wafer chuck assembly may be positioned within the processing chamber for effecting plasma-enhanced processing of the semiconductor wafer. Various types of supply gas sources may be in fluid communication with the showerhead electrode to provide a gaseous mixture that forms the desired plasma. The flow of gases may be regulated by a controller and a series of gas control valves to form and introduce the preselected gaseous mixture into the processing chamber as plasma that is exposed to the semiconductor wafer surface. The preselected gaseous mixture may be formulated for different semiconductor wafer processing operations such as surface prime treatment and bottom anti-reflective coating (BARC) deposition.
