摘要： A method for cleaning a processing chamber is provided. The method initiates with introducing a fluorine containing gaseous mixture into a processing chamber. Then, a plasma is created from the fluorine containing gaseous mixture in the processing chamber. Next, a chamber pressure is established that corresponds to a threshold ion energy in which ions of the plasma clean inner surfaces of the processing chamber without leaving a residue. A method for substantially eliminating residual aluminum fluoride particles deposited by an in-situ cleaning process for a semiconductor processing chamber and a plasma processing system for executing an in-situ cleaning process are also provided.

摘要： A plasma confinement ring assembly with a single movable lower ring can be used for controlling wafer area pressure in a capacitively coupled plasma reaction chamber wherein a wafer is supported on a lower electrode assembly and process gas is introduced into the chamber by an upper showerhead electrode assembly. The assembly includes an upper ring, the lower ring, hangers, hanger caps, spacer sleeves and washers. The lower ring is supported by the hangers and is movable towards the upper ring when the washers come into contact with the lower electrode assembly during adjustment of the gap between the upper and lower electrodes. The hanger caps engage upper ends of the hangers and fit in upper portions of hanger bores in the upper ring. The spacer sleeves surround lower sections of the hangers and fit within lower portions of the hanger bores. The washers fit between enlarged heads of the hangers and a lower surface of the lower ring. The spacer sleeves are dimensioned to avoid rubbing against the inner surfaces of the hanger bores during lifting of the lower ring.

摘要： A wafer handling mechanism is operated to place a wafer on a chuck. A chucking force is then applied to the wafer, whereby wafer support features of the chuck transfer a defect pattern onto a surface of the wafer. The surface of the wafer is analyzed by a defect metrology tool to obtain a mapping of the defect pattern transferred onto the surface of the wafer. A center coordinate of the chuck within a coordinate system of the wafer is determined by analyzing the defect pattern as transferred to the surface of the wafer. A spatial offset between the center coordinate of the chuck and the center of the wafer is determined. The spatial offset is used to adjust the wafer handling mechanism so as to enable alignment of the center of the wafer to the center coordinate of the chuck.
