摘要： The invention generally provides a ground shield for use in a physical vapor deposition (PVD) chamber. In one embodiment, a ground shield includes a generally cylindrical body comprising an outer wall, an inner upper wall, an inner lower wall having a diameter less than a diameter of the inner upper wall and a reentrant feature coupling the upper and inner lower walls. The reentrant feature advantageously prevents arching between the shield and target, which promotes greater process uniformity and repeatability along with longer chamber component service life.

摘要： Apparatus for supporting a substrate such as a semiconductor wafer in a process chamber to improve power coupling through the substrate. The apparatus contains a pedestal assembly and a pedestal cover positioned over the top surface of and circumscribing the pedestal assembly for electrically isolating the pedestal assembly. The pedestal cover reduces conductive film growth in the wafer process region. As such, RF wafer biasing power from the pedestal assembly remains coupled through the substrate during processing.

摘要： Fabrication of gallium nitride-based light devices with physical vapor deposition (PVD)-formed aluminum nitride buffer layers is described. Process conditions for a PVD AlN buffer layer are also described. Substrate pretreatments for a PVD aluminum nitride buffer layer are also described. In an example, a method of fabricating a buffer layer above a substrate involves pre-treating a surface of a substrate. The method also involves, subsequently, reactive sputtering an aluminum nitride (AlN) layer on the surface of the substrate from an aluminum-containing target housed in a physical vapor deposition (PVD) chamber with a nitrogen-based gas or plasma.

摘要： Embodiments include devices and methods for sputtering material onto a workpiece in a chamber which includes a plasma generation area and a target. A coil is positioned to inductively couple energy into the plasma generation area to generate a plasma. A body is positioned between the workpiece and the target to prevent an amount of target material from being sputtered onto the workpiece. The body prevents an amount of target material from being sputtered onto the workpiece. The body may act as a dark space shield and inhibit plasma formation between the body and the target. The body may also act as a physical shield to block sputtered material from accumulating on the workpiece.
