摘要： Oxygen controlled PVD AlN buffers for GaN-based optoelectronic and electronic devices is described. Methods of forming a PVD AlN buffer for GaN-based optoelectronic and electronic devices in an oxygen controlled manner are also described. In an example, a method of forming an aluminum nitride (AlN) buffer layer for GaN-based optoelectronic or electronic devices involves reactive sputtering an AlN layer above a substrate, the reactive sputtering involving reacting an aluminum-containing target housed in a physical vapor deposition (PVD) chamber with a nitrogen-containing gas or a plasma based on a nitrogen-containing gas. The method further involves incorporating oxygen into the AlN layer.

摘要： A magnetron sputter reactor including an ion beam source producing a linear beam that strikes the wafer center at an angle of less than 35°. The linear beam extends across the wafer perpendicular to the beam but has a much short dimension along the beam propagation axis while the wafer is being rotated. The ion source may be an anode layer source having a plasma loop between an inner magnetic pole and a surrounding outer magnetic pole with anode overlying the loop with a closed-loop aperture. The beams from the opposed sides of the loop are steered together by making the outer pole stronger than the inner pole. The aperture width may be varied to control the emission intensity.

摘要： A dual-position magnetron that is rotated about a central axis in back of a sputtering target, particularly for sputtering an edge of a target of a barrier material onto a wafer and cleaning material redeposited at a center of the target. During target cleaning, wafer bias is reduced. In one embodiment, an arc-shaped magnetron is supported on a pivot arm pivoting on the end of a bracket fixed to the rotary shaft. A spring biases the pivot arm such that the magnetron is urged towards and overlies the target center. Centrifugal force at increased rotation rate overcomes the spring bias and shift the magnetron to an outer position with the long magnetron dimension aligned with the target edge. Mechanical stops prevent excessive movement in either direction. Other mechanisms include linear slides and actuators.

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.
