    Abstract: Methods and apparatus for detecting ultraviolet light are provided herein. For example, an ultraviolet (UV) process chamber includes a vacuum window or a transparent showerhead; a UV light source disposed above one of the vacuum window or the transparent showerhead and configured to generate and transmit UV light into a process volume of the UV process chamber; and a first UV sensor configured to measure at least one of emissivity from the UV light source or irradiance of the UV light transmitted into the process volume and to transmit a signal corresponding to a measured at least one of emissivity from the UV light source or irradiance of the UV light to a controller coupled to the UV process chamber during operation.

    Abstract: Exemplary semiconductor processing chambers may include a substrate support positioned within a processing region of the semiconductor processing chamber. The chamber may include a lid plate. The chamber may include a gasbox positioned between the lid plate and the substrate support. The gasbox may be characterized by a first surface and a second surface opposite the first surface. The gasbox may define a central aperture. The gasbox may define an annular channel in the first surface of the gasbox extending about the central aperture through the gasbox. The gasbox may include an annular cover extending across the annular channel defined in the first surface of the gasbox. The chamber may include a blocker plate positioned between the gasbox and the substrate support. The chamber may include a ferrite block positioned between the lid plate and the blocker plate.

    Abstract: Techniques are disclosed for methods and apparatuses for reducing particle contamination formation in a high temperature processing chamber with a cooled gas feed block. The cooled gas feed has a body. The body has a main center portion having a top surface and a bottom surface. The body also has a flange extending outward from the bottom surface of the main center portion. A gas channel is disposed through the body. The gas channel has an inlet formed in the top surface of the main center portion and an outlet formed in the bottom surface of the main center portion. The body also has a center coolant channel. The center coolant channel has a first portion having an inlet formed in the top surface of the main center portion, and a second portion coupled to the first portion, the second portion having an outlet formed a sidewall of the flange.

    Abstract: Embodiments described herein generally relate to a plasma processing chamber and a detection apparatus for arcing events. In one embodiment, an arcing detection apparatus is disclosed herein. The arcing detection apparatus comprises a probe, a detection circuit, and a data log system. The probe positioned partially exposed to an interior volume of a plasma processing chamber. The detection circuit is configured to receive an analog signal from the probe and output an output signal scaling events present in the analog signal. The data log system is communicatively coupled to receive the output signal from the detection circuit. The data log system is configured to track arcing events occurring in the interior volume.

    Abstract: A method for fabricating a semiconductor layer within a plasma enhanced chemical vapor deposition (PECVD) apparatus. The PECVD apparatus includes a plurality of walls defining a processing region, a substrate support, a shadow frame, a gas distribution showerhead, a gas source in fluid communication with the gas distribution showerhead and the processing region, a radio frequency power source coupled to the gas distribution showerhead, and one or more VHF grounding straps electrically coupled to at least one of the plurality of walls. The VHF grounding straps provide a low-impedance current path between at least one of the plurality of walls and at least one of a shadow frame or the substrate support. The method further includes delivering a semiconductor precursor gas and a dopant precursor gas and delivering a very high frequency (VHF) power to generate a plasma to form a first layer on the one or more substrates.
