    摘要: An apparatus may include one or more measurement sensors, which may measure power coupled to one or more process stations of the apparatus. The apparatus may additionally include one or more analog-to-digital converters coupled to an output port of a corresponding one of the one or more measurement sensors, which may provide a digital representation of a RF signal measured by the one or more measurement sensors. A processor, coupled to a memory, may determine a crossing of the digital representation of the signal with a reference signal level and may thus determine a frequency content of the RF signal and the characteristic, which may permit the nulling out of phase lag of the one or more measurement sensors.

    摘要: A multi-signal radio frequency (RF) source includes an RF source; and a switch including an input in communication with an output of the RF source, a first output and a second output. The switch is configured to selectively connect the input to one of the first output and the second output. An RF generator in communication with the first output of the multi-signal RF source is configured to generate plasma in a processing chamber. A remote plasma generator in communication with the second output of the multi-signal RF source is configured to supply remote plasma to the processing chamber.

    摘要: In some examples, a substrate support assembly comprises a monolithic ceramic body, a heater element disposed within the monolithic ceramic body, and an RF antenna disposed within the monolithic ceramic body. One or more power lines supplies the heater element and the RF antenna. A lamellar structure is formed or included within the monolithic ceramic body, the lamellar structure including at least one layer having a thermal conductivity different than a thermal conductivity of the monolithic ceramic body.

    摘要: An in situ protective coating is deposited on surfaces of chamber components of a reaction chamber at high temperatures. The in situ protective coating may be deposited at a temperature greater than about 200° C. to provide a high quality coating that is resistant to certain types of halogen chemistries, such as fluorine-based species, chlorine-based species, bromine-based species, or iodine-based species. Subsequent coatings or layers may be deposited on the in situ protective coating having different etch selectivities than the underlying in situ protective coating. The in situ protective coating may be deposited throughout the reaction chamber to deposit on surfaces of the chamber components, including on chamber walls.

    摘要: Various examples include arrangements of semiconductor-processing tools. In one example, a semiconductor-processing tool includes multiple multi-station modules, each having multiple processing stations. At least some of the processing stations are organized in a diamond-shaped arrangement. A vacuum-transfer module is coupled to each of the multi-station modules. The vacuum-transfer module has one or more vacuum-transfer robots to transfer substrates to and from at least one of the multiple processing stations. At least one additional processing-station is located in the vacuum-transfer module. Other systems and apparatuses are disclosed.

    摘要: A system includes an electrode. The electrode includes a showerhead having a first stem portion and a head portion. A plurality of dielectric layers is vertically stacked between the electrode and a first surface of a conducting structure. The plurality of dielectric layers includes M dielectric layers arranged adjacent to the head portion and P dielectric portions arranged around the first stem portion. The plurality of dielectric layers defines a first gap between the electrode and one of the plurality of dielectric layers, a second gap between adjacent ones of the plurality of dielectric layers, and a third gap between a last one of the plurality of dielectric layers and the first surface. A number of the plurality of dielectric layers and sizes of the first gap, the second gap, and the third gap are selected to prevent parasitic plasma between the first surface and the electrode.
