Abstract: Methods and systems for process chamber qualification for maintenance process endpoint detection are provided. Sensor data collected by sensors of manufacturing equipment of a manufacturing system during performance of one or more initial maintenance operations of a maintenance process is obtained. The obtained sensor data is provided as an input to a machine learning (ML) model and one or more outputs of the ML model are obtained. The output(s) include a current state of the manufacturing equipment based on the performance of the initial maintenance operation(s). The current state represents a distance between the obtained sensor data and target sensor data associated with a final maintenance operation of the maintenance process. A set of subsequent maintenance operations of the maintenance process is determined based on the current state of the manufacturing equipment. Performance of the set of subsequent maintenance operations at the manufacturing equipment is initiated.

Abstract: Methods and systems for process chamber qualification for maintenance process endpoint detection are provided. Data collected by one or more sensors of a process chamber of a manufacturing system is identified. The identified data is collected during performance of initial maintenance operation(s) of a maintenance process. A current state of the process chamber is determined, based on the identified data, after the performance of the initial maintenance operation(s) based on the identified data. In response to a determination that the current state does not satisfy one or more chamber maintenance criteria, a set of subsequent maintenance operations to be performed to cause the current state of the process chamber to satisfy the criteria is identified. Performance of the set of subsequent maintenance operations is initiated at the process chamber.

Abstract: Methods form structures that include (among other components) semiconductor fins extending from a substrate, gate insulators contacting channel regions of the semiconductor fins, and gate conductors positioned adjacent the channel regions and contacting the gate insulators. Additionally, epitaxial source/drain material contacts the semiconductor fins on opposite sides of the channel regions, and source/drain conductive contacts contact the epitaxial source/drain material. Also, first insulating spacers are on the gate conductors. The gate conductors are linear conductors perpendicular to the semiconductor fins, and the first insulating spacers are on both sides of the gate conductors. Further, second insulating spacers are on the first insulating spacers; however, the second insulating spacers are only on the first insulating spacers in locations between where the gate conductors intersect the semiconductor fins.

Abstract: Described herein are nanosheet-FET structures having a wrap-all-around contact where the contact wraps entirely around the S/D epitaxy structure, thereby increasing contact area and ultimately allowing for improved S/D contact resistance. Other aspects described include nanosheet-FET structures having an air gap as a bottom isolation area to reduce parasitic S/D leakage to the substrate.

Abstract: Structures for a field-effect transistor and methods of forming a structure for a field-effect transistor. A first dielectric layer is deposited over a first gate structure in a first device area and a second gate structure in a second device area, and then planarized. A second dielectric layer is deposited over the planarized first dielectric layer, and then removed from the first device area. After removing the second dielectric layer from the first device area, the first dielectric layer in the first device area is recessed to expose the first gate structure. A silicide is formed on the exposed first gate structure.
