titleOfInvention |
Semiconductor plasma processing equipment with wafer edge plasma sheath tuning ability |
abstract |
Embodiments of the present disclosure generally include methods and apparatuses to improve etch rate uniformity across the surface of a substrate by controlling the shape of the plasma sheath formed across the substrate, such as a semiconductor wafer, during plasma processing. Embodiments of the present disclosure will include adjustment of one or more plasma processing parameters, and/or adjustment of the configuration of process kit hardware that is very close to and/or supports the substrate during processing. Moreover, embodiments of the present disclosure may include replacing only a small number of consumable parts in the process kit hardware without venting the process chamber, while remaining parts of the process kit hardware are reused for long periods of time. will be. The replacement of consumable parts can be completed using an automated method of exchanging used parts without venting the process chamber. |
