Abstract:
Embodiments include a plasma processing method for cleaning polymer byproducts from interior surfaces of the plasma chamber. In an embodiment the plasma process may include processing a workpiece in a plasma processing chamber. Thereafter, the method may include removing the workpiece from the processing chamber. After the workpiece is removed, embodiments may include cleaning the plasma processing chamber with a cleaning process that includes a high pressure cleaning process, a first low pressure cleaning process, and a second low pressure cleaning process, wherein the second low pressure cleaning process includes applying a pulsed bias.
Abstract:
Embodiments described herein generally relate to a method of fabrication of a device structure comprising Group III-V elements on a substrate. A surface may be formed on a substrate and a Group III-V material may be grown from the surface to form a Group III-V device structure in a trench isolated between a dielectric layer. A final critical dimension of the device structure may be trimmed to achieve a suitably sized node structure.
