Abstract:
A substrate processing method for forming fully self-aligned vias. The method may be performed in a batch processing system that is capable of simultaneously processing multiple substrates, where the batch processing system includes a process chamber containing processing spaces defined around an axis of rotation in the process chamber. Each of the substrates contain a first surface and a second surface, and the method includes selectively forming SiO2 raised features on the first surface relative to the second surface.
