    Abstract: The present disclosure generally relates to plasma assisted or plasma enhanced processing chambers. More specifically, embodiments herein relate to electrostatic chucking (ESC) substrate supports configured to provide independent pulses of DC voltage through a switching system to electrodes disposed through the ESC substrate support, or to electrodes disposed on a surface of the ESC, or to electrodes embedded in the ESC substrate support. The switching system can independently alter the frequency and duty cycle of the pulsed DC voltage that is coupled to each electrode. During processing of the substrate, the process rate, such as etch rate or deposition rate, can be controlled independently in regions of the substrate because the process rate is a function of the frequency and duty cycle of the pulsed DC voltage. The processing uniformity of the process performed on the substrate is improved.

    Abstract: Methods are provided for manufacturing well-controlled, solid-state nanopores and arrays thereof. In one aspect, methods for manufacturing nanopores and arrays thereof exploit a physical seam. One or more etch pits are formed in a topside of a substrate and one or more trenches, which align with the one or more etch pits, are formed in a backside of the substrate. An opening is formed between the one or more etch pits and the one or more trenches. A dielectric material is then formed over the substrate to fill the opening. Contacts are then disposed on the topside and the backside of the substrate and a voltage is applied from the topside to the backside, or vice versa, through the dielectric material to form a nanopore. In another aspect, the nanopore is formed at or near the center of the opening at a seam, which is formed in the dielectric material.
