    Abstract: The present disclosure provides a semiconductor cleaning system. The cleaning system includes a chamber to retain a cleaning solution, and a gigasonic frequency generator. The gigasonic frequency generator is configured to generate an electrical signal corresponding to a range of gigahertz frequencies. A transducer is configured to transform the electrical signal to a mechanical wave of pressure and displacement that propagates through the cleaning solution with oscillations within the range of gigahertz frequencies.

    Abstract: The present disclosure relates to an electro-chemical plating (ECP) process that provides for an isotropic deposition, and a related apparatus. In some embodiments, the disclosed ECP process is performed by providing a substrate into an electroplating solution comprising a plurality of ions of a material to be deposited. A periodic patterned signal, which alternates between a first value and a different second value, is applied to the substrate. When the periodic patterned signal is at the first value, ions from the electroplating solution affix to the substrate. When the periodic patterned signal is at the second value, ions from the electroplating solution do not affix to the substrate. By using the periodic patterned signal to perform electro-chemical plating, the deposition rate of the plating process is reduced, resulting in an isotropic deposition over the substrate that mitigates gap fill problems (e.g., void formation).

    Abstract: The present disclosure relates to a method and apparatus for performing a plasma enhanced ALD (PEALD) process that provides for improved step coverage. The process introduces a precursor gas into a processing chamber comprising a semiconductor workpiece. The first gas is ionized to from a plurality of ionized precursor molecules. A bias voltage is subsequently applied to the workpiece. The bias voltage attracts the ionized precursor molecules to the workpiece, so as to provide anisotropic coverage of the workpiece with the precursor gas. A reactant gas is introduced into the processing chamber. A plasma is subsequently ignited from the reactant gas, causing the reactant gas to react with the ionized precursor molecules that have been deposited onto the substrate to form a deposited layer on the workpiece.

    Abstract: A method of manufacturing semiconductor device includes forming a multilayer photoresist structure including a metal-containing photoresist over a substrate. The multilayer photoresist structure includes two or more metal-containing photoresist layers having different physical parameters. The metal-containing photoresist is a reaction product of a first precursor and a second precursor, and each layer of the multilayer photoresist structure is formed using different photoresist layer formation parameters. The different photoresist layer formation parameters are one or more selected from the group consisting of the first precursor, an amount of the first precursor, the second precursor, an amount of the second precursor, a length of time each photoresist layer formation operation, and heating conditions of the photoresist layers. The multilayer photoresist structure is selectively exposed to actinic radiation to form a latent pattern, and the latent pattern is developed by applying developer to the selectively exposed multilayer photoresist structure to form the pattern.

    Abstract: A chemical-mechanical polishing system has a first polishing apparatus configured to perform a first chemical-mechanical polish on a workpiece and a second polishing apparatus configured to perform a second chemical-mechanical polish on the workpiece. A rework polishing apparatus comprising a rework platen and a rework CMP head is configured to perform an auxiliary chemical-mechanical polish on the workpiece when the workpiece is positioned on the rework platen. A measurement apparatus measures one or more parameters of the workpiece, and a transport apparatus transports the workpiece between the first polishing apparatus, second polishing apparatus, rework polishing apparatus, and measurement apparatus. A controller determines a selective transport of the workpiece to the rework polishing apparatus by the transport apparatus only when the one or more parameters are unsatisfactory.
