  • Patent number: 10217615
    Abstract: A plasma processing apparatus for processing semiconductor substrates comprises a plasma processing chamber in which a semiconductor substrate is processed. A process gas source is in fluid communication with the plasma processing chamber and is adapted to supply a process gas into the plasma processing chamber. A RF energy source is adapted to energize the process gas into a plasma state in the plasma processing chamber. Process gas and byproducts of the plasma processing are exhausted from the plasma processing chamber through a vacuum port. At least one component of the plasma processing apparatus comprises a laterally extending optical fiber beneath a plasma exposed surface of the component wherein spatial temperature measurements of the surface are desired to be taken, and a temperature monitoring arrangement coupled to the optical fiber so as to monitor temperatures at different locations along the optical fiber.

  • Patent number: 10197908
    Abstract: Disclosed are methods of generating a proximity-corrected design layout for photoresist to be used in an etch operation. The methods may include identifying a feature in an initial design layout, and estimating one or more quantities characteristic of an in-feature plasma flux (IFPF) within the feature during the etch operation. The methods may further include estimating a quantity characteristic of an edge placement error (EPE) of the feature by comparing the one or more quantities characteristic of the IFPF to those in a look-up table (LUT, and/or through application of a multivariate model trained on the LUT, e.g., constructed through machine learning methods (MLM)) which associates values of the quantity characteristic of EPE with values of the one or more quantities characteristics of the IFPF. Thereafter, the initial design layout may be modified based on at the determined quantity characteristic of EPE.

  • Patent number: 10141163
    Abstract: Systems and methods controlling ion energy within a plasma chamber are described. One of the systems includes an upper electrode coupled to a sinusoidal RF generator for receiving a sinusoidal signal and a nonsinusoidal RF generator for generating a nonsinusoidal signal. The system further includes a power amplifier coupled to the nonsinusoidal RF generator. The power amplifier is used for amplifying the nonsinusoidal signal to generate an amplified signal. The system includes a filter coupled to the power amplifier. The filter is used for filtering the amplified signal using a filtering signal to generate a filtered signal. The system includes a chuck coupled to the filter. The chuck faces at least a portion of the upper electrode and includes a lower electrode.

  • Publication number: 20180294140
    Abstract: A method for achieving sub-pulsing during a state is described. The method includes receiving a clock signal from a clock source, the clock signal having two states and generating a pulsed signal from the clock signal. The pulsed signal has sub-states within one of the states. The sub-states alternate with respect to each other at a frequency greater than a frequency of the states. The method includes providing the pulsed signal to control power of a radio frequency (RF) signal that is generated by an RF generator. The power is controlled to be synchronous with the pulsed signal.

  • Patent number: 10014192
    Abstract: A substrate processing system having a processing chamber for etching a layer on a substrate is provided. The system includes a chuck upon which the substrate is disposed during etching. The system also includes the chamber being divided into a plasma generating region and a substrate processing region by a separating plate structure. The system further includes a plasma source for generating plasma in the plasma generating region. The system further includes logic for introducing a first gas into the chamber, wherein the gas is suitable for etching the layer. The logic also allows the first gas to be present in the chamber for a period of time sufficient to cause adsorption of at least some of the first gas into the layer. The logic further replaces the first gas with an inert gas, generates metastables from the inert gas, and etches the layer with the metastables.
