  • Patent number: 10534257
    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: 10529557
    Abstract: A substrate is positioned in exposure to a plasma generation region within a plasma processing chamber. A first plasma is generated within the plasma generation region. The first plasma is configured to cause deposition of a film on the substrate until the film deposited on the substrate reaches a threshold film thickness. The substrate is then exposed to ultraviolet radiation to resolve defects within the film deposited on the substrate. The ultraviolet radiation can be supplied in-situ using either a second plasma configured to generate ultraviolet radiation or an ultraviolet irradiation device disposed in exposure to the plasma generation region. The ultraviolet radiation can also be supplied ex-situ by moving the substrate to an ultraviolet irradiation device separate from the plasma processing chamber. The substrate can be exposed to the ultraviolet radiation in a repeated manner to resolve defects within the deposited film as the film thickness increases.

The labeling unit can be trained on prior call data and can identify one or more codecs used to encode the call, based on the call audio. The identification unit can utilize the characteristics of traversed networks and the identified codecs, and based on this information, the identification unit can provide a provenance fingerprint for the call. Based on the call provenance fingerprint, the detection system can identify, verify, or provide forensic information about a call audio source.

  • Patent number: 10515821
    Abstract: Various embodiments herein relate to methods and apparatus for etching a feature in a substrate. Often, the feature is etched in the context of forming a DRAM device. The feature is etched in dielectric material, which often includes silicon oxide. The feature is etched using chemistry that includes WF6. Although WF6 is commonly used as a deposition gas (e.g., to deposit tungsten-containing film), it can also be used during etching. Advantageously, the inclusion of WF6 in the etch chemistry can increase the etch rate of the dielectric material, as well as increase the selectivity of the etch. Unexpectedly, these benefits can be realized without any increase in capping.

  • Patent number: 10514598
    Abstract: Vacuum-integrated photoresist-less methods and apparatuses for forming metal hardmasks can provide sub-30 nm patterning resolution. A metal-containing (e.g., metal salt or organometallic compound) film that is sensitive to a patterning agent is deposited on a semiconductor substrate. The metal-containing film is then patterned directly (i.e., without the use of a photoresist) by exposure to the patterning agent in a vacuum ambient to form the metal mask. For example, the metal-containing film is photosensitive and the patterning is conducted using sub-30 nm wavelength optical lithography, such as EUV lithography.
