  • Patent number: 11315760
    Abstract: Embodiments of the present invention provide a plasma chamber design that allows extremely symmetrical electrical, thermal, and gas flow conductance through the chamber. By providing such symmetry, plasma formed within the chamber naturally has improved uniformity across the surface of a substrate disposed in a processing region of the chamber. Further, other chamber additions, such as providing the ability to manipulate the gap between upper and lower electrodes as well as between a gas inlet and a substrate being processed, allows better control of plasma processing and uniformity as compared to conventional systems.

  • Publication number: 20210396754
    Abstract: Effectiveness of a neoepitope-based immunotherapeutic composition against a tumor can be increased by predicting the surface presentation of the neoepitope bound to the HLA molecule of the tumor cell. Surface presentation levels of neoepitopes can be predicted by identifying any changes in omics data of the tumor cell that may affect the expression or surface trafficking of the HLA molecule and that may affect binding affinities of neoepitopes to the HLA molecule.

  • Publication number: 20210366722
    Abstract: Described is a process to clean up junction interfaces for fabricating semiconductor devices involving forming low-resistance electrical connections between vertically separated regions. An etch can be performed to remove silicon oxide on silicon surface at the bottom of a recessed feature. Described are methods and apparatus for etching up the bottom oxide of a hole or trench while minimizing the effects to the underlying epitaxial layer and to the dielectric layers on the field and the corners of metal gate structures. The method for etching features involves a reaction chamber equipped with a combination of capacitively coupled plasma and inductive coupled plasma. CHxFy gases and plasma are used to form protection layer, which enables the selectively etching of bottom silicon dioxide by NH3—NF3 plasma. Ideally, silicon oxide on EPI is removed to ensure low-resistance electric contact while the epitaxial layer and field/corner dielectric layers are—etched only minimally or not at all.

  • Patent number: 11069547
    Abstract: Apparatuses and methods for in-situ temperature measurement of a process chamber are described herein. A process chamber includes an infrared (IR) sensor mounted to the chamber wall. The IR sensor is mounted such that it can be oriented to receive an IR wave from targets within the process chamber through a view port in the chamber wall to detect a temperature of a surface inside the chamber, or to receive an IR wave from a target outside of the process chamber to detect an atmospheric temperature or a temperature of an exterior surface of the process chamber. As the orientation of the IR sensor is controllable to receive the IR wave from selected directions, it may be used to detect the temperature of various targets inside and outside the process chamber. The obtained temperature information is useful to improve overall chamber matching, processing throughput, and uniformity.

  • Publication number: 20210142864
    Abstract: Transcriptomics data from tumor tissue of patients diagnosed with metastatic breast cancer are clustered and associated with overall survival of the patients. A subset of genes from one of the cluster associated with poor outcome are used to generate a survival prediction model predicting a survival time based on expression levels of a plurality of genes. Using such generated survival prediction model, a survival time of a patient diagnosed with metastatic breast cancer can be predicted and a treatment regimen can be updated or generated based on the survival time.

  • Patent number: 10890497
    Abstract: The pressure pad which pressure-sensing fabric which is within a gasket and which measures the distribution of pressure on the gasket. Thus, the gasket protects the pressure-sensing fabric from damage due to water or mechanical trauma. The pressure pad includes multiple piezoresistive depositions of piezoresistive depositions ink or paste which act as individual pressure-sensing points. Conductive tracks between the piezoresistive depositions transmit the pressure measurements in the form of electrical signals. The pressure-sensing fabric is connected to a controller and transmits pressure measurements to the controller. Algorithms stored on the controller create a map of absolute mechanical loading to each pressure-sensing point of the pressure pad. The gasket may be mounted beneath a toilet or between plumbing joints. The pressure pad may detect weaknesses in the gasket, a toilet user's weight, a weight of excrement added to the toilet, or a toilet user's posture.

  • Patent number: 10846470
    Abstract: A multi-user collaboration system. User-specific change markings are applied to a collaboration object. The user-specific changes to be presented are time-oriented, based on a time of a last view of the collaboration object. A plurality of users that have access to the collaboration object are identified. Time-ordered versions of the collaboration object are captured. Each captured version corresponds to changes made to the collaboration object by any of the users. When a request to view the collaboration object is received from a subject user, a method determines the latest version of the collaboration object and also determines the specific last accessed version of the collaboration object that was seen by the subject user. The two versions are compared, and the comparison changes are used to generate user-specific change markings. The collaboration object with the generated user-specific change markings is presented by rendering the user-specific change markings on respective user-specific devices.
