  • Patent number: 11649559
    Abstract: Implementations of the present disclosure generally relate to the fabrication of integrated circuits. More specifically, implementations disclosed herein relate to apparatus, systems, and methods for reducing substrate outgassing. A substrate is processed in an epitaxial deposition chamber for depositing an arsenic-containing material on a substrate and then transferred to a degassing chamber for reducing arsenic outgassing on the substrate. The degassing chamber includes a gas panel for supplying hydrogen, nitrogen, and oxygen and hydrogen chloride or chlorine gas to the chamber, a substrate support, a pump, and at least one heating mechanism. Residual or fugitive arsenic is removed from the substrate such that the substrate may be removed from the degassing chamber without dispersing arsenic into the ambient environment.

  • Publication number: 20220396785
    Abstract: Provided are methods and compositions for enriching cfDNA fragments from a biological fluid sample. A biological fluid sample, such as a urine sample, is collected and, in certain examples, pretreated before enrichment of the cfDNA. For the pretreatment, the sample is centrifuged to remove large cells and large cellular debris. As part of the pretreatment, the sample is also cleared of additional large cellular debris and excess volume by subjecting the sample to anion exchange chromatography and eluting bound DNA. Following any pretreatment of the sample, different concentrations an alcoholic solution are used—along with a mixture of DNA-binding particles and a chaotropic agent—to enrich the sample with cfDNA fragments having different sizes. For example, a biological sample can be enriched with small cfDNA fragments less than about 100 base pairs in length or large cfDNA fragments greater than about 100 base pairs in length.

  • Publication number: 20220333188
    Abstract: High-fidelity, high-throughput nucleic acid sequencing enables healthcare practitioners and patients to gain insight into genetic variants and potential health risks. However, previous methods of nucleic acid sequencing often introduce sequencing errors (for example, mutations that arise during the preparation of a nucleic acid library, during amplification, or sequencing). Provided herein are methods and compositions for sequencing nucleic acids. Further provided are methods of identifying an error in a nucleic acid sequence.

  • Publication number: 20220283029
    Abstract: One or more embodiments herein relate to methods for detection using optical emission spectroscopy. In these embodiments, an optical signal is delivered from the process chamber to an optical emission spectrometer (OES). The OES identifies emission peaks of photons, which corresponds to the optical intensity of radiation from the photons, to determine the concentrations of each of the precursor gases and reaction products. The OES sends input signals of the data results to a controller. The controller can adjust process variables within the process chamber in real time during deposition based on the comparison. In other embodiments, the controller can automatically trigger a process chamber clean based on a comparison of input signals of process chamber residues received before the deposition process and input signals of process chamber residues received after the deposition process.

  • Publication number: 20220268634
    Abstract: A method and apparatus for calibration non-contact temperature sensors within a process chamber are described herein. The calibration of the non-contact temperature sensors includes the utilization of a band edge detector to determine the band edge absorption wavelength of a substrate. The band edge detector is configured to measure the intensity of a range of wavelengths and determines the actual temperature of a substrate based off the band edge absorption wavelength and the material of the substrate. The calibration method is automated and does not require human intervention or disassembly of a process chamber for each calibration.
