  • Method for patterning a lanthanum containing layer
    Patent number: 11699621
    Abstract: Embodiments described herein relate to a method for patterning a doping layer, such as a lanthanum containing layer, used to dope a high-k dielectric layer in a gate stack of a FinFET device for threshold voltage tuning. A blocking layer may be formed between the doping layer and a hard mask layer used to pattern the doping layer. In an embodiment, the blocking layer may include or be aluminum oxide (AlOx). The blocking layer can prevent elements from the hard mask layer from diffusing into the doping layer, and thus, can improve reliability of the devices formed. The blocking layer can also improve a patterning process by reducing patterning induced defects.

  • IMAGE DIFFERENTIATED MULTIPLEX ASSAYS FOR DETECTION OF DNA MUTATIONS IN LUNG CANCER
    Publication number: 20230052147
    Abstract: Provided herein are methods and kits for detecting the presence of DNA and/or RNA mutations associated with cancer (e.g., lung cancer). The methods and kits employ microcarriers, each with a probe specific for a DNA or RNA mutation and an identifier unique to the probe sequence. Upon isolation and amplification of nucleic acids from a sample, hybridization of amplified DNA with a probe, specific for a DNA or RNA mutation, that is coupled to a microcarrier indicates the presence of the mutation in the sample. Since each microcarrier can be identified through detection of the identifier, multiplex screening assays are provided. Representative genes that can be screened for mutations include, e.g., KRAS, NRAS, PIK3CA, BRAF, EGFR, AKT1, MEK1, and HER2 for DNA mutations and/or ALK, ROS, RET, NTRK1, and cMET for RNA mutations.
