    Abstract: A semiconductor device and methods of formation are provided. A semiconductor device includes an annealed cobalt plug over a silicide in a first opening of the semiconductor device, wherein the annealed cobalt plug has a repaired lattice structure. The annealed cobalt plug is formed by annealing a cobalt plug at a first temperature for a first duration, while exposing the cobalt plug to a first gas. The repaired lattice structure of the annealed cobalt plug is more regular or homogenized as compared to a cobalt plug that is not so annealed, such that the annealed cobalt plug has a relatively increased conductivity or reduced resistivity.

  • Patent number: 9856480
    Abstract: The invention provides DNAzymes which are capable to silence the expression of EGFR at allele-specific level. These allele-specific DNAzymes against EGFR T790M mutation will knockdown the expression of EGFR T790M mRNA while keeping EGFR wild-type mRNA intact. Hence, these allele-specific DNAzymes against EGFR T790M mutation may overcome T790M-derived TKI resistance accompanied with lower unwanted side effects on normal cells in lung cancer patients.
