  • Three-dimensional memory device containing self-aligned bit line contacts and methods for forming the same
    Patent number: 11935784
    Abstract: A vertical layer stack including a bit-line-level dielectric layer and an etch stop dielectric layer can be formed over an array region. Bit-line trenches are formed through the vertical layer stack. Bit-line-trench fill structures are formed in the bit-line trenches. Each of the bit-line-trench fill structures includes a stack of a bit line and a capping dielectric strip. At least one via-level dielectric layer can be formed over the vertical layer stack. A bit-line-contact via cavity can be formed through the at least one via-level dielectric layer and one of the capping dielectric strips. A bit-line-contact via structure formed in the bit-line-contact via cavity includes a stepped bottom surface including a top surface of one of the bit lines, a sidewall segment of the etch stop dielectric layer, and a segment of a top surface of the etch stop dielectric layer.

  • Cancer cell death inducing agent having effects of potentiating anticancer drug against anticancer-drug-resistant cancer
    Patent number: 8946173
    Abstract: The present invention provides a drug capable of causing cancer cells to restore anticancer drug sensitivity in cases in which cancer has acquired resistance to an anticancer drug and inducing cell death in cancer cells. The present invention specifically provides a cancer cell death inducing agent comprising REIC/Dkk-3 DNA as an active ingredient and having effects of potentiating an anticancer drug for cancer cells having anticancer drug resistance.
