  • Dielectric layer and a semiconductor memory device including the dielectric layer as a capacitor dielectric layer
    Patent number: 11417516
    Abstract: Provided is a dielectric layer that has a rock salt structure in a room temperature stable phase. The dielectric layer is made of a compound having a chemical formula of BexM1-xO, where M includes one of alkaline earth metals and x has a value greater than 0 and not greater than 0.19. A semiconductor memory device also is provided that includes a capacitor composed of a lower electrode; a dielectric layer disposed on the lower electrode; and an upper electrode disposed on the dielectric layer, wherein the dielectric layer has a rocksalt structure in a room temperature stable phase and is made of a compound having a chemical formula shown below, BexM1-xO, where M comprises an alkaline earth metal and x has a value greater than 0 and not greater than 0.19.
