  • Patent number: 10854459
    Abstract: Generally, the present disclosure provides example embodiments relating to formation of a gate structure of a device, such as in a replacement gate process, and the device formed thereby. In an example method, a gate dielectric layer is formed over an active area on a substrate. A dummy layer that contains a passivating species (such as fluorine) is formed over the gate dielectric layer. A thermal process is performed to drive the passivating species from the dummy layer into the gate dielectric layer. The dummy layer is removed. A metal gate electrode is formed over the gate dielectric layer. The gate dielectric layer includes the passivating species before the metal gate electrode is formed.

  • Patent number: 10847518
    Abstract: A semiconductor substrate is provided. Active areas and trench isolation regions are formed. The active areas extend along a first direction. Buried word lines extending along a second direction are formed in the semiconductor substrate. Two of the buried word lines intersect with each of the active areas, separating each of the active areas into a digit line contact area and two cell contact areas. Buried digit lines extending along a third direction are formed above the buried word lines. An upper portion of the trench isolation region is removed to form an L-shaped recessed area around each of the cell contact areas. The L-shaped recessed area exposes sidewalls of the cell contact areas. An epitaxial silicon growth process is then performed to grow an epitaxial silicon layer from the exposed sidewalls and a top surface of each of the cell contact areas, thereby forming enlarged cell contact areas.
