    摘要: The present disclosure provides a method including providing a substrate having a first opening and a second opening on the substrate. A blocking layer is formed in the first opening. A second metal gate electrode is formed the second opening while the blocking layer is in the first opening. The blocking layer is then removed from the first opening, and a first metal gate electrode formed. In embodiments, this provides for a device having a second gate electrode that includes a second work function layer and not a first work function layer, and the first gate electrode includes the first work function layer and not the second work function layer.

    摘要: A method for fabricating an integrated circuit device is disclosed which includes providing a substrate having first, second, and third regions; and forming first, second, and third gate structures in the first, second, and third regions, respectively. The first, second, and third gate structures include a gate dielectric layer, the gate dielectric layer being a first thickness in the first gate structure, a second thickness in the second gate structure, and a third thickness in the third gate structure. Forming the gate dielectric layer of the first, second, and third thicknesses can include forming an etching barrier layer over the gate dielectric layer in at least one of the first, second, or third regions while forming the first, second, and third gate structures, and/or prior to forming the gate dielectric layer in at least one of the first, second, or third regions, performing an implantation process on the at least one region.

    摘要: The present disclosure provides an apparatus that includes a semiconductor device. The semiconductor device includes a substrate. The semiconductor device also includes a first gate dielectric layer that is disposed over the substrate. The first gate dielectric layer includes a first material. The first gate dielectric layer has a first thickness that is less than a threshold thickness at which a portion of the first material of the first gate dielectric layer begins to crystallize. The semiconductor device also includes a second gate dielectric layer that is disposed over the first gate dielectric layer. The second gate dielectric layer includes a second material that is different from the first material. The second gate dielectric layer has a second thickness that is less than a threshold thickness at which a portion of the second material of the second gate dielectric layer begins to crystallize.
