Abstract

Embodiments of a semiconductor device having increased channel mobility and methods of manufacturing thereof are disclosed. In one embodiment, the semiconductor device includes a substrate including a channel region and a gate stack on the substrate over the channel region. The gate stack includes an alkaline earth metal. In one embodiment, the alkaline earth metal is Barium (Ba). In another embodiment, the alkaline earth metal is Strontium (Sr). The alkaline earth metal results in a substantial improvement of the channel mobility of the semiconductor device.
