Methods and devices for enhancing mobility of charge carriers. An integrated circuit may include semiconductor devices of two types. The first type of device may include a metallic gate and a channel strained in a first manner. The second type of device may include a metallic gate and a channel strained in a second manner. The gates may include, collectively, three or fewer metallic materials. The gates may share a same metallic material. A method of forming the semiconductor devices on an integrated circuit may include depositing first and second metallic layers in first and second regions of the integrated circuit corresponding to the first and second gates, respectively.
