Abstract
Field effect transistor (FET) devices having a heterogeneous/segmented channel region and methods for fabricating the same are provided. In one example, a fin-like field effect transistor (FinFET) device includes a substrate, a fin structure disposed on the substrate, a segmented channel region formed in the fin structure, two source/drain (S/D) regions separated by the segmented channel region, and a gate structure wrapping around the segmented channel region. The segmented channel region further includes multiple channel segments sequentially arranged in the segmented channel region, and the multiple channel segments include a first channel segment and a second channel segment. The first channel segment includes a first channel barrier material dispersed therein and has a first energy barrier, and the first energy barrier is at least 0.1 electron volts (eV) in a carrier flow path between the two S/D regions when the FinFET device is not activated for operation.
