A method (and semiconductor device) of fabricating a TFET device provides a source region having at least a portion thereof positioned underneath a gate dielectric. In one embodiment, the TFET includes an N+ drain region and a P+ source region in a silicon substrate, where the N+ drain region is silicon and the P+ source region is silicon germanium (SiGe). The source region includes a first region of a first type (e.g., P+ SiGe) and a second region of a second type (undoped SiGe), where at least a portion of the source region is positioned below the gate dielectric. This structure decreases the tunneling barrier width and increases drive current (Id).

The present disclosure provides reduced substrate coupling for inductors in semiconductor devices. A method of fabricating a semiconductor device having reduced substrate coupling includes providing a substrate having a first region and a second region. The method also includes forming a first gate structure over the first region and a second gate structure over the second region, wherein the first and second gate structures each include a dummy gate. The method next includes forming an inter layer dielectric (ILD) over the substrate and forming a photoresist (PR) layer over the second gate structure. Then, the method includes removing the dummy gate from the first gate structure, thereby forming a trench and forming a metal gate in the trench so that a transistor may be formed in the first region, which includes a metal gate, and an inductor component may be formed over the second region, which does not include a metal gate.

The present disclosure provides a method of fabricating a semiconductor device. The method includes forming a first gate structure and a second gate structure over a substrate. The first and second gate structures each include a high-k dielectric layer located over the substrate, a capping layer located over the high-k dielectric layer, an N-type work function metal layer located over the capping layer, and a polysilicon layer located over the N-type work function metal layer. The method includes forming an inter-layer dielectric (ILD) layer over the substrate, the first gate structure, and the second gate structure. The method includes polishing the ILD layer until a surface of the ILD layer is substantially co-planar with surfaces of the first gate structure and the second gate structure. The method includes replacing portions of the second gate structure with a metal gate. A silicidation process is then performed to the semiconductor device.
