    Abstract: A transistor and a method for forming the transistor are provided. The method includes performing at least one implantation operation in the transistor channel area, then forming a silicon carbide/silicon composite film over the implanted area prior to introducing further dopant impurities. A halo implantation operation with a low tilt angle is used to form areas of high dopant concentration at edges of the transistor channel to alleviate short channel effects. The transistor structure includes a reduced dopant impurity concentration at the substrate interface with the gate dielectric and a peak concentration about 10-50 nm below the surface. The dopant profile has high dopant impurity concentration areas at opposed ends of the transistor channel.

    Abstract: In a method of manufacturing a gate-all-around field effect transistor, a trench is formed over a substrate. Nano-tube structures are arranged into the trench, each of which includes a carbon nanotube (CNT) having a gate dielectric layer wrapping around the CNT and a gate electrode layer over the gate dielectric layer. An anchor layer is formed in the trench. A part of the anchor layer is removed at a source/drain (S/D) region. The gate electrode layer and the gate dielectric layer are removed at the S/D region, thereby exposing a part of the CNT at the S/D region. An S/D electrode layer is formed on the exposed part of the CNT. A part of the anchor layer is removed at a gate region, thereby exposing a part of the gate electrode layer of the gate structure. A gate contact layer is formed on the exposed part of the gate electrode layer.

    Abstract: A multi-gate semiconductor device is formed including a semiconductor substrate. The multi-gate semiconductor device also includes a first transistor including a first fin portion extending above the semiconductor substrate. The first transistor has a first channel region formed therein. The first channel region includes a first channel region portion doped at a first concentration of a first dopant type and a second channel region portion doped at a second concentration of the first dopant type. The second concentration is higher than the first concentration. The first transistor further includes a first gate electrode layer formed over the first channel region. The first gate electrode layer may be of a second dopant type. The first dopant type may be N-type and the second dopant type may be P-type. The second channel region portion may be formed over the first channel region portion.
