    Abstract: In one embodiment a method is provided that includes providing a structure including a semiconductor substrate (12) having at least one device region (14) located therein, and a doped semiconductor layer located on an upper surface of the semiconductor substrate in the at least one device region. After providing the structure, a sacrificial gate region (28) having a spacer (34) located on sidewalls thereof is formed on an upper surface of the doped semiconductor layer. A planarizing dielectric material (36) is then formed and the sacrificial gate region (28) is removed to form an opening (38) that exposes a portion of the doped semiconductor layer. The opening is extended to an upper surface of the semiconductor substrate (20) and then an anneal is performed that causes outdiffusion of dopant from remaining portions of the doped semiconductor layer forming a source region (40) and a drain region (42) in portions of the semiconductor substrate that are located beneath the remaining portions of the doped semiconductor layer. A high k gate dielectric (46) and a metal gate (48) are then formed into the extended opening.

    Abstract: A FinFET structure is formed by forming a hardmask layer on a substrate including a silicon-containing layer on an insulating layer. The hardmask layer includes first, second and third layers on the silicon-containing layer. An array of fins is formed from the hardmask layer and the silicon-containing layer. A gate is formed covering a portion but not all of a length of each of the array of fins. The portion covers each of the fins in the array. The gate defines source/drain regions on either side of the gate. A spacer is formed on each side of the gate, the forming of the spacer performed to remove the third layer from portions of the fins in the source/drain regions. The second layer of the hardmask layer is removed from the portions of the fins in the source/drain regions, and the fins in the source/drain regions are merged.

    Abstract: A method is provided for fabricating a finFET device. Fin structures are formed over a BOX layer. The fin structures include a semiconductor layer and extend in a first direction. A gate stack is formed on the BOX layer over the fin structures and extending in a second direction. The gate stack includes a high-K dielectric layer and a metal gate. Gate spacers are formed on sidewalls of the gate stack, and an epi layer is deposited to merge the fin structures. Ions are implanted to form source and drain regions, and dummy spacers are formed on sidewalls of the gate spacers. The dummy spacers are used as a mask to recess or completely remove an exposed portion of the epi layer. Silicidation forms silicide regions that abut the source and drain regions and each include a vertical portion located on the vertical sidewall of the source or drain region.

    Abstract: A transistor, such as a FinFET, includes a gate structure 6, 102 disposed over a substrate. The gate structure has a width and also a length and a height defining two opposing sidewalls of the gate structure. The transistor further includes at least one electrically conductive channel between a source region and a drain region that passes through the sidewalls of the gate structure; a dielectric layer 310 disposed over the gate structure and portions of the electrically conductive channel that are external to the gate structure; and an air gap 314 underlying the dielectric layer. The air gap is disposed adjacent to the sidewalls of the gate structure and functions to reduce parasitic capacitance of the transistor. At least one method to fabricate the transistor is also disclosed.
