摘要:
A method for fabricating a dual silicide device includes growing source and drain (S/D) regions for an N-type device, forming a protection layer over a gate structure and the S/D regions of the N-type device and growing S/D regions for a P-type device. A first dielectric layer is conformally deposited and portions removed to expose the S/D regions. Exposed S/D regions for the P-type device are silicided to form a liner. A second dielectric layer is conformally deposited. A dielectric fill is formed over the second dielectric layer. Contact holes are opened through the second dielectric layer to expose the liner for the P-type device and expose the protection layer for the N-type device. The S/D regions for the N-type device are exposed by opening the protection layer. Exposed S/D regions adjacent to the gate structure are silicided to form a liner for the N-type device. Contacts are formed.

A FinFET device includes a semiconductor fin, a gate electrode extending over a channel of the fin and sidewall spacers on each side of the gate electrode. A dielectric material is positioned on each side of a bottom portion of said fin, with an oxide material on each side of the fin overlying the dielectric material. A recessed region, formed in the fin on each side of the channel region, is delimited by the oxide material. A raised source region fills the recessed region and extends from the fin on a first side of the gate electrode to cover the oxide material to a height which is in contact with the sidewall spacer. A raised drain region fills the recessed region and extends from the fin on a second side of the gate electrode to cover the oxide material to a height which is in contact with the sidewall spacer.

A FinFET transistor includes a fin of semiconductor material with a transistor gate electrode extending over a channel region. Raised source and drain regions of first epitaxial growth material extending from the fin on either side of the transistor gate electrode. Source and drain contact openings extend through a pre-metallization dielectric material to reach the raised source and drain regions. Source and drain contact regions of second epitaxial growth material extend from the first epitaxial growth material at the bottom of the source and drain contact openings. A metal material fills the source and drain contact openings to form source and drain contacts, respectively, with the source and drain contact regions. The drain contact region may be offset from the transistor gate electrode by an offset distance sufficient to provide a laterally diffused metal oxide semiconductor (LDMOS) configuration within the raised source region of first epitaxial growth material.

Embodiments are directed to a method of fabricating a portion of a nanowire field effect transistor (FET). The method includes forming a sacrificial layer and a nanowire layer, removing a sidewall portion of the sacrificial layer and forming a diffusion block in a space that was occupied by the removed sidewall portion of the sacrificial layer. The method further includes forming a source region and a drain region such that the diffusion block is between the sacrificial layer and at least one of the source region and the drain region, and removing the sacrificial layer using a sacrificial layer removal process, wherein the diffusion block prevents the sacrificial layer removal process from also removing portions of at least one of the source region and the drain region.

Embodiments are directed to a method of forming a leakage current stopper of a fin-type field effect transistor (FinFET). The method includes forming at least one fin having an active region, a non-active region and a channel region in the active region.
