Abstract: An integrated circuit device and method for manufacturing the integrated circuit device is disclosed. The disclosed method provides improved control over a surface proximity and tip depth of integrated circuit devices. An exemplary integrated circuit device achieved by the method has a surface proximity of about 1 nm to about 3 nm and a tip depth of about 5 nm to about 10 nm. The integrated circuit device having such surface proximity and tip depth includes an epi source feature and an epi drain feature defined by a first facet and a second facet of a substrate in a first direction, such as a {111} crystallographic plane of the substrate, and a third facet of the substrate in a second direction, such as a { 100} crystallographic plane of the substrate.

Abstract: A method is described which includes providing a substrate and forming a first spacer material layer abutting a gate structure on the substrate. A second spacer material layer is formed adjacent and abutting the gate structure and overlying the first spacer material layer. The first spacer material layer and the second spacer material layer are then etched concurrently to form first and second spacers, respectively. An epitaxy region is formed (e.g., grown) on the substrate which includes an interface with each of the first and second spacers. The second spacer may be subsequently removed and the first spacer remain on the device decreases the aspect ratio for an ILD gap fill. An example composition of the first spacer is SiCN.

Abstract: An integrated circuit device and method for manufacturing the integrated circuit device is disclosed. The disclosed method provides improved control over a surface proximity and tip depth of integrated circuit device. In an embodiment, the method achieves improved control by forming a lightly doped source and drain (LDD) region that acts as an etch stop. The LDD region may act as an etch stop during an etching process implemented to form a recess in the substrate that defines a source and drain region of the device.

Abstract: A method for forming a high performance strained source-drain structure includes forming a gate structure on a substrate and forming a pocket implant region proximate to the gate structure. Spacers are formed adjacent to the gate structure. A dry etch forms a recess with a first contour; a wet etch enlarge the recess to a second contour; and a thermal etch enlarges the recess to a third contour. The source-drain structure is then formed in the recess having the third contour.
