Wrap around contact process margin improvement with early contact cut |
| abstract |
A method is presented for forming a wrap around contact. The method includes forming a p-type epitaxial region and an n-type epitaxial region over a substrate, forming a dielectric pillar between the p-type epitaxial region and the n-type epitaxial region, depositing sacrificial liners around both the p-type epitaxial region and the n-type epitaxial region, and depositing an inter-layer dielectric (ILD). The method further includes forming trenches in the ILD extending into the sacrificial liners, wherein the trenches are vertically aligned with the p-type epitaxial region and the n-type epitaxial region, removing the sacrificial liners to define irregular-shaped openings exposing the p-type epitaxial region and the n-type epitaxial region, and filling the irregular-shaped openings with a conductive material defining the wrap around contact. |
