Abstract:
The present disclosure provides a method of fabricating an integrated circuit in accordance with some embodiments. The method includes forming a source and a drain on a fin active region of a semiconductor substrate; depositing an interlayer dielectric (ILD) layer on the source and drain; patterning the ILD layer to form a first contact hole and a second contact hole aligning with the source and drain, respectively; forming a dielectric material layer in the first contact hole; and forming a first conductive feature and a second conductive feature in the first and second contact holes, respectively.

Claim (Index 10):
A method of fabricating an integrated circuit, comprising:\n forming a source and a drain on a fin active region of a semiconductor substrate; depositing an interlayer dielectric (ILD) layer on the source and drain; patterning the ILD layer to form a first contact hole and a second contact hole aligning with the source and drain, respectively; forming a dielectric material layer in the first contact hole; forming a dielectric feature in the first contact hole, wherein the dielectric feature has a bottom surface directly contacting the source and sidewalls directly contacting the first dielectric material layer; and forming a first conductive feature and a second conductive feature in the first and second contact holes, respectively, wherein the forming of the dielectric material layer in the first contact hole includes depositing the dielectric material layer in the first contact hole; and performing an anisotropic etching process to remove a bottom portion of the dielectric material layer within the first contact hole such that the source is exposed.
