Abstract:
A semiconductor device and method of manufacture are provided. In an embodiment a first contact is formed to a source/drain region and a dielectric layer is formed over the first contact. An opening is formed to expose the first contact, and the opening is lined with a dielectric material. A second contact is formed in electrical contact with the first contact through the dielectric material.

Claim (Index 9):
A method comprising:\n forming a fin extending from a substrate; forming a gate stack on the fin; forming a source/drain region adjacent to the gate stack; forming a first contact to the source/drain region; depositing a dielectric layer having a first portion over the first contact and a second portion over the gate stack; forming an opening through the first portion of the dielectric layer; depositing a dielectric liner along sidewalls and a bottom of the opening; removing a portion of the dielectric liner along the bottom of the opening to expose the first contact, the gate stack remaining covered by the second portion of the dielectric layer after removing the portion of the dielectric liner; and filling the opening with a conductive material to form a second contact to the first contact.
