    Abstract: In the manufacture of a FinFET device, an isolation architecture is provided between gate and source/drain contact locations. The isolation architecture may include a low-k spacer layer and a contact etch stop layer. An upper portion of the isolation architecture is removed and replaced with a high-k, etch-selective spacer layer adapted to resist degradation during an etch to open the source/drain contact locations. The high-k spacer layer, in conjunction with a self-aligned contact (SAC) capping layer disposed over the gate and overlapping a sidewall of the isolation layer, forms an improved isolation structure that inhibits short circuits or parasitic capacitance between the gate and source/drain contacts.
