Abstract:
Semiconductor devices having air gap spacers that are formed as part of BEOL or MOL layers of the semiconductor devices are provided, as well as methods for fabricating such air gap spacers. For example, a method comprises forming a first metallic structure and a second metallic structure on a substrate, wherein the first and second metallic structures are disposed adjacent to each other with insulating material disposed between the first and second metallic structures. The insulating material is etched to form a space between the first and second metallic structures. A layer of dielectric material is deposited over the first and second metallic structures using a pinch-off deposition process to form an air gap in the space between the first and second metallic structures, wherein a portion of the air gap extends above an upper surface of at least one of the first metallic structure and the second metallic structure.

Claim (Index 16):
The method of  claim 11 , wherein depositing a layer of dielectric material over the first and second metallic structures comprises:\n depositing a non-conformal layer of dielectric material to form a dielectric capping layer having a pinch-off region that is aligned to the space between the first and second metallic structures; wherein the pinch-off region is formed in the dielectric capping layer above the upper surface of the at least one first metallic structure and second metallic structure.
