Abstract

A method including introducing a dielectric layer over a substrate between an interconnection line and the substrate, the dielectric layer comprising a plurality of alternating material layers; and patterning an interconnection to the substrate. An apparatus comprising a substrate comprising a plurality of devices formed thereon; and an interlayer dielectric layer comprising a base layer and a cap layer, the cap layer comprising a plurality of alternating material layers overlying the substrate.

Claims

exact text as granted — not AI-modified
1 . An apparatus comprising: 
 a substrate comprising a plurality of devices formed thereon; and    an interlayer dielectric layer comprising a base layer and a cap layer, the cap layer comprising a plurality of alternating material layers overlying the substrate.    
   
   
       2 . The apparatus of  claim 1 , wherein the cap layer comprises silicon dioxide as the ultimate material layer.  
   
   
       3 . The apparatus of  claim 1 , wherein the cap layer comprises a plurality of silicon dioxide layers alternated with at least one other material layers.  
   
   
       4 . The apparatus of  claim 3 , wherein the number of alternating silicon dioxide layers comprises at least six.
