Abstract
Capacitor strap connections for a memory cell and device structures for making such capacitor strap connections. A deep trench capacitor is formed in a substrate. A collar comprised of an electrical insulator is formed at least partially inside an upper section of a deep trench in which the deep trench capacitor is formed. A portion of the collar is removed to define a notch extending through the collar, and a connection strap is formed in the notch. A fin is formed from a portion of the substrate, and is coupled by the connection strap with an electrode of the deep trench capacitor that is located inside the deep trench.
