Abstract
The invention provides a method for electrically connecting a trench capacitor and a diffusion region, and also for electrically connecting a trench capacitor or a diffusion region with external circuitry in a semiconductor device. The method provides for formation of a strap or bridge contact by formation of strap holes exposing the electrical elements utilizing an oxide insulation layer and a nitride etch stop and a highly selective oxide:nitride etch and a selective nitride:oxide etch. The strap holes may then be filled with an electrical conductor.
