Device isolation with improved thermal conductivity

Device isolation with improved thermal conductivity

A method of making a semiconductor structure includes forming a trench through a shallow trench isolation (STI) structure and into a substrate, and forming a liner including an electrical insulator material on sidewalls of the trench. The method also includes forming a core including a high thermal...

Zusammenfassung:A method of making a semiconductor structure includes forming a trench through a shallow trench isolation (STI) structure and into a substrate, and forming a liner including an electrical insulator material on sidewalls of the trench. The method also includes forming a core including a high thermal conductivity material in the trench and on the liner, and forming a cap in the trench and on the core.
