Word line hook up with protected air gap
A method of forming a semiconductor device includes forming a plurality of word lines separated by air gaps with contact pad structures connected to the word lines, and forming a dummy structure directly opposite an air gap between neighboring word lines. Subsequently, the contact pad structures are...

| Zusammenfassung: | A method of forming a semiconductor device includes forming a plurality of word lines separated by air gaps with contact pad structures connected to the word lines, and forming a dummy structure directly opposite an air gap between neighboring word lines. Subsequently, the contact pad structures are cut into individual contact pads by a contact pad cut that intersects the dummy structure. |
