GATE STACK FORMED WITH INTERRUPTED DEPOSITION PROCESSES AND LASER ANNEALING |
摘要 |
Semiconductor structures and methods of fabricating the same using interrupted deposition processes and multiple laser anneals are provided. The structure includes a high-k gate stack with a high-k bilayer or nanolaminate where a bottom portion of the bilayer is crystallized while a top portion of the bilayer is amorphous. |
