ABSTRACT:
A trench (70) is formed in a dielectric layer (20). A first metal layer (80) is formed in the trench using physical vapor deposition. A second metal layer (100) is formed in the trench (70) over the first metal layer (80) using chemical vapor deposition. Copper (110) is used to fill the trench (70) by electroplating copper directly onto the second metal (100).
