Assignee: TEXAS INSTRUMENTS INCORPORATED
Field: Semiconductors (Electrical engineering)
Classification: CPC H  C | IPC H

Claim 0:
1. A method of forming an integrated circuit, comprising:
electroplating a first metal layer over a semiconductor substrate;
performing a first rinse process that rinses the first metal layer with water;
performing a first drying process that dries the first metal layer after the first rinse process;
electroplating a second metal layer on the first metal layer without annealing the first metal layer;
performing a second rinse process that rinses the second metal layer with water;
performing a second drying process that dries the second metal layer after the second rinse process;
annealing the first and second metal layers after the second drying process, thereby forming a final metal layer; and
forming interconnections from the final metal layer, the interconnections electrically connecting electronic components formed in or over the semiconductor substrate.
