Intel Investors - The First Glimpse of Intel's Copper Technology Intel and Applied Materials are jointly presenting a paper on Copper Metallization technology. techweb.com Here are some excerpts: "Intel has kept its work under the tightest wraps-and it may be broader-based than any other company's. A powerful hint comes from a paper Intel-and engineers from Applied Materials Inc.-was to deliver at last week's IEEE interconnect-technology conference. The paper focuses on research to determine whether a conventional, subtractive-etch process can lay down copper interconnects. For now, Damascene dominates, since it's the only way to create the necessary thick, barrel-shaped copper structures. Most experts don't put much stock in etch for copper interconnects. Torturously slow etch rates have been a big problem. Surprisingly, the Intel-Applied paper sees progress. "Copper-etch rates at greater than 5,000 [angstroms per minute] have been achieved, and post corrosion-free copper-etch performance has been demonstrated for times in excess of 72 hours," the paper's abstract notes."
