copper chip |
Also found in: Wikipedia | 0.04 sec. |
copper chipA chip that uses copper rather than aluminum in the top metalization layers, which interconnect all transistors and components together. Copper provides better performance, because it has less resistance than aluminum. Resistance increases as the lines (tracks) get smaller. In order to accommodate ever-decreasing die sizes, materials with inherent less resistance are required. Copper might have been used earlier, but it diffused into the silicon until IBM discovered a way to prevent that from happening. IBM delivered the first copper-based microprocessors in 1998.

Microprocessors, the chips that process information, are headed for another boost in performance with the arrival of copper-based chips. The Endura 300mm system supports the industry's widest array of metallization applications, including barrier/seed layers for copper-based chips, conductor and barrier films for aluminum-based devices, transistor and contact-level metals and barriers, and packaging applications such as under bump metallization and bondpads. The state-of-the-art facility, equipped with a full complement of process, yield enhancement and automation technologies, can greatly speed customers' development and introduction of future faster, more powerful, sub-100-nanometer copper-based chips. |
