Dow Launches New Abrasive-Free Copper Bulk CMP Process

Taipei, Taiwan – September 12, 2011 – In conjunction with industry tradeshow SEMICON Taiwan, Dow Electronic Materials, a business unit of The Dow Chemical Company (NYSE:DOW), today introduced its latest Copper (Cu) bulk chemical mechanical planarization (CMP) process. The new offering combines Dow’s unique RL3100™ abrasive-free, self-stopping chemistry and VISIONPAD™ 5000 polishing pad to offer a high performance, low cost of ownership (COO) solution for Cu Bulk/Clear CMP. 

“As the industry strives to keep up with Moore’s Law by developing ever-smaller and more dense technology nodes, new approaches to CMP are needed to address significant manufacturing challenges,” said Dr. Wei-Chung Yu, CMP Slurry R&D Director of Dow Electronic Materials. “Our research scientists and application specialists collaborate directly with our customers to ensure that our CMP solutions are at the leading edge of technology as IC manufacturers look to migrate to the next technology node. Our new abrasive-free CMP process has evolved out of this effort and has already been met with strong interest due to the significant performance and cost benefits it offers.”

The key benefit of Dow’s RL3100™ + VISIONPAD™ 5000 polishing pad Cu CMP process is the ability to provide low dishing and no erosion that is independent of line width and array pattern density. When combined with high Cu rates, clearing capability and almost infinite selectivity to barrier and dielectric films, the results include higher yields, tight Rs control, high throughput, and wide process margin.  

The unique RL3100™ abrasive-free chemistry ensures minimal defectivity and higher yields by eliminating the erosion or scratching associated with standard abrasive-containing slurries. This novel approach delivers low COO due to the solution’s dilutability, elimination of pad cleaning requirements between processed wafers, and use of minimal pad conditioning to extend pad life.

Production-proven, Dow’s unique abrasive-free technology has been in use for 90–45 nm 300 mm high volume manufacturing for more than three years. It has also been selected as the process of record for the 14 nm node by a technology-leading IDM, and is the process of record for a leading foundry manufacturer for Cu CMP in a TSV process scheduled to ramp at the 28 nm node.
