Dow Electronic Materials, a business unit of The Dow Chemical Company (NYSE:DOW), today announced volume availability of KLEBOSOL® II 1730 colloidal silica slurry for use in the chemical mechanical planarization (CMP) process. KLEBOSOL® II 1730 slurry has demonstrated a 50 percent improvement in defects when used for inter-layer dielectrics (ILD) and can increase removal rates by up to 10 percent when compared to previous generations of KLEBOSOL® II 1630. Ideal for ILD and post-metal buff applications, the new slurry increases tool uptime, reduces consumable costs and improves throughput for critical CMP process steps.

“Semiconductor manufacturers are continually looking to improve cost of ownership (COO) and performance to maintain the pace of Moore’s Law,” said Mario Stanghellini, Global Marketing Director for Dow Semiconductor Technologies. “Dow is committed to bringing deep materials science and nano-particle expertise that enables the development of advanced slurry products to meet next-generation process targets for CMP.”

KLEBOSOL® II 1730 slurry features a unique new elongated abrasive particle morphology that improves slurry utilization since it is dilutable with lower point-of-use (POU) solids, making it highly cost-effective. It offers comparable planarization efficiency to fumed silica slurries and high removal rates that increase throughput to reduce overall cost of ownership, especially when combined with Dow’s process control capabilities. Additional savings can be achieved when combined with the long pad-life of Dow’s CMP pads, which can be further extended through the need for much less aggressive conditioning. KLEBOSOL® II 1730 is easy to handle, with no agglomeration and accepts 0.3 μm POU filtration capability to further minimize defectivity.
