Cabot Microelectronics leveraged its technological expertise and experience in the semiconductor industry in developing highly engineered slurries to meet the evolving process challenges facing the disk drive industry. Cabot Microelectronics' unique chemical slurry formulations play a critical role in providing a new level of performance and cost benefit to manufacturers of rigid disks and magnetic heads, two critical components of the disk drive. All Cabot Microelectronics' slurries are designed for high removal rates, outstanding surface finish, proper selectivity for maximum planarization, cleanability and decreased defectivity.

Rigid Disk Substrates
Achieving near-perfect planarity on the surface of the rigid disk substrate--an integral part of a computer's disk drive--is related directly to the ability to increase data storage (information) capacity on the disk drive. The advent of memory-intensive computer operating systems and multi-media application software is driving this demand. CMP enables disk drive manufacturers to cost-effectively produce high-performance disk drives.

Slurries
Developed in direct response to customer demand for improved surface quality, Cabot Microelectronics offers a second-step, "ultra super polishing" slurry for media substrates that produces a superior surface finish. The result is higher performing disk drives and increased data storage capacity.

Magnetic Heads
Cabot Microelectronics' complete solution set for gigantic magneto-resistive (GMR) CMP includes slurries for such applications as:

• Nickel iron
• Aluminum oxide
