Description

For PECVD/ALD/HDPCVD & Conductor Etch Applications

Product Description

DuPont™ Kalrez® 9100 is an amber translucent product targeted specifically for PECVD, ALD, HDPCVD and Conductor (Poly/Metal) Etch applications. Kalrez® 9100 has been specifically designed for low erosion and ultra-low particle generation in harsh plasma environments. It offers excellent thermal stability, very low outgassing as well as excellent elastic recovery and good mechanical strength properties and is well suited for both static and “select” dynamic sealing applications. A maximum application temperature of 300°C (572°F) issuggested. Ultrapure post-cleaning and packaging is standard for all Kalrez® 9100 parts.

Particle Generation

Conventional perfluoroelastomer (FFKM) sealing materials normally contain carbon black and/ormineral fillers. Newer products are either unfilled or formulated with polymeric fillers. Plasma resistance can be significantly different depending on the type of filler used. If the filler has high resistance to plasma, such as BaSO4, TiO2, etc., it can “shield” the polymer to reduce erosion or weight loss, but have the high potential for particle generation by leaving discrete particles behind once the polymer has become etched. Unfilled and polymeric filled products essentially contain no other elements other than carbon, fluorine and oxygen, which can be completely etched to form volatiles, thereby significantly reducing the potential for contamination. Figure 1 shows the relative particle generation of DuPont™ Kalrez® 9100 versus a nano-silica and a metallic oxide filled FFKM product in differentplasmas.

Fabs Choose Kalrez® 9100 For ImprovedPerformance

Kalrez® 9100 has been reported to significantly improve wafer production in a variety of semiconductor process applications where oxygen and fluorinated plasmas are used during the cleaning cycle. In a number of evaluations at fabline customers, Kalrez® 9100 exhibited less erosion, lower particle generation and longer seal life compared to competitive perfluoroelastomers in both static and dynamic sealing applications.
