Suggested Kalrez® Materials for Semiconductor Applications


DuPont™ Kalrez® 6375UP
is a general purpose black product for all wet process applications. This product exhibits excellent chemical resistance to all different types of wet process chemicals including acids, bases and amine-base strippers. It features low elemental extractables with good mechanical and compression set properties and is well-suited for both static and dynamic wet process seal applications (e.g., filter seals, drain seals and flow meters). A maximum application temperature of 275 °C is suggested. Ultrapure post-cleaning and packaging is standard for Kalrez® 6375UP parts.

DuPont™ Kalrez® 8475 is a white product which reduces IR absorption and reduces seal temperature, and is well suited for RTA and RTP applications. Ultrapure post-cleaning and packaging is standard.

DuPont™ Kalrez® 8900 is a black product for all thermal processes, e.g., oxidation, diffusion furnace, metal CVD, ALD and LPCVD. It offers outstanding thermal stability, very low outgassing and excellent (low) compression set properties. Kalrez® 8900 exhibits excellent retention of physical properties at elevated temperatures, has excellent mechanical strength and is well-suited for both static and dynamic sealing applications. A maximum application temperature of 325°C is suggested. Short excursions to higher temperatures may also be possible. Ultrapure post-cleaning and packaging is standard for all Kalrez® 8900 parts.

DuPont™ Kalrez® 9100 is an amber translucent product targeted specifically for HDPCVD and PECVD processes. It has also exhibited excellent performance in “select” etch process 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 is suggested. Ultrapure post-cleaning and packaging is standard for all Kalrez® 9100 parts.

DuPont™ Kalrez® 9300 is a brown product for Dielectric (Oxide) Etch processes. It has been specifically designed for use in applications where the plasma environment is a combination of ions (“physical”) and radicals (“chemical”), i.e., where a balance of “physical” and “chemical” plasma erosion resistance is typically required. Kalrez® 9300 exhibits excellent resistance to oxygen and fluorine-based plasma and etch process chemistry. It also offers very low metals content, excellent thermal stability and mechanical strength and is well suited for both static and dynamic sealing applications. A maximum application temperature of 300°C is suggested. Ultrapure post-cleaning and packaging is standard for all Kalrez® 9300 parts.

DuPont™ Kalrez® 9500 is a tan product for Deposition, Ash/Strip and Conductor (Poly/Metal) Etch processes. It has been specifically designed for use in applications where ozone is used for processing, e.g. SACVD, PECVD ultra-low K (BLOK™) and where the plasma environment is more “chemical,” i.e., where oxygen and fluorine radicals are more dominant. Kalrez® 9500 exhibits excellent resistance to CVD and ash/strip process chemistry, i.e., ozone, ammonia and water vapor. It also offers outstanding thermal stability, very low outgassing and excellent mechanical strength and is well suited for both static and dynamic sealing applications. A maximum application temperature of 310°C is suggested. Kalrez® 9500 can also withstand short term excursions up to 325°C. Ultrapure post-cleaning and packaging is standard for all Kalrez® 9500 parts.

Kalrez® 8085 exhibits very low particle generation and low weight loss in oxygen and fluorine-based plasma, has excellent mechanical strength and is well-suited for both static and dynamic sealing applications (e.g., bonded slit valve doors, bonded gate valves, bonded pendulum valves, gas orifice seals, gas feed-through seals, chamber lid seals). A maximum application temperature of 240 °C is suggested. Kalrez® 8085 can also withstand short-term excursions to 275 °C. Ultrapure post-cleaning and packaging is standard for all Kalrez® 8085 parts.

DuPont™ Kalrez® 8575 perfluoroelastomer parts are a white product for select etch, ash/strip and deposition process applications, and are also an excellent choice for exhaust line (sub-fab) seals.

DuPont™ Kalrez® 1050LF is a black product targeted specifically for semiconductor wet process applications where high concentrations of certain amines are present. It exhibits excellent amine resistance and has excellent thermal stability and mechanical strength properties. Kalrez® 1050LF is not recommended for use in organic or inorganic acids at elevated temperatures. A maximum application temperature of 288 °C is suggested. Ultrapure post-cleaning and packaging is available. Please order this product as 1050UP when specifying ultrapure post-cleaning and packaging. **NOTE: 1050LF is approaching end-of-life.

DuPont™ Kalrez® Spectrum™ 0040 perfluoroelastomer parts are specifically designed for low-temperature environments where significant chemical resistance is required (-42°C).

Other DuPont™ Product Information

DuPont™ Kalrez® Bonded Door Seals are used for gate valves and slit valve door seal applications. They provide improved sealing performance versus conventional o-rings by reducing particle generation, extending seal life and minimizing replacement time during preventive maintenance. Bonded doors are offered in most Kalrez® materials.

DuPont™ Tri-Lobe Seals DuPont has developed a seal design to improve seal life in dovetail grooves.
