Semiconductor Solar and LCD Manufacturing

Semiconductor production environments can represent some of the harshest environments that O-ring seals can encounter, processes can be very diverse from High heat, aggressive plasma, hot wet chemicals and Amines, and remote NF3 cleans, through the years different elastomeric materials have been developed to successfully handle such conditions like Kalrez ®, Chemraz ®, Perlast ® and others, Marco has developed its own brand name Markez ® Perfluoroelastomer materials that are equivalent but offer a cost advantage to others. An easy to use table is shown below.

In addition to Markez Perfluoroelastomers, Marco Rubber hold extensive inventory in Viton ® FKM, Fluorosilicone, Viton ® Extreme and more, Marco also offers a range of large vulcanized O-rings, we understand that sizes of process chambers have gotten bigger for Solar, LCD and Semiconductor manufacturing, we can offer O-rings that are several feet in diameter if needed using a range of different materials.

Typical Product:

  • O-rings
  • X-rings
  • VAT bonded gates
  • KF fittings and accessories
  • PTFE Throttle valves
  • Wafer pad seals
  • PTFE seals and O-rings
  • SES spring energized seals
  • Giant size O-rings

Common Material Offered:

  • Markez® Perfluoroelastomers and
    Perlast® (Kalrez®, Chemraz® and Valqua® Equivalents)
  • Brown, black and white FKM (Viton®)
  • High Temperature Red silicone
  • EPDM in different colors
  • Polyurethane for belts
  • Blue Fluorosilicone for Ash and some etch application.
  • Vespel®, PEEK®, PTFE, Delrin® and more.

Equipment:

Through years of experience we have developed a database and knowledge of most equipment in the Market, we can cross reference most OEM part number, Examples, Applied Materials Producer®, DPS, Emax®, HDP Ultima®, RTP, Centura®, P-5000, Lam Excellan®, TCP9600, 9400 Metal, Novellus Vector®, Altus®, Speed®, Sequel®, Tokyo Electron..etc. In addition to that we have worked with OEM manufacturer to develop new sealing methods to solve existing problems or for new designs.

Products:

Marco offers any O-ring size with no tooling charges, we also offer X-rings also called Quad-Ring® Seals for dynamic applications in any material, and many of the popular semiconductor O-ring sizes are already tooled. We offer VAT bonded gates in Perlast® and some Markez® materials, we also offer some of the 200mm and 300 mm bonded slit valves in a replacement materials to Chemraz® and Kalrez®. There are many Shamban® and other spring energized seal products in the market that we could directly replace at half the price! Those are used on robot spindles, throttle valves and other locations.

The temperature ranges presented above are approximations for dry air service only and should not be used to determine design specifications or end-use temperature limits. Actual temperature range of a compound in an end-use application is highly dependent on part type, hardware configuration, applied forces, chemical media, pressure and thermal cycling effects, and other factors. The most practical way of determining an end-use temperature range is testing in the actual application conditions. Consult a Marco Engineer for more details.


High Performance Valves

Our valves will change the way you design and operate your equipment.  Our on/off and flow control valves provide an elastomer free, all metal actuator for an increased temperature range. Since our valves can be custom made, the application possibilities are endless. New Semiconductor Processing concepts can be developed due to the ability of the valve and actuator to hold very tight vacuum, can operate in the heat zone, and many other possible uses.
