  • Precision Polymer Engineering (PPE) announces the launch of a highly fluorinated polymer –
    providing sealing for critical locations in aggressive etch and CVD plasma process tools

    Blackburn, UK (6/23/16) – Precision Polymer Engineering (PPE), one of the world’s leading manufacturers of high performance molded elastomer seals and O-rings, will launch Nanofluor® Y75G at SEMICON West in San Francisco this July. The highly fluorinated material can be regarded as a FKM/FFKM hybrid, and is available as O-rings and custom shapes, designed for use in critical applications.  Having undergone comprehensive internal testing using different plasma chemistries and plasma sources, data shows the new material performs better than its closest competitors and, in many cases, significantly better than traditional FFKM products.

    Within critical applications where the seal is in direct contact with the chemistry, such as chamber lid seals, the challenge is sourcing a seal that is of the highest purity, is plasma-resistant, and has low concentrations of nano-particle filler that is compounded to reduce particle agglomeration, yet is competitively priced. Sourcing an appropriate sealing material is critical to avoid wafer contamination which can reduce yield. In addition to this, it is also important to ensure seal lifetime compatibility with existing maintenance cycles and assess ways to potentially increase the process tool productive period, or uptime, leading to lower cost of consumables.

    Semiconductor production creates some of the most aggressive environments encountered by seals and original equipment manufacturers are continually making conscious efforts to source better sealing materials. PPE has developed a highly chemical-resistant, nano-filled elastomer seal; providing a unique and process-optimized sealing solution for many semiconductor process applications. The new material was tested against the market-leading materials, in several commonly used plasma chemistries, and also for O2 plasma-resistance. Depending on chemistry, mass loss was measured after a minimum of 12 hours’ continuous exposure. A 20-30% improvement in erosion rate using the new material, compared with a key competitor was observed, and, compared with similar filler system groups, its erosion rates were unsurpassed.

    This uniquely compounded material ensures low plasma erosion rates and increased seal lifetime, which, when coupled with low trace metal content, reduces the risk of lower yield and warranty failures. Additionally, the high fluorine content guarantees a generic high chemical resistance, whilst the use of low levels of nano-particle filler resulting in low filler particle agglomeration, means particle generation or large particle contamination are less likely.

    Commenting on the launch of the new material, Knut Beekmann, Market Manager for Semicon at PPE, said: “PPE is always striving to produce high-performance seals, capable of delivering solutions for critical  applications, to help address common challenges. The data we generated from extensive internal testing proves Nanofluor® Y75G is able to consistently outperform other material grades under the same conditions. We are confident that our customers will see significant improvements in performance, while achieving all-important cost savings.”

    PPE will be exhibiting at SEMICON West 2016, San Francisco from July 12-14th. Come and visit the team at Booth #1345 to see our new product and discuss how a sealing partnership can benefit your business.

  • Perlast
    The ultimate perfluoroelastomers for sealing applications where chemical resistance and high temperature performance are critical. Perlast delivers high temperature stability up to 327°C (620°F), and almost universal chemical resistance....

  • PPE manufactures and supplies the Perlast® range of high performance perfluoroelastomer materials (FFKM).

    Perfluoroelastomer (FFKM) is the most chemically resistant elastomer available and is effectively a rubber form of PTFE. Perlast® perfluoroelastomer grades provide other properties which prove most valuable in critical sealing applications where purity, high temperatures and retention of sealing force are paramount.

    The Perlast® range of perfluoroelastomer materials are at the leading edge of polymer technology. They have been developed to offer superior sealing solutions with enhanced performance and improved functionality, which is proven in the field (see case studies).

    Features of Perlast® FFKM seals include:

    • High temperature stability up to 327°C (620°F)
    • Almost universal chemical resistance
    • Outstanding mechanical properties
    • High purity materials
    • FDA, USP Class VI and 3A compliance
    • Highest quality parts

  • Kimura
    A unique range of fully organic elastomers for semiconductor sealing applications which demand extreme plasma resistance....

  • The Kimura® range of high performance elastomer materials utilize a controlled molecular architecture which provides a unique self-reinforcing polymer structure, elimiating the need for fillers of any kind.  This high purity material breaks new ground in elastomer technology, developed specifically for aggressive semiconductor applications. 

    Kimura® elastomers are NOT perfluoroelastomers or any other standard type of elastomer material.  They are a new breed of elastomer, specifically developed by PPE, for the semiconductor industry, to offer a step-change in sealing performance, surpassing what has previously been achievable.

    The high purity of the polymer combined with the absence of any fillers makes Kimura® materials suitable for processes involving lower feature sizes. Kimura® materials also provide low coefficient of thermal expansion, low compression set and extremely low etch rates in aggressive plasma environments.

    Key Attributes

    • Exceptionally pure - does not contain any fillers which may cause particulation problems.
    • Outstanding plasma resistance – ideal for Chlorine, Fluorine & Oxygen chemistries.
    • Exceptionally low plasma etch rate
    • Low thermal expansion
    • Retro-fits existing O-ring grooves (including FKM & FFKM grooves)
    • Low permeation
    • Low out-gassing
    • Low adhesion (reduced sticking)
    • Low friction, high strength and high modulus make Kimura materials ideal for constant force dynamic applications.
