FKM and FFKM Seals for Semiconductor Manufacturing
Cross-contamination tolerance in semiconductor process is near-zero. Our single dedicated A-mixing line — with sequence-ordered scheduling and validated cleaning SOP — delivers the compound purity that wafer-fab seals demand.
Where We Engage
We engage on semiconductor sealing as a co-development service, not as an off-shelf catalog. Two engagement modes:
FKM-Based Process Seals (proven)
Wafer handling, chamber static seals, gas-line gaskets in non-aggressive plasma environments. Built on 30 years of FKM compound development. Standard 8-16 week lead time.
FFKM-Based Process Seals (co-development)
Aggressive plasma etch, ALD/CVD chamber dynamic seals, high-purity gas delivery. FFKM is our flagship co-development offering — premium chemistry, premium pricing, premium reliability. Engagement: structured 5-stage development with our Japanese formulation team, NDA-backed.
Why Single-Line Matters in Semicon
In a multi-line plant, yesterday's high-carbon-black batch can leave residue affecting today's FFKM batch — even with cleaning. We eliminate that risk by design: ONE A-line, sequence-ordered (high-purity first, high-filler last), validated SOP between batches. Auditable.
Process Compatibility (Customer-Specified)
We do not publish standard FFKM formulations — every semiconductor application has unique process chemistry (etchant gases, RF power, thermal cycling). Submit your process conditions; we'll propose compound chemistry within 2-3 weeks under NDA.
