Why purity decides yield

A metal ion on a wafer is a defect.

≤ 1 ppb

Mobile ions

Sodium and potassium migrate through gate oxide and shift threshold voltage — so Na and K are held to ≤ 1 ppb.

≤ 0.5 ppb

Transition metals

Copper and nickel form recombination centres and cut carrier lifetime.

≤ 100/mL

Particles > 0.5 µm

Released limit for Ultrapure PPB; ≤ 25 per mL for PPT grades.

⚠ Strong oxidiser. Keep away from organic material; specialised storage and disposal required.

Handling and storage

Store in a dedicated, well-ventilated area away from organic material, reducing agents and dehydrating agents. Keep on a spill tray of inert, non-combustible material. Hot or concentrated perchloric acid forms explosive mixtures with organic material. Digestions must be carried out only in a dedicated perchloric acid fume hood with a wash-down facility. Never evaporate to dryness.

Classification

DANGER — H271 May cause fire or explosion; strong oxidiser. H290 May be corrosive to metals. H314 Causes severe skin burns and eye damage.

One accountable party

A deviation is answered by the people who made the material, not passed on to a toller.

No third-party pack risk

HDPE containers are made by group company Pristius Pack, and ultrapure packing stays inside a trace-metal clean room under ULPA filtration.

Quality & compliance

Certified manufacture. Documented lots.

ISO 9001, 14001 and 45001 certified manufacture, ICP-MS release testing and a document pack for every market we ship into.

Quality & compliance

Water-based phasefluid chemistry from IFX Technologies GmbH replaces NMP, acetone and DMSO/TMAH in stripping and lift-off — supplied by Highpuris across North America and APAC.

Sustainability · IFX Technologies × Highpuris

Cleaner. Faster. Greener. The layer is lifted, not dissolved.

Phasefluid® from IFX Technologies GmbH (Leipzig) is a patented, water-based microemulsion that replaces acetone, NMP and DMSO/TMAH in photoresist stripping, metal lift-off and adhesive removal. Highpuris is its authorised distribution arm for North America; group company TresPure is its manufacturing arm for the APAC region.

The chemistry you take off the floor

Water-based (> 20% water), pH neutral, readily biodegradable and not flammable, with a single CLP pictogram. Removing NMP removes a REACH-restricted reproductive toxicant and its exposure monitoring; removing acetone removes flammables handling.

Qualified with resists from AZ, Fujifilm, JSR Micro, TOK, Shin-Etsu MicroSi, DuPont and others, and independently assessed by imec against a TMAH-based process.

Cost study at a semiconductor wafer manufacturer: €1,259,232 old process vs €409,614 with phasefluid. Individual results vary by process.

Green energy in our plants

Green energy in our plants, green chemistry in our customers'.

500 kW

Solar plant commissioned in 2025

Commissioned end-to-end at the group's Vadodara operation, moving manufacturing onto renewable power and reducing the embodied carbon of everything we ship.

Certified environmental management

ISO 14001:2015 for environmental management and ISO 45001:2018 for occupational health and safety, both UKAS-accredited. EcoVadis documentation has been submitted, targeting a Silver medal rating.

What it means for you

  • Lower embodied carbon. Renewable-powered manufacturing reduces the Scope 3 footprint of everything we ship.
  • Safer process chemistry. The IFX Technologies range removes NMP, acetone and DMSO from the wet bench.
  • ESG reporting support. ISO 14001 data and an EcoVadis scorecard to feed your own disclosures.
  • A long-term supplier. Investment on site is investment in continuity of supply.

About Highpuris

A supply arm with a plant behind it.

Highpuris builds resilient supply chains for critical high-purity materials, delivering to semiconductor fabs and laboratories across North America and Europe. What we sell is manufactured by our own group in Gujarat, India — which is how a US and UK operation can guarantee parts per billion.

Why that matters

Buyers of ppb-grade chemistry are right to be wary of pure traders.

A specification query, a deviation or a complaint is answered by the group that made the material — not passed down a chain to a toller we do not control. Common ownership and a common quality system give you one point of accountability, whichever group company invoices you.

One point of accountabilityA specification query is answered by the group that made it — not passed to a toller.
No third-party pack riskContainer quality and lead time are ours, which is why ultrapure packing holds a trace-metal clean room.
Traceable end to endThe batch record runs from vendor approval to the certificate that ships with the drum.

The domestic market

TresPure sells into India's pharmaceutical, photovoltaic, semiconductor and analytical industries in its own right — and is the manufacturing arm for IFX Technologies across the APAC region. India is not just where we manufacture; it is a market we serve directly, on the same specifications we export.

What it means for an export customer

  • Cost base without the compromise. Indian manufacturing economics, European certification discipline.
  • Scale already built. 22,200 m² across two plants — not capacity we plan to add.
  • Continuity of supply. A plant running the same grades for four decades does not disappear mid-qualification.

Capabilities

One supplier for the whole wet bench.

  • Document downloads: to download specification sheets and certificates of analysis we ask for your work e-mail (name and company optional) and send a one-time confirmation link. We record the confirmed address, the documents downloaded and the time, so that we can tell you if a document is revised and understand which products interest our customers.
