Semiconductor Flow Control Solutions

Precision Piping. Trusted Solutions.

High-purity flow control solutions backed by technical expertise and dependable supply chain support.

Harrington Process Solutions supports semiconductor fabs with high-purity semiconductor piping solutions for chemical delivery, ultra-pure water, utilities, and waste management. Our systems are engineered to maintain process integrity, minimize contamination risk, and support consistent, reliable operation in advanced manufacturing environments.

Plastic process flow control is critical wherever ultra-high purity and chemical compatibility are required, safeguarding sensitive processes while holding stable performance in tightly controlled fabrication environments.

Delivered Outcomes

UPW AND CHEMICAL DISTRIBUTION

Ultra-pure water and aggressive process chemicals demand different materials in the same fab. We match PVDF, PFA, and PP to each loop and fusion-join every connection to protect purity from the header to the tool.

PROCESS WASTE AND DRAIN SYSTEMS

Spent acids, solvents, and slurries need chemical-rated drainage, not standard DWV pipe. We supply corrosion-resistant and double-contained waste systems that handle the chemistry and contain a leak before it spreads.

WET BENCH AND TOOL SUPPORT

Tool hookups are where purity, pressure, and tight timelines meet. We deliver the high-purity valves, fittings, tubing, and fabricated assemblies that connect wet benches and process tools cleanly and on schedule.

Yield Protection Starts In The Fluid Path

Semiconductor piping is held to a standard no other industry requires. Particle shedding, ionic contamination, and extractables leaching from pipe walls all reach the wafer, and at advanced nodes the tolerance for any of them approaches zero. A single mis-specified material, a dead leg that traps stagnant fluid, or a joint that was threaded instead of fused can raise defect counts and cost a fab far more than the piping ever did. The fluid path is not plumbing. It is yield protection, and specifying the right high purity pipe the first time is the difference between predictable output and an unexplained yield excursion.

One Source For Every Fluid System In The Facility

A semiconductor fabrication facility does not run on one fluid system. It runs on ultra-pure water, UHP chemical and slurry, bulk and specialty gas, process cooling water, wastewater treatment, exhaust, and the cleanroom itself, each with its own purity class and material requirements. Harrington supplies all of them. That single-source breadth means one technical relationship instead of a dozen vendors to reconcile, and it matters most during a fab buildout, where compressed schedules and multiple contractors leave no room for a supply gap. With national inventory positioned near major fab regions and engineers who specify these systems for a living, Harrington keeps high-specification projects moving without sacrificing the purity standards the process demands

Customer Success Story - Supporting a Multi-Phase Semiconductor Expansion

Harrington partnered with a leading semiconductor manufacturer to support a multi-phase facility expansion involving complex tool installations and high-purity system requirements.With multiple contractors operating simultaneously and timelines tightly managed, the project required consistent material availability, responsive support, strong coordination across teams, and the ability to adapt quickly in a fast-paced, high-specification environment.

High-Purity Materials And Joining, Matched To Each System

The right UHP piping for a semiconductor fab is selected system by system, not by defaulting to one material. PVDF is the workhorse for ultra-pure water distribution and many acid loops, valued for chemical resistance and clean extractable performance, and Harrington fabricates and supplies PVDF pipe systems built for these duties. PFA carries the lowest extractables for the most critical chemical contact, including aggressive bulk chemistries. Polypropylene is the cost-effective choice for drains and less-critical waste. For specialty and bulk gases, electropolished 316L tubing is joined by orbital welding. Across every wetted thermoplastic system, fusion joining replaces threads and solvent cement to eliminate the crevices and leak paths that become contamination sources. Extractables and leachables are specified to SEMI F57 and the applicable ASTM standards, while system design controls dead legs, flow velocity, and surface finish to hold particle counts down. The product systems below apply that logic across the fab.
