From the smartphones in our pockets to the satellites orbiting Earth, semiconductors power nearly every piece of technology we depend on. These chips are not just fundamental to modern life, they’re actively reshaping how we live, work, and connect.
The growing interest in AI processing, cloud computing, electric vehicles, and consumer electronics is transforming the semiconducting industry.
To keep pace, an estimated $1 trillion dollars is expected to be invested in new fabrication plants (fabs) by 2030. [1]
Growth relies on equipment and components that meet strict cleanliness standards. Even microscopic impurities can impact performance and yield in ultra-clean environments. Many of the gases used to make chips are also highly corrosive and toxic, requiring precise control to ensure both process safety and system integrity.
Why Use Metal Hose in Semiconductor Manufacturing
Metal hoses provide a clean, leak-tight solution for piping applications in semiconductor manufacturing. Impermeable by nature, and easily cleaned to meet customer specifications, they are ideal for transferring the ultrapure gases used across chipmaking processes.
Many of those gases are corrosive and will attack hose materials over time. With their signature corrosion resistant properties, metal hoses better resist degradation and offer longer service life than the alternatives in many applications. In “always on” fabs where uptime is critical, reducing the need for replacements is a significant advantage.
Capable of operating in high-temperature applications, stainless steel flex hoses are also used for heat removal, particularly within etching cabinets, where excess heat generated must be efficiently dissipated to protect sensitive components and maintain consistent process temperatures.
Why is Metal Superior to Other Materials Used in Semiconductor Manufacturing?
Teflon (PTFE) hoses are commonly found in semiconductor fabs, but many manufacturers are shifting away from them due to concerns around forever chemicals, known as per- and polyfluoroalkyl substances (PFAS).
Beyond these concerns, PTFE and rubber hoses are inherently porous, allowing a slow and steady release of gas into the environment. Many of these gases are toxic, flammable, and corrosive. Offgassing poses health and safety risks to employees working in the fab. Condensation of gases on sensitive equipment or surfaces risks equipment damage and product quality. Beyond these concerns, the costs associated with lost process gases is another consideration.
Rubber hoses also have a tendency to flake and chip, shedding debris inside the hose that can contaminate critical chemical compounds and impair delicate semiconductor operations.
By contrast, metal hoses are recyclable and completely non-porous, eliminating environmental concerns and worries over the effects of offgassing. Combined with their superior corrosion resistance and durability, they are the ideal choice for many semiconductor manufacturing applications.
How Penflex Supports Semiconductor Applications
At Penflex, we understand the demanding requirements for hose in semiconductor manufacturing and we design our products to not only meet but exceed expectations.
Alloy selection: Penflex offers a variety of alloys tailored for safely handling the specialized gases and chemicals used in semiconductor manufacturing, including hydrogen fluoride, tungsten hexafluoride, sulfur hexafluoride, and nitrogen trifluoride. Our 316L stainless steel hoses are preferred, but in the most aggressive applications, hoses made from Hastelloy C-276 or Inconel 625 may be better options.
Clean ID technology: Penflex’s Clean ID hose is manufactured without internal tooling, lubricants, or forming fluid, resulting in a product free of the grease, moisture, oil, and particulate typically left behind by conventional manufacturing methods. The result is a truly clean inside diameter that eliminates the need for post-production cleaning and helps keep your operations running efficiently.
Superior cleanliness: In addition to our Clean ID options, we can accommodate customer-specified cleaning procedures—including oxygen cleaning services—upon request. To maintain cleanliness, all assemblies are individually bagged after preparation.
Corrosion resistance: All hoses are prone to deterioration if they’re continuously exposed to harsh substances and intense heat or pressures, but our austenitic stainless steel hoses have superior corrosion resistance. Their compatibility with fluorine-containing gases, aggressive etching chemicals, and cleaning and surface treatment substances means users can expect a longer lifespan than what is achievable with other materials.
Non-porous material: Semiconductor process gases can lose their effectiveness when exposed to even trace amounts of contamination, altering their chemical composition. Impermeable by nature, Penflex metal hoses create a secure barrier that prevents gas from permeating the hose wall and keeps external contaminants from entering the system.
Increased flexibility: Penflex’s compressed-pitch hose designs deliver superior flexibility, simplifying installation in tight or hard-to-reach spaces, an advantage in cleanrooms with compact layouts.
Leak testing: Each semiconductor hose undergoes the most sensitive leak testing method available. Using a mass spectrometer machine with helium gas, we can detect leaks as small as 10-12 cubic centimeters per second!
Quality welds: High-quality welds are essential to hose integrity and long-term performance, especially in fabs. At Penflex, we achieve this through a proven process that includes TIG welding and argon purging, which together produce clean, strong welds without compromising corrosion resistance. Our team includes ASME Section IX–certified welders, on-site certified welding instructors, and non-destructive examination (NDE) specialists, ensuring every assembly is tested and leak-tight before it leaves our facility.
