Discover HANDA’s RF/EMI Shielding Spiral Gasket made from premium Hastelloy C-276. Engineered for semiconductor CVD equipment, it delivers exceptional chemical resistance, high-temperature stability, and reliable RF/EMI attenuation for demanding plasma and vacuum process environments.

HANDA proudly introduces its latest high-performance innovation: the RF/EMI Shielding Hastelloy Spiral Gasket, specifically engineered for next-generation semiconductor CVD (Chemical Vapor Deposition) systems.
This new product combines advanced electromagnetic shielding capability, exceptional sealing reliability및 extreme chemical durability, making it a perfect fit for today’s demanding semiconductor manufacturing environments.

Semiconductor equipment is continuously evolving, requiring components capable of withstanding harsh plasmas, corrosive gases, thermal stress, and high-frequency electromagnetic interference. The HANDA Hastelloy C-276 spiral gasket was developed to solve these challenges with a single, integrated shielding and sealing solution.

1. Engineered for the Semiconductor Industry’s Most Extreme Conditions

Modern CVD tools operate under some of the harshest industrial conditions:

• High-temperature plasma reactions
• Rapid thermal cycling
• Chlorine, fluorine, and corrosive process gases
• Sensitive RF-powered plasma systems
• Precision vacuum sealing requirements

To address these challenges, HANDA’s spiral gasket uses Hastelloy C-276 strip, one of the most chemically and thermally resistant alloys available. The result is a gasket that offers stable mechanical integrity, reliable EMI shielding및 long service life in environments where traditional gasket materials fail quickly.

2. Hastelloy C-276: The Ideal Material for Harsh Semiconductor Processes–RF/EMI Shielding

Hastelloy C-276 is a nickel-chromium-molybdenum superalloy widely used in chemical processing, aerospace, high-temperature systems, and semiconductor production due to its unmatched resistance properties.

2.1 Outstanding Chemical Resistance

Semiconductor CVD equipment often exposes materials to corrosive chemicals such as:

• Chlorine (Cl₂)
• Hydrogen chloride (HCl)
• Fluorinated gases (NF₃, CF₄, SF₆)
• Plasma by-products
• Oxidizing and non-oxidizing acids

Hastelloy C-276 resists all of these with exceptional stability, preventing:

• Pitting corrosion
• Stress corrosion cracking
• Material embrittlement
• Surface degradation that can cause particle generation

For semiconductor manufacturers, maintaining cleanliness and avoiding contamination is crucial. Using a chemically resistant gasket like HANDA’s Hastelloy spiral gasket ensures stable performance, longer replacement intervals, and greater equipment uptime.

2.2 Extreme Heat Resistance

CVD processes typically operate at elevated temperatures, and the gasket must maintain both mechanical strength and shielding integrity.

Hastelloy C-276 offers:

• Excellent thermal oxidation resistance
• Stable mechanical properties across wide temperature ranges
• Resistance to creep and deformation during long compressive loads
• Reliability during rapid heating and cooling cycles

This makes it ideal for:

• Plasma CVD
• PECVD and LPCVD
• MOCVD reactors
• High-temperature vacuum connections
• Exhaust and chemical gas feed systems

When temperature stability is essential, HANDA’s Hastelloy spiral gasket delivers predictable performance.

3. Reliable RF/EMI Shielding for High-Precision Semiconductor Equipment

In semiconductor CVD systems, RF and electromagnetic interference can significantly impact:

• Plasma stability
• Film deposition uniformity
