What is a Coin Style Single Wafer Shipper?

A Coin Style Single Wafer Shipper is a specialized packaging container designed for safely transporting, storing, and handling individual semiconductor wafers. Typically manufactured from high-purity, static-dissipative polymer materials, these shippers protect delicate wafers from contamination, mechanical damage, and electrostatic discharge (ESD).

Chemical Properties and CAS Number

• Material Composition: Typically polypropylene (PP) or polycarbonate
• CAS Number (Common Material – Polypropylene): 9003-07-0
• Appearance: Transparent or semi-transparent plastic, coin-shaped enclosure
• Static Dissipation: Excellent anti-static properties to prevent electrostatic discharge (ESD)
• Chemical Stability: Resistant to chemicals, corrosion, and environmental factors

Applications of Coin Style Single Wafer Shippers

1. Semiconductor Industry

Primarily utilized for secure transportation and storage of semiconductor wafers, maintaining cleanliness, minimizing damage risks, and preventing contamination.

2. Laboratory and Research

Used extensively in laboratory environments for safely handling sensitive silicon wafers, glass substrates, and other thin films requiring contamination control.

3. Photonics and Optoelectronics

Applied for protecting optical wafers, lenses, and photonic devices during transportation, ensuring high optical quality by avoiding contamination and damage.

4. MEMS (Microelectromechanical Systems)

Commonly employed in MEMS fabrication facilities to handle and protect delicate components from contamination, mechanical shock, and electrostatic interference.

5. Semiconductor Fabrication Facilities

Essential for safely transporting wafers between process steps, minimizing contamination risk and maintaining wafer integrity.

Pricing of Coin Style Single Wafer Shippers
