Tweezers

Wafer Tweezers

Wafer tweezers grip semiconductor wafers at the edge or from below without touching the active surface. Instead of pointed ends they carry a stepped paddle, either with 3, 4 or 5 teeth as defined contact points or without teeth for scratch sensitive surfaces. Versions with polyester, PTFE or pyroplast tips avoid metal contact with the wafer, and ESD variants are dissipative to IEC 61340-5-1 at 10⁶ to 10⁹ Ω. The category holds 15 articles from Bernstein and Weller for wafer diameters from 3 to 6 inch.

How to choose Wafer Tweezers

What matters when choosing: properties, comparison and typical applications.

Technical Features

⚡ Stepped paddle instead of a tip - edge handling without contact to the active wafer surface

⚙ Shapes 3 DW, 3 DWF, 4 DWF, 5 DWF and 6 DW - without teeth or with 3 to 5 teeth as contact points

↕ Polyester and PTFE tips - no metal contact with the wafer surface

✓ Lengths 130 and 150 mm - matched to wafer diameters from 3 to 6 inch

✓ ESD version to IEC 61340-5-1 - dissipative stainless steel, 10⁶ to 10⁹ Ω

Paddle shapes compared

Shape	Paddle	Use
3 DW	stepped, no teeth	flat edge handling
3 DWF	stepped, 3 teeth	defined contact points
4 DWF	stepped, 4 teeth	medium wafer diameters
5 DWF	stepped, 5 teeth	larger wafers
6 DW	no teeth, matt polished	scratch sensitive surfaces

Typical Applications

Typical applications: Handling silicon wafers in semiconductor production and metrology; loading and unloading wafer cassettes; work under cleanroom conditions; loading and inspection at wafer probers and microscopes; handling substrates and glass plates in thin film technology; research and laboratory work with wafers from 3 to 6 inch.
