Micropatterned Fluororubber-Based Dry Adhesive for Pan-Semiconductor Production Line with Complicated Operating...

Area of Science:

• Materials Science
• Surface Engineering
• Adhesion Science

Background:

• Precision materials handling in semiconductor production requires manipulation under vacuum, high temperatures, and low preload stress.
• Existing methods like suction gripping and mechanical clamping are inadequate for these complex conditions.
• Fluororubber (FKM) offers thermostability and vacuum compatibility but suffers significant adhesion loss at high temperatures.

Purpose of the Study:

• To develop an improved adhesive material for handling precision materials in challenging semiconductor manufacturing environments.
• To overcome the temperature-dependent adhesion decrease observed in conventional fluororubber films.
• To investigate the mechanism behind adhesion stabilization at elevated temperatures.

Main Methods:

• Fabrication of micropatterned fluororubber-based dry adhesives (MFAs) using laser etching.
• Experimental evaluation of MFA adhesion performance at high temperatures.
• Numerical analysis and in situ observation to understand the adhesion mechanism.

Main Results:

• Micropatterned MFAs demonstrate significantly restrained adhesion attenuation at high temperatures, with only a 15% decrease at 245 °C.
• This is a substantial improvement compared to unmodified FKM films, which experience an 84.83% decrease.
• The study elucidated the mechanism by which MFAs maintain adhesion under thermal stress.

Conclusions:

• Micropatterned FKM-based dry adhesives offer a contamination-free solution for manipulating precision materials in semiconductor production.
• MFAs provide high adhesion at low contact preloads, even under demanding conditions of temperature and vacuum.
• This technology is highly relevant for advanced semiconductor manufacturing lines with complex operational requirements.
