AI Technical Summary

Technical Problem

Existing wafer adsorption arms are prone to breakage, the adhesive has a short lifespan and is prone to flowing into the air passages, causing blockages, and the metal plates are easily deformed during processing.

Method used

The metal wafer adsorption arm adopts a two-layer welded structure, with the gas path base plate cantilever and the gas path base plate adsorption end integrally formed. It has an internal vacuum channel and strengthens the structure by welding reinforcement plates to prevent adhesive from flowing into the gas path.

Benefits of technology

It improves the mechanical strength of the arm, avoids breakage and airway blockage problems, extends service life, and enhances the stability of wafer adsorption and the durability of the structure.
