E600L
Good uniform plasma processing in large area

Multi Spiral Coil type ICP

ICP????

• High density plasma without power-loss under low pressure
• Good etching uniformity in large area

Good control of wafer temperature by batch processing system

Multi wafer direct cooling system

 

• Good control of wafer temperature by direct chucking wafer
• High speed, good uniformity and good control of etching profile

 

Every single wafer is directly contacted to ESC, even multi-wafer etching in one batch.
Good cooling efficiency can realize HIGH RF Power, HIGH Etching Rate and HIGH Throughput.

 

Multi-wafer is transferred in a tray and etched at once.
The number of loading wafers on a tray depends on wafer size.

 

* According to Φ300 mm wafer processing, please consult us separately.
