The Integrated ICP Etch Cluster comprises Metal etch module, Dielectric etch module and III-V etch module. It is capable to handle 8” wafer with up to 8 mass flow controlled gas lines for each module.
1. THE METAL ETCH MODULE
Metal etch module (W, Al, AlN tested)
InP grating etch
Cryo-cooled/electrically heated etch lower electrode, working temperature: -20C~70C
Standard gasline and MFC for nontoxic gases (SF6, Ar, O2, N2)
Bypassed gas line and MFC for toxic gas (Cl2, BCl3, HBr)
External gaspod gas line heating kit for low vapour pressure gases (BCl3)
2. DIELECTRIC MODULE
Standard gas line and MFC for nontoxic gases (SF6, Ar, O2, N2, C4F8, CHF3)
Bypassed gas line and MFC for toxic gas (Cl2)
3. III-V ETCH MODULE
Cryo-cooled/electrically heated etch lower electrode, working temperature: -20C~35C
Rapid cooling from cryo to chiller mode, from 200°C to 20°C in 40 minutes
Standard gasline and MFC for nontoxic gases (SF6, Ar, O2, N2)
Bypassed gas line and MFC for toxic gas (Cl2, BCl3, H2,CH4)
External gaspod gas line heating kit for low vapour pressure gases (BCl3)
