INTEGRATED ICP ETCH CLUSTERING SYSTEM System Overview 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: -150 ºC – +400 ºC 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: -150ºC-+400 ºC 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) Location: E6-05-09, Cleanroom Contact: e6nanofab@nus.edu.sg
