About

This is a single-chamber tool for etching of a variety of materials. The chamber is configured as an ICP etching tool with 1250 W ICP power, 600 W RF substrate power, and RT-80°C operation with back-side He cooling and an electrostatic chuck to maintain controlled surface temperatures during etching. This chamber has Cl₂, BCl₃, CF₄, CHF₃, SF₆, Ar, N₂, He, and O₂ for gas sources and can be used to etch a variety of materials from SiO₂ to metals to compound semiconductors. The chamber evacuated with a 2000 lpm Osaka Vacuum magnetically levitated turbo pump, allowing for fast pump down. The system accepts 6” wafers (JEIDA Std) or pieces mounted to the wafers.
