| Typical roles for Tegal's etching systems used in MEMS and biochip fabrication include producing structures in silicon, silicon nitride, and silicon dioxide, in organic materials like BCB and polyimide and in noble metals, like platinum and gold. Catalytic combustion using raised temperatures (392-752F/200-400C) and supported catalyst beds, often used with noble metals such as platinum or palladium, can be very effective in reducing fumes to basic elemental constituents including nitrogen and hydrogen, and eliminating VOCS. Tests have proven a high content of noble metals from the tailings acquired from World Wide Consulting. |
