Single Wafer Asher with Proprietary Microwave Plasma Source
The Automatic Single Wafer Asher GIGAfab LED is designed to serve
fabrication of opto-electronics, MEMS and power devices. It is equipped
with a unique microwave plasma source for high uniformity, providing
highly productive processing across a wide temperature range.
The modular platform can be configured for 100, 150 or 200 mm wafer size
with multiple cassette stations and up to three process chamber modules.
Each process chamber features a gravity wafer chuck with lift pins for
loading and unloading. It is thermoelectrically controlled from 65°C to
250°C. Wafers are loaded and unloaded by an atmospheric robot with dual
arm configuration for highest throughput. A cooling plate allows cool down
of the wafers prior to re-loading into the plastic cassettes. The chamber lid
is easy to open for maintenance access (clam shell opening).
System Performance
Wafer throughput: varying from 30-180 wafer/hour, depending on process
and number of process chamber modules. Temperature range for stripping:
100-250°C Uniformity: +/- 7.5% across 200 mm for Descum
