Pegasus 3 - 150mm silicon etching

The tool is already installed and ready to process.

The twin Pegasi (3 and 4) have just been rolled into the lab on July 3rd 2018.

The user manual(s), quality control procedure(s) and results, user APV(s) are not available, technical information and contact information can be found in LabManager:

Process information

Standard recipes

• Barc etch

Hardware changes

A few hardware modifications have been made on the Pegasus 3/4 since it was installed in 2019. The changes are listed below.

• Change of showerhead in 2019

• Addition of Picoscope oscilloscope system for process monitoring in February 2019

Other etch processes

• Continuous nanostructure etches including nano1.42

• Etch processes with DUV masks

• BARC etches

• Isotropic etches

More processes, such as for DUV resist, are currently being developed, but they are not quite 'ready for publication' at LabAdviser so please contact Jonas (mailto:jmli@dtu.dk) for more information.

Advanced Processing - Henri Jansen style

• Etch silicon nanostructures
• Etch high aspect ratio silicon microstructures
• Etch 3 dimensional silicon microstructures
• Etch black silicon
• Using OES to monitor etch process

Characterisation of etched trenches

Comparing differences in etched trenches requires a set of common parameters for each trench. Click HERE to find more information about the parameters used on the DRIE-Pegasus process development.
