'''SPTS process notation'''
Describing a process recipe on the Pegasus may sometimes be difficult because of the great flexibility of the instrument. A compact and precise notation is therefore required for the recipes. Click [[Specific_Process_Knowledge/Etch/DRIE-Pegasus/Notation|here]] to find a short description of the official SPTS notation.

'''Acceptance test'''
The instrument was opened for users in April 2010 when the acceptance test was signed. This was based on the performance of five standard recipes (A, B, C, D and SOI) that are further examined below. The acceptance test report is found [[Media:Pegasus_AcceptanceTest.pdf|here]].

A few hardware modifications have been made on the Pegasus since it was installed in 2010. The changes are listed below.


Other etch processes

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.
