Hardware changes

Compared to a standard SPTS DRIE Pegasus chamber, the Pegasus 3 has had the same modifications as the Pegasus 1 with the exception of the Claritas EPD system. The changes are listed below.

The original (fast switching and with a maximum flow of 1200 sccm) SF6 MFC was causing problems for a long a time so it was replaced by two new MFC's:

  • SF6-1: Fast switching MFC for Bosch processes with a maximum flow rate of 600 sccm. It sits in the position of the old 1200 sccm MFC on top of the plasma source.
  • SF6-2: Normal MFC for continuous processes with a maximum flow rate of 100 sccm. It is installed in the gas cabinet next to the Ar MFC.


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.
