In 2010 DTU Nanolab acquired DRIE-Pegasus 1 (at the time called Danchip and DRIE-Pegasus, respectively). As a state-of-the-art etch tool with excellent performance and great flexibility, it grew immensely popular and by 2015 it was apparent that we needed yet another tool to cope with the demand. Therefore, in 2016 Pegasus 2 was acquired from a closed-down lab in Morocco and installed next to Pegasus 1.

Looking to expand our dry etching capabilities in 2017 we got an irresistible offer on a twin Pegasus system with cassette to cassette vacuum robot from a commerciel fab. The twin Pegasus system (called Pegasus 3 and 4) is installed at the old cluster 2 location in cleanroom C1 and will run only 6" wafers. Pegasus 3 is the 6" silicon etch work horse and Pegasus 4 is converted (adding extra process gases) into a 6" dielectric etch tool that will supplement/replace the AOE.

This page was originally intended as a regular one-machine page (the Pegasus 1 page). However, as of 2018 with several tools, the page will serve as common page for all of our Pegasi with subpages for each tool.

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.
