Abstract
In this work we investigate device simulations for a sensitivity analyses on the PH25 single recess pHEMT process. The relation of the most critical process and epitaxial parameters on the electrical DC parameters are presented and discussed. The control of the recess etching is an important process module in stabilizing the electrical parameters. Improving the recess etching resulted in a significant reduced spread of the electrical parameters.
