Pros
As a design engineer, I crafted lid boxes for the Condor system, lift pin guides for the etching chamber, I modified the cathode for the G8 chamber, and designed a nanoswitch/phasorswitch box for a chamber assembly. In addition to my design experience, I also analyzed root cause of wafer breakages in the Carina chamber due to a plasma coating issue; in this project, I worked with a group of scientists to solve why wafer breakages were occurring. In another project, along with another scientist, I conducted wafer temperature uniformity measurements on Carina chamber to check temperature distribution over a number of trials. From my individual experience, I also learned how the Condor chamber is configured and lastly, I performed tests, loading wafers from foups to be plasma coated in the fab room.
Cons
In retrospect, I believe that if more guidance and more projects were provided, it would have improved my productivity and also the complexity of the projects would have been further developed and provided a method for developing more in-depth and detailed knowledge and work experience.
