Cree|Wolfspeed

During the summer of 2021, I worked as a process engineering intern in the Cree|Wolfspeed Fab. The instrument of concern was used to active ions on the surface of a semiconductor wafer. The wafers were placed a few millimetres on top of each other and rested inside a cover that was not heating them evenly. I met with the physicist that designed the instrument to understand the reasoning behind certain geometries used in the instrument. I altered the cover and casing and ran resting using a pyrometer to collect the readings of multiple points across the surfaces of the wafers. With the new changes, more wafers could be ionized during each run.
