My update on the particle generation in lampoly:
Inspecting my wafers before seasoning -> 2 particles or less per wafer
Inspecting my wafers after seasoning -> 8 particles or less per wafer
It didn't seem to be getting any better or worse with the number of
wafers run through the system. I ran 15 seasoning wafers, and 1
polysilicon wafer.
