Rainer re: "However, personell seems to be an issue, given they are still looking for a semiconductor process engineer and a semiconductor process technician."
I am not sure we can assume that "personell seems to be an issue", it may or may not be an issue. Another possibility is that POET is looking for more than one person to fill each role, so they may have already hired some people for these roles, and are looking for more. Just another way of thinking about this. Who knows?
