Hi everyone! Can anyone out there tell me a bit about endpoint detection systems for Reactive Ion Etchers? What different types there are, how they work, what situations they are optimal for, andapproximate price ranges? I was told to write up a summary within the week regarding the possibility of either attaching one to our existing RIE (PlasmaTherm Batchtop) or getting another. (Wow! They actually came to me and offered to buy stuff, instead of me having to beg!!! Either I'm doing stuff really right, or really wrong!) Much thanks in advance, Marisa Ahmad R&D Specialist mahmad@semiconductor.com "It's not how hard you fall, it's how high you bounce."
