My team and I at Guardion are working on a National Science Foundation grant building a new type of vacuum gauge based on novel nanomaterial technology. It will potentially be capable of operating in atmosphere to ultra high vacuum. We are new to Semicon and wanted to learn more about how vacuum gauges are incorporated in a fab ie. how many are used, what is the cost associated with them, maintenance requirements etc. My email is [email protected]. We really appreciate your help!
