Abstract:
A method for depositing flexible high performance microbolometer detector material comprising:loading at least one wafer into a chamber;pumping down the chamber to a vacuum;setting a flow of argon into the chamber at a certain rate;calibrating a residual gas analyzer (RGA) so that the RGA can detect a spectrum of species of gases;setting the flow of argon gas for an ion gun wherein the argon is a sputtering gas;positioning a target of vanadium proximate to the ion gun;presputtering the target of vanadium;set a flow of oxygen into the chamber for presputtering;set the flow of oxygen into the chamber to a level that is adjusted at least partially with an RGA indication;activating ion gun to sputter with argon ions, vanadium atoms off of the vanadium target which combine with a certain portion of oxygen atoms in deposition on the at least one wafer, the portion of oxygen atoms determined by a setting of the flow of oxygen into the chamber; andsetting a timer for determining the duration of the deposition to attain a certain thickness of deposited material on the at least one wafer.
