This paper describes manufacturing and application of getter for hydrogen, moisture and particulate to solve problem of degradation due to these contaminants. A brief history describing sources of hydrogen and mechanisms for device degradation by hydrogen is also presented in this paper.","PeriodicalId":433600,"journal":{"name":"1999 GaAs Reliability Workshop.
