摘要: Competition between target erosion and compound layer formation during pulse cycles in reactive HiPIMS opens up the possibility of tuning discharge conditions properties deposited films by varying duty cycle situ without altering gas mixture. Three different systems, hafnium oxygen, tungsten oxygen/nitrogen, are studied which amorphous oxide (HfO2), (WO3), oxynitride (WOxNy) deposited. We show that cyclic evolution surface composition depends on including its affinity for mix melting point volatility. find length variations modulate hence chemistry The refractive indices HfO2 WO3 were progressively reduced with cycle, whereas WOxNy increased. These found to be d...
