In this paper, we report on the deposition of aluminumdoped
zinc oxide films utilizing atmospheric pressure
plasma. The plasma was generated by flowing helium and
carbon dioxide, or oxygen, through two closely spaced
electrodes that were connected to a radio-frequency (RF)
power supply. The chemical precursors, diethylzinc and
trimethylaluminum, were mixed with the plasma just
downstream of the electrodes, and then directed onto glass
or silicon substrates heated to between 200 and 235 1C. The
precursors decomposed in the presence of the reactive gas
and formed the ZnO films. In earlier studies, this novel
plasma source has been used to grow amorphous hydrogenated
silicon [9], silicon dioxide [10], and silicon nitride
[11]. Herein, we examine the potential of atmospheric
pressure PECVD for the deposition of aluminum-doped
zinc oxide at low temperature.
