Abstract:
1. A gas delivery device comprising: a first substrate unit and a second substrate unit, the first substrate unit and the second substrate unit each having a plurality of linear electrodes disposed on a principal surface of a substrate in a width direction and being electrically connected in a predetermined period in an arrangement order; and a drive voltage power supply unit configured to apply respective drive voltages with repeating patterns to the linear electrodes of each of the substrate units, the respective drive voltages with repeating patterns having a predetermined phase difference, wherein a gap is provided between the first substrate unit and the second substrate unit, and the principal surface of the substrate of each of the first substrate unit and the second substrate unit faces the gap, and wherein a frequency of at least one of the respective drive voltages applied to the first substrate unit and the second substrate unit is controlled.
