Abstract
The two-dimensional temporal behavior of plasma was investigated at the wafer-level when applied power was turned on/off, which is one cycle of the pulsed plasma. For the measurement of transient plasma, the floating harmonic method and a post-processing method were used to obtain the ion flux and the electron temperature with a 1 ms time resolution. The results show that the transient behaviors of plasma such as antenna power absorption are observed in pulsed inductively coupled plasma. Antenna-shaped ion flux is observed when the power is turned on, and the radial profiles of the ion flux are followed by a diffusion solution when the power is turned off. Furthermore, the electron temperature shows pulsed plasma characteristics.
