Abstract

The invention discloses an inductive coupling plasma device which is designed mainly for overcoming the influences of a geomagnetic field on ICPs (inductively coupled plasmas) and flexibly adjusting distribution of the ICPs. The inductive coupling plasma device at least comprises an inductive coupling generator and a plasma work chamber, wherein the inductive coupling plasma device is arranged at the position of an opening at the top end of the plasma work chamber; a compensation adjustment device is arranged on the inductive coupling plasma device; the compensation adjustment device is arranged outside or inside the inductive coupling generator and is used for compensating influences of the geomagnetic field and adjusting the density distribution of the plasmas. The inductive coupling plasma device can be used for effectively compensating the influences of the density distribution of the plasmas, and can be used for flexibly adjusting the density distribution of the plasmas by adjusting the magnetic strength and the direction of the magnetic field.
