Plasma generation apparatus
First Claim
1. A plasma generation apparatus, comprising:
- a chamber having a chamber lid and defining an airtight reaction region;
a susceptor in the chamber;
a gas supply means supplying a process gas to the chamber; and
a toroidal core vertically disposed with respect to the susceptor through the chamber lid, comprising;
a toroidal ferromagnetic core combined with the chamber, the toroidal ferromagnetic core having a first portion outside the chamber and a second portion inside the chamber, the second portion having an opening portion;
a radio frequency (RF) power supply connected to the chamber;
an induction coil electrically connected to the RF power supply, the induction coil rolling the first portion; and
a matching circuit matching an impedance between the RF power supply and the induction coil.
