A plasma processing apparatus has a circular chamber having an opening portion which serves as a plasma ejection port surrounded by a dielectric member, a gas supply pipe for introducing gas into the inside of the chamber, a coil provided in the vicinity of the chamber, a high-frequency power supply connected to the coil, and a base material mounting table.

Plasma processing apparatus

A plasma processing apparatus having a dielectric member that surrounds a circular chamber having a long shape and communicating with an opening portion having a long and linear shape, a gas supply pipe for introducing gas into an inside of the circular chamber, a coil provided in a vicinity of the circular chamber and having a long shape in parallel with a longitudinal direction of the opening portion, a high-frequency power supply connected to the coil, a base material mounting table that mounts a base material, and a moving mechanism that allows relative movement between the circular chamber and the base material mounting table in a perpendicular direction with respect to an longitudinal direction of the opening portion.

To provide a plasma processing device and a plasma processing method capable of generating plasma stably and efficiently and processing the entire desired treated region of a substrate efficiently for a short period of time.

Plasma processing device, and plasma processing method

A plasma processing apparatus has a long chamber having an opening portion, a gas supply apparatus that supplies gas into the chamber, a spiral coil having a long shape in parallel with the longitudinal direction of the chamber, a high-frequency electric power supply connected to the spiral coil, a base material mounting table which is disposed opposite to the opening portion and holds a base material and a moving mechanism which is disposed in parallel with the longitudinal direction of the chamber and the longitudinal direction of the opening portion, and enables the chamber and the base material mounting table to relatively move perpendicularly with respect to the longitudinal direction of the opening portion.

In a plasma torch unit, copper rods forming a coil as a whole are disposed inside copper rod inserting holes formed in a quartz block so that the quartz block is cooled by water flowing inside the copper rod inserting holes and cooling water pipes. A plasma ejection port is formed on the lowermost portion of the torch unit. While a gas is being supplied into a space inside an elongated chamber, high-frequency power is supplied to the copper rods to generate plasma in the space inside the elongated chamber so that the plasma is applied to a substrate.
