BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a substrate processing apparatus,

The present invention relates to a substrate processing apparatus, and more particularly, to a substrate processing apparatus and a substrate processing method for increasing the deposition uniformity of a thin film deposited on a substrate.

Generally, in order to manufacture a solar cell, a semiconductor device, a flat panel display, etc., a predetermined thin film layer, a thin film circuit pattern, or an optical pattern must be formed on the surface of the substrate. For this purpose, A semiconductor manufacturing process such as a thin film deposition process, a photolithography process for selectively exposing a thin film using a photosensitive material, and an etching process for forming a pattern by selectively removing a thin film of an exposed portion are performed.

Such a semiconductor manufacturing process is performed inside a substrate processing apparatus designed for an optimum environment for the process, and recently, a substrate processing apparatus for performing a deposition or etching process using plasma is widely used.

A plasma processing apparatus using a plasma includes a plasma enhanced chemical vapor deposition (PECVD) apparatus for forming a thin film using plasma, and a plasma etching apparatus for patterning a thin film by etching.

1 is a schematic view for explaining a general substrate processing apparatus.

Referring to FIG. 1, a general substrate processing apparatus includes a chamber 10, a plasma electrode 20, a susceptor 30, and a gas injection means 40.

The chamber 10 provides a reaction space for the substrate processing process. At this time, the bottom surface of one side of the chamber 10 communicates with the exhaust port 12 for exhausting the reaction space.

The plasma electrode 20 is installed on the upper part of the chamber 10 to seal the reaction space.

One side of the plasma electrode 20 is electrically connected to an RF (Radio Frequency) power source 24 through a matching member 22. At this time, the RF power supply 24 generates and supplies RF power to the plasma electrode 20.

In addition, the central portion of the plasma electrode 20 is in communication with the gas supply pipe 26 for supplying the source gas for the substrate processing process.

The matching member 22 is connected between the plasma electrode 20 and the RF power supply 24 to match the load impedance and the source impedance of the RF power supplied from the RF power supply 24 to the plasma electrode 20. [

The gas injection means 40 uniformly injects the source gas to the entire portion of the reaction space through the plurality of gas injection holes 44 communicated with the gas diffusion space 42.

Such a general substrate processing apparatus loads the substrate W into the susceptor 30, and then sprays a predetermined source gas into the reaction space of the chamber 10 and supplies RF power to the plasma electrode 20. By forming a plasma in the reaction space between the susceptor 30 and the gas injection means 40, the source material of the source gas is deposited on the substrate W using the plasma.

Second, the uniformity of the thin film material deposited on the substrate W is uneven due to the nonuniformity of the plasma density formed in the entire upper region of the susceptor, and there is a difficulty in controlling the film quality of the thin film material.
