Abstract
Description
The present invention relates to a gas injection apparatus, and more particularly, to a gas injection apparatus capable of preventing clogging of a nozzle and a thin film deposition apparatus having the same.
Generally, semiconductor memory devices, organic light emitting devices, and solar cells are manufactured using a semiconductor process. That is, a plurality of thin films are deposited and etched in a desired pattern to fabricate a device having predetermined characteristics. For example, in the thin film deposition process, the substrate is placed inside the chamber, heated to a predetermined temperature, and a process gas is injected to the substrate, whereby the process gas is decomposed by the heat of the substrate to form a thin film on the substrate.
At this time, an injection apparatus is used to uniformly inject the process gas onto the entire surface of the substrate. That is, an injection apparatus such as a gas injection plate or a shower head having a plurality of injection holes is provided at a position facing the substrate, for example, the upper side of the chamber, and the process gas provided from the outside of the chamber through the gas supply pipe is used to It is sprayed uniformly in the reaction space. On the other hand, the injection device for forming the organic thin film is provided with a heating means for vaporizing the organic raw material in powder form therein. An example of such an injection device is presented in Korean Patent Publication No. 2009-73359.
However, such an injection device is located inside the chamber, causing a lot of problems, one of which is clogging of the injection hole. This occurs because the temperature inside the injection device is higher than the temperature outside the injection device, ie the reaction chamber. That is, the inside of the injection apparatus maintains a high temperature in order to vaporize the raw material in the form of powder, and when the high temperature raw material gas is discharged to a lower temperature outside, particles are generated by the temperature difference, which causes clogging in the injection hole.
The present invention provides a gas injection apparatus and a thin film deposition apparatus having the same, which can prevent clogging of the injection nozzle.
The present invention provides a gas injection apparatus capable of preventing clogging of an injection nozzle using a gas injection speed, a replaceable injection plate, and the like, and a thin film deposition apparatus having the same.
Gas injection device according to an aspect of the present invention includes a body provided with a space therein; A plurality of injection holes formed on one surface of the body; And a plurality of spraying units provided in the plurality of spraying holes, respectively.
It further comprises a heating means provided in the body.
The plurality of injection units are provided with at least one of different diameters and lengths.
The plurality of injection units are provided with a length or a narrow diameter toward the edge from the center of one surface of the body.
The plurality of injection holes narrow in diameter from the center to the edge.
The plurality of injection units are densely arranged toward the edges from the center of one surface of the body.
The injection unit includes a protrusion provided to be narrow inward.
The plurality of injection units have one side open and the other side closed, and a plurality of holes are formed on the side.
The plurality of injection units are provided on a predetermined plate, and the plate is fastened to one surface of the body.
Gas injection device according to another aspect of the present invention includes a body provided with a space therein; A plurality of injection holes formed on one surface of the body; And an injection plate corresponding to each of the plurality of injection holes, a plurality of holes being formed and detachably coupled to one surface of the body.
The plurality of holes are formed to have a diameter smaller than that of the injection holes.
According to still another aspect of the present invention, there is provided a gas injection apparatus comprising: a deposition chamber in which a substrate is placed; A raw material supply unit for providing deposition raw materials in powder form; And a gas injector for vaporizing the deposition material in the form of powder and injecting the substrate in the deposition chamber, wherein the gas injector is provided in a plurality of ejection holes formed on one surface of a body having a space therein and is separable. And a plurality of injection units.
It further includes a rotation drive for rotating the gas injection unit.
Embodiments of the present invention is provided with a gas injection device including a plurality of injection units are detachably coupled in a plurality of injection holes formed in the lower body. The plurality of injection units may be provided to have a longer length or a narrower diameter from the central portion of the lower portion of the body to the edge, or the upper side may be opened and the lower side may be closed to form a hole in the side.
Therefore, the raw material gas is not injected through the injection hole but the raw material gas is injected through the injection unit fastened in the injection hole, so that clogging of the injection hole does not occur. In addition, since the injection unit is detachable, it is possible to reduce costs by separating and cleaning every predetermined cycle and reusing or replacing it with another injection unit.
