Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2007-0118820 filed in Korea on Nov. 20, 2007, which is incorporated herein by reference. technical field

[0002] The invention relates to a thin film processing device. Background technique

[0003] Liquid crystal display devices, semiconductor devices (for example, solar cells), and the like are manufactured through various substrate-specific processes. For example, a thin film deposition process and a photolithography process and an etching process are performed several times to form a circuit pattern on the substrate, and additional processes such as a cleaning process, an attaching process, a cutting process, etc. are performed.

[0004] The deposition process and the etching process are performed in chamber type thin film processing equipment. Recently, PECVD (Plasma Enhanced Chemical Vapor Deposition) equipment in which a reactive gas is excited in plasma using RF (Radio Frequency) high vo...

Embodiment Construction

[0038] Reference will now be made in detail to the illustrated embodiments of the invention, which are illustrated in the accompanying drawings.

[0039] image 3 is a cross-sectional view illustrating a thin film processing apparatus according to a first embodiment of the present invention, and Figure 4 is to zoom in image 3 A view of area B.

[0040] see image 3 and 4 , the thin film processing apparatus according to the first embodiment includes a chamber 110 .

[0041] The reaction space A is in the processing chamber 110 and is a sealed space for performing a thin film processing process. The reaction space A is between the upper electrode 134 and the lower electrode 160 . The upper electrode 134 may be supplied with an RF high voltage, and the lower electrode 160 may be supplied with a bias voltage. The lower electrode 160 may serve as a chuck or a substrate replacement portion on which the substrate 102 is placed, and moves up and down.
