Definitions
- the present invention relates to a method of forming an organic thin film layer for an OLED using an organic material sputtering apparatus, a sputtering apparatus used for executing the method, To an apparatus for molding a target used in a sputtering apparatus.
- OLED is an abbreviation of active matrix organic light emitting diode. It is a kind of EL (electro luminescence) display using self-luminescent material when current is applied. Since a self-emitting material is used, it does not require a backlight like an LCD. Therefore, it is characterized by being able to realize low power consumption, light weight, and thin structure.
- the structure of the OLED generally includes a plurality of organic thin film layers as shown in Fig.
- the OLED organic thin film layer includes a hole injecting layer 102, a hole transporting layer 103, an emitting layer 104, and a light emitting layer 104, as well as a light-transmissive ITO that is an anode 101.
- the electron transport layer 105 may be formed of an electron injection layer,
- a thermal evaporation method and an E-beam evaporation method are used for depositing an organic material and a metal material to manufacture an OLED.
- Fig. 2 shows the concept of a thermal evaporation method.
- a crucible 202 containing a raw material 114 as a material to be deposited in the chamber 110 and a substrate 112 on which the raw material 114 is to be deposited are disposed.
- the crucible 202 is heated to melt the raw material 114, the melted raw material 114 is blown onto the upper substrate 112 and deposited.
- Figure 3 illustrates the concept of an E-beam deposition method.
- the chamber 120 is evacuated to a vacuum state by a vacuum pump 129 and an argon (Ar) gas is injected into the chamber 120 through the reaction gas supply unit 128, and an E-beam And the E-beam is rotated by the magnetic field to cause the target 114 to be irradiated with the E-beam.
- the rotated E-beam is melted by heating the raw material 114 and the melted raw material 114 is deposited on the substrate 112 disposed on the upper substrate holder 121.
- a sputtering deposition method as a method of depositing an arbitrary material on an arbitrary substrate.
- the sputter deposition method collides the activated particles with the target to release the target particles and allow the released target particles to deposit on the substrate.
- Sputtering can be used for all targets and substrates because it is a physical method without a chemical thermal reaction process.
- the RF sputtering deposition method can deposit an oxide or an insulator at a pressure lower than that of DC sputtering, and the dispersion of the target material during deposition is relatively smaller than that of DC sputtering, and thus is widely used in the deposition of nonmetal materials.
- a conventional OLED manufacturing method is as follows. First, ITO is deposited on the substrate in a sputtering chamber by a sputtering method to form the anode 101. Subsequently, a thin film of a metal such as the hole injection layer 102 and the hole transport layer 103 is formed on the anode 101 using a thermal deposition method or an E-beam deposition method in a thermal or E-beam deposition chamber . Next, an organic material is deposited on the substrate using a thermal deposition method or an E-beam deposition method in a separate organic material deposition chamber to which a lower temperature is applied in forming the metal thin film, thereby forming the light emitting layer 104.
- metals are deposited by a thermal deposition method or an E-beam deposition method to form an electron transporting layer 105 and an electron injecting layer 106. Finally, a metal such as aluminum or copper which serves as a cathode is deposited thereon.
- the thermal deposition method and the E-beam deposition method are methods for heating and evaporating the target material, it is difficult to uniformly control the deposited film thickness at the center and the upper and lower right and left portions as the substrate deposition target area is wider.
- the sputtering method can not be used.
- the impact energy applied to the target in the sputtering method is four times higher than the thermal energy applied to the target material in the thermal evaporation method or the E-beam evaporation method. By applying such high energy to the target, the organic target can be damaged.
- the energy of collision of the target material off the target with the substrate may be large and may be damaged during deposition.
- the organic material may be damaged by heat when the target of the OLED organic material used in the sputtering method is molded.
- OLED organic materials are impaired in properties at temperatures above 200 ° C. Therefore, if the sputtering target is manufactured by sintering at a conventional high temperature, the organic material is damaged and its characteristics are deteriorated. When the organic material is exposed to the atmosphere in the target manufacturing process, the characteristic of the organic material is damaged by binding with oxygen and moisture .
- the present invention seeks to solve the problems of various deposition methods and conventional manufacturing methods using various chambers. That is, an OLED is to be manufactured using only a sputtering deposition method by using a sputtering deposition method for depositing not only metals but also organic materials in OLED manufacturing.
- a method of forming a thin film layer of a luminescent organic material for an OLED using an RF sputtering apparatus comprising: forming a cathode in a chamber of an RF sputtering apparatus, Disposing a target including a target material for forming a thin film layer of a material and disposing a substrate on which the target material is to be deposited inside the chamber; Injecting a reaction gas after maintaining the inside of the chamber under vacuum; And applying a minimum RF power and a maximum magnetic field to the target such that plasma can be generated without damaging the target material.
