In the present embodiment, the conditioning device 110 includes a housing chamber 11〇1 and a heating portion 11〇2. The receiving chamber lioi is for accommodating a dopant solution to be vaporized. The heating portion n〇2 is used to supply heat to the dopant solution in the accommodating cavity 1101 to vaporize the dopant solution. Preferably, a carrier gas inlet may be disposed above the accommodating chamber 11 〇 1 of the vaporization device 110, and a carrier gas (such as nitrogen) is charged therein to cause the dopant solution to be vaporized by the carrier gas to enter the absorption tower. The liquid storage tank 111 is for storing the plating solution and supplying a coating solution to the absorption tower 12. The reservoir 111 has a valve 1110 for regulating the flow rate of the P coating solution entering the absorption tower 112. The absorption tower 112 is for allowing the plating solution to absorb the vaporized dopant solution to obtain a precursor solution. In the present embodiment, the absorption tower 112 is a plate type absorption tower' having an absorption chamber 1120. The absorption chamber 1120 includes a top portion 1121, a bottom portion 1122, and a plurality of trays 1123. The top portion 1121 is opposite the bottom portion 1122. The plurality of trays 1123 are located between the top portion 1121 and the bottom portion 1122 for sufficiently and uniformly mixing the vaporized dopant solution with the mineral film solution. The tray 1123 may be a sieve tray plate having a sieve opening having a pore diameter of 3_8 mm uniformly formed thereon. A liquid inlet 1124 is opened at the top portion 1121. The liquid inlet 1124 is used to communicate with the liquid storage tank 111 to allow the coating solution in the liquid storage tank m to enter the absorption chamber 1120', so that the mineral film solution can enter the absorption chamber 112 from the top 112i, and then pass through A plurality of trays 1123 flow toward the bottom 1122. The bottom 1122 of the absorption chamber 1120 is provided with an air inlet 1125 and a liquid outlet 1126. The air inlet 1125 is used for the vaporized dopant solution to enter the absorption chamber 112〇, so that the vaporized dopant solution can enter the absorption chamber 1120 from near the bottom 1122 and reach the tray 1123' through the mesh. When dispersed into a small stream of gas and passed through the coating solution layer in the form of bubbles and thoroughly mixed with the coating solution, a precursor solution having a better mixing effect is obtained. The liquid outlet 1126 is in communication with the thin film deposition apparatus 12 for outputting a precursor solution to the thin film deposition apparatus 12. Preferably, the precursor solution preparation device 11 further includes a microwave heating 6 201028214 device 113. The microwave force sigma heater H3 is disposed outside the absorption tower ill for heating the absorption tower 111 to facilitate film formation of the precursor solution into the thin film deposition apparatus 12. In this embodiment, the liquid inlet 1124 is opened at the top portion 1121, and the air inlet 1125 is opened at the bottom portion 1122. Therefore, during the absorption process, the coating solution is opposite to the flow direction of the vaporized dopant solution. It can be understood that the inlet U24 and the inlet U25 can be simultaneously opened at the top portion 1121, so that the coating solution in the absorption tower is mixed with the vaporized dopant solution in a cocurrent manner. Further, the tray 1123 is not limited to a sieve tray, but may be a float tray or a bubble tray. The absorption tower is not limited to a plate tower, but may be a packed tower or a turret. The film deposition apparatus 12 includes a nozzle 12 and a heating stage 123. The conduit / 21 is connected to a precursor solution preparation device for introducing the precursor solution into the thin film deposition device 12. Specifically, the conduit 121 is in communication with the liquid outlet 1126 of the absorption tower 112. The showerhead 122 includes opposing connection ends 124 and ejection ends 125. The connection end 124 is connected to the conduit 121. The discharge end 125 is opposite to the heating stage 123 and has a cross-sectional area larger than the cross-sectional area of the connection end 124. Preferably, the spray head 122 is coupled to a rotary cylinder that allows the spray head 122 to be rotated, thereby increasing the spray area of the spray head 122. The heating stage 123 is used to carry and heat the substrate to be coated. In order to prevent the precursor solution from entering the atmosphere and polluting the environment, the showerhead 122 and the heating station 123 are disposed in a sealed deposition chamber, and the deposition chamber 126 collects and processes the exhaust gas. Preferably, the thin film deposition device 12 may further include an ultrasonic atomizing device. The ultrasonic atomizing device may be disposed on the conduit 121 and the showerhead 122 for spraying the precursor solution into a micron-sized mist droplet and then spraying by the nozzle 122. A film is formed on the surface of the substrate to be coated. Thus, the precursor solution can be saved and the uniformity of the resulting film can be improved. Please refer to FIG. 2 hereinafter, the method of using the precursor film of the zinc oxide in the zinc oxide film to prepare the film preparation device 7 201028214 ίο, may include the following steps: The first step 'provides the coating solution 201 and the dopant solution 202. An ethanol solution of 0.09 mol/L of zinc acetate was placed as a coating solution 2〇1 and stored in the reservoir 111. An appropriate amount of gasification is dissolved in ethanol as a dopant solution 202 and placed in the accommodating chamber 1101. The amount of aluminum chloride in the dopant solution 202 depends on the amount of aluminum required in the zinc telluride film. In the second step, the substrate 100 to be coated is provided, placed on the heating stage 123, and the substrate 100 to be recorded is heated. The substrate 1 to be coated may be metal, glass, stone wafer or ceramic. In the present embodiment, the substrate 1 to be cast film is made of oxidized ginseng, and the substrate 100 to be coated is heated to 320. Hey. The third step is to make the vaporized dopant solution 202 enter the absorption tower 112 and flow from the bottom 1122 to the top portion 1121 while adjusting the valve ι 10 to bring the appropriate amount of the coating solution 201 into the absorption tower 112, so that the coating solution 201 is from the top 1121 to the bottom. During the flow in the 1122 direction, the vaporized dopant solution 202 is sufficiently uniformly mixed on the tray 1123 to form a precursor solution 200 having a better mixing effect. The dopant solution 202 in the accommodating chamber 1101 is heated to 11 Torr. (When left and right, the dopant solution 202 is vaporized. The vaporized dopant solution 202 enters the absorption chamber 1120 from the inlet 1125 at the bottom ❹ 1122. At the same time, the coating solution 201 enters from the inlet 1124 at the top 1121. The absorption chamber 1120 is mixed for about one hour, and the mineral film solution 201 can absorb most of the vaporized dopant solution 202 and obtain the precursor solution 200. Specifically, the vaporized dopant solution 202 is on the tray 1123. The bubble solution is dispersed in the coating solution 201. After the absorption is completed, the precursor solution 200 flows out from the liquid outlet 1126 of the bottom portion 1122, and the vaporized dopant solution 202 which is not completely absorbed can be from the top portion 1121 of the absorption tower 112. In the fourth step, the precursor solution 200 is guided to the thin film deposition device 12 to form a thin film on the surface of the substrate 100 to be coated. 201028214 ^ The body solution 200 reaches the junction of the showerhead 122 via the conduit 121 and is self-discharged. The end 125 is sprayed onto the surface of the substrate 1 to be heated to be coated with the film, and the == the body solution 2GG and the oxygen in the deposition chamber 126 are contacted with the oxidized lion sheet to form a zinc oxide film for the _Lu element. color Please refer to _ 3 for the SEM photograph of the zinc oxide film obtained by the embodiment of the technical solution. The fresh film, the above-mentioned film preparation device 1G precursor solution preparation device 11 includes a deposition device 110 and The absorption tower 112, the vaporization device 11 汽 the dopant solution vaporizes the 'absorption column 112, so that the mineral film solution can sufficiently absorb the vaporized dopant solution' to prepare the precursors of the respective precursors, thereby making the film deposition The film 12 obtains a film having a uniform phase. In addition, the film preparing device 10 can also conveniently control the components of the precursor solution 200.
