It should be noted that the method for fabricating the fingerprint identification device 20 of the present invention is not limited to the order of the following steps, and in other embodiments, the method for fabricating the fingerprint identification device 20 of the present invention may include only the following Some of the steps, or some of the steps, can be deleted. The method for fabricating the fingerprint identification device 20 according to the specific embodiment of the present invention will be described in detail below with reference to the description of the various process steps of FIG.
步驟S201，提供蓋板210，並在所述蓋板210的一表面212上開設缺口213。 In step S201, a cover plate 210 is provided, and a notch 213 is formed on a surface 212 of the cover plate 210.
具體地，請參閱圖4，首先提供一蓋板210，所述蓋板210包括相對的第一表面211與第二表面212；請參閱圖5，接著，用一噴霧裝置600通過噴霧的方式在該第二表面212的一預定位置持續噴射蝕刻液，以減少所述蓋板210在該預定位置處的厚度從而形成所述缺口213。請參閱圖6至圖8，在蝕刻所述蓋板210的過程中，可多次調整所述蝕刻液的濃度，將所述蝕刻液的濃度逐漸降低。可以理解，在剛開始蝕刻所述蓋板210時，蝕刻液的濃度較高，能夠快速地在蓋板210的第二表面212上蝕刻出凹陷，之後，逐漸降低所述蝕刻液的濃度，在快要蝕刻出所需要的缺口213的形狀時，由於蝕刻液的濃度被降低，所述蓋板210被蝕刻的速度從而也被降低，從而防止蝕刻過度的現象發生，以形成高精度的缺口213。在本實施方式中，在蝕刻所述蓋板210的過程可包括四個步驟，每個步驟使用不同濃度的蝕刻液分別對蓋板210進行蝕刻。即，可使用四種濃度的蝕刻液在不同的步驟分別對該蓋板210進行蝕刻，該四種蝕刻液的濃度按照其使用順序逐漸降低。 Specifically, referring to FIG. 4, a cover plate 210 is first provided, and the cover plate 210 includes opposing first surface 211 and second surface 212; please refer to FIG. 5, and then sprayed by a spray device 600. A predetermined position of the second surface 212 continues to eject an etchant to reduce the thickness of the cap plate 210 at the predetermined position to form the notch 213. Referring to FIG. 6 to FIG. 8 , during etching of the cover plate 210, the concentration of the etching solution may be adjusted multiple times to gradually reduce the concentration of the etching solution. It can be understood that the concentration of the etching liquid is high at the beginning of etching the cover plate 210, and the depression can be quickly etched on the second surface 212 of the cover plate 210, after which the concentration of the etching liquid is gradually lowered. When the shape of the desired notch 213 is to be etched, since the concentration of the etching liquid is lowered, the speed at which the cap plate 210 is etched is also lowered, thereby preventing the occurrence of excessive etching to form the high-precision notch 213. In the present embodiment, the process of etching the cap plate 210 may include four steps, each of which etches the cap plate 210 using different concentrations of etchant. That is, the cover plate 210 can be separately etched in different steps using four concentrations of etching liquid, and the concentrations of the four etching liquids are gradually lowered in accordance with the order of use thereof.
在本實施方式中，所述蝕刻液可以是氫氟酸(HF)與鹽酸(HCL)的混合溶液。蝕刻的總時間大約為50分鐘，蝕刻溫度大約為25攝氏度。當然，可以理解，在其它實施方式中，蝕刻的總時間與蝕刻溫度可根據實際情況調整。在本實施方式中，所述蝕刻液中氫氟酸的濃度為12%左右，所述鹽酸的濃度為7%至8%左右。在上述四個步驟的第一個步驟對所述蓋板210進行蝕刻所使用的蝕刻液包含的氫氟酸的濃度可大於12%，包含的鹽酸的濃度也可大於8%。而在該四個步驟的最後一個步驟所使用的蝕刻液包含的氫氟酸的濃度可小於12%，包含的鹽酸的濃度也可小於7%。 In the embodiment, the etching solution may be a mixed solution of hydrofluoric acid (HF) and hydrochloric acid (HCL). The total time of etching is approximately 50 minutes and the etching temperature is approximately 25 degrees Celsius. Of course, it can be understood that in other embodiments, the total time of etching and the etching temperature can be adjusted according to actual conditions. In the present embodiment, the concentration of hydrofluoric acid in the etching solution is about 12%, and the concentration of the hydrochloric acid is about 7% to 8%. The etching solution used for etching the cap plate 210 in the first step of the above four steps may contain a hydrofluoric acid concentration of more than 12% and a concentration of hydrochloric acid of more than 8%. The etching solution used in the last step of the four steps may contain a hydrofluoric acid concentration of less than 12% and a concentration of hydrochloric acid of less than 7%.
通過所述蝕刻液蝕刻所形成的缺口213，相較于傳統通過物理方式在蓋板210上鑽孔以形成缺口213的方法，該缺口213內表面的平整度更高。實驗表明，通過傳統的物理方式在蓋板210上鑽孔形成缺口後，該缺口內表面起伏的最高點與最低點之間的高度差通常會大於50um。而本發明中通過所述蝕刻液蝕刻所形成的缺口213，該缺口213內表面起伏的最高點與最低點之間的高度差小於1um。 The notch 213 formed by etching the etching solution has a higher flatness of the inner surface of the notch 213 than the conventional method of drilling a hole in the cover plate 210 to form the notch 213. Experiments have shown that after a hole is drilled in the cover plate 210 by a conventional physical method, the height difference between the highest point and the lowest point of the inner surface of the notch is usually greater than 50 um. In the present invention, the notch 213 formed by the etching solution is etched, and the height difference between the highest point and the lowest point of the inner surface of the notch 213 is less than 1 um.
在所述缺口213被開設在所述蓋板210的第二表面212上後，將所述蓋板210上殘留的蝕刻液洗淨，然後烘乾所述蓋板210。 After the notch 213 is opened on the second surface 212 of the cover 210, the etching liquid remaining on the cover 210 is washed, and then the cover 210 is dried.

The first colloid 261 is pasted on the second surface 212 where it is not covered by the light shielding layer 220, and partially extends to cover the light shielding layer 220.
在本實施方式中，所述第一膠體261與第二膠體262均選自透明光學膠。在本實施方式中，所述觸控模組251可以是單層或雙層觸控模組。在本實施方式中，所述顯示模組252可以是液晶顯示面板或有機發光二極體顯示面板。在其它實施方式中，所述觸控模組251可以與所述顯示模組252整合在一起，形成一內嵌式觸控顯示模組。 In this embodiment, the first colloid 261 and the second colloid 262 are both selected from transparent optical adhesives. In this embodiment, the touch module 251 can be a single layer or a double layer touch module. In this embodiment, the display module 252 may be a liquid crystal display panel or an organic light emitting diode display panel. In other embodiments, the touch module 251 can be integrated with the display module 252 to form an in-cell touch display module.
至此，所述指紋識別裝置20製作完成。 So far, the fingerprint recognition device 20 is completed.
