Please refer to fig. 1, fig. 2 to fig. 7, and fig. 8. FIG. 1 is a flow chart of a method of fabricating a strengthened glass structure according to one embodiment of the invention. Fig. 2 to 7 are process diagrams illustrating a method for manufacturing a strengthened glass structure according to an embodiment of the invention. FIG. 8 is a cross-sectional view of the strengthened glass structure of FIG. 7 taken along line A-A'. The method for manufacturing the package-strengthened glass structure 100 of the present embodiment will be described with reference to fig. 1 to 8, but not limited thereto. In some embodiments, steps may be added or deleted as desired.
As shown in fig. 1, fig. 2 and fig. 3, step S100 is performed to provide a mother glass substrate 110. The glass mother substrate 110 may be, for example, a large-sized glass substrate, and the length-by-width dimension thereof may be, for example, greater than or equal to 620 millimeters (mm) x750 mm, but is not limited thereto. In some embodiments, the size range of the glass mother plate 110 may be 620 mm x750 mm to 2880 mm x3130 mm. The size of the mother glass substrate 110 is 730 mm × 920 mm, but not limited thereto.
Next, after step S100, step S110 is performed to chemically strengthen the glass mother substrate 110 to form a first strengthening layer 120 on the outer surface 110S of the glass mother substrate 110. In some embodiments, the outer surface 110S includes a first surface 112, a second surface 114 and a side surface 116, wherein the first surface 112 and the second surface 114 are located on opposite sides of the mother glass substrate 110, and the side surface 116 is located outside the first surface 112 and the second surface 114, wherein the upper and lower sides of the side surface 116 are connected to the first surface 112 and the second surface 114. Also, in step S110, the first strengthening layer 120 may be simultaneously formed on the first surface 112, the second surface 114 and the side surface 116, that is, for example, six surfaces of the mother glass substrate 110 may be simultaneously chemically strengthened, as shown in fig. 3, but is not limited thereto.
For example, in the step S110, the chemical strengthening may be performed by ion exchange, so that the six surfaces of the glass mother substrate 110 generate surface stress through ion exchange, that is, the first strengthening layer 120 is formed, thereby enhancing the strength of the glass mother substrate 110, but is not limited thereto. The ion exchange method may be, for example, a sodium and potassium ion exchange method, and specifically, for example, the glass mother substrate 110 may be immersed in a potassium nitrate solution to exchange sodium ions of the outer surface 112 of the glass mother substrate 110 with potassium ions in the potassium nitrate solution, thereby generating a surface stress, so as to form the first strengthening layer 120 on the outer surface 112, but not limited thereto.
As shown in fig. 1 and 4, after the step S110, a step S120 is performed to form an anti-reflection layer 130 on the first surface 112 of the glass mother substrate 110, for example, the anti-reflection layer 130 may be formed on the first surface 112 of the glass mother substrate 110 by sputtering, evaporation, or coating. The anti-reflective layer 130 may be, for example, a composite film layer structure. For example, the anti-reflective layer 130 is a composite film structure formed by stacking high and low refractive index materials or high, medium and low refractive index materials, but is not limited thereto. Table 1 exemplarily shows the above-mentioned high, medium, and low refractive index materials and their corresponding refractive indices n (at a wavelength of 550 nm), but is not limited thereto.
TABLE 1
As shown in fig. 1 and 5, after the step S120, a step S130 is performed to form a stress buffer layer 140 on the second surface 114 of the mother glass substrate 110 to form a coated glass plate 150, wherein the first surface 112 and the second surface 114 are located on opposite sides of the mother glass substrate 110, that is, the stress buffer layer 140 is formed on a side opposite to the anti-reflection layer 130 to balance the residual stress generated by the anti-reflection layer 130. Wherein the stress buffer layer 140 may include silicon oxide (SiO)xSilicon oxide), silicon nitride (SiN)xSilicon nitride) or silicon oxynitride (SiO)xNy)。
As shown in fig. 1 and 6, after step S130, step S140 is performed to cut the coated glass plate 150 into a plurality of substrate units 160. For example, the large-sized coated glass plate 150 may be cut into a plurality of small-sized substrate units 160 along the dotted line DL by a cutting process (e.g., a wheel cutting process or a laser cutting process). The substrate unit 160 may be, for example, square, rectangular, or circular in the top view direction, but is not limited thereto, and a square is taken as an example in the present embodiment. Each substrate unit 160 formed after cutting includes a glass body 162, an anti-reflection layer 130, and a stress buffer layer 140, wherein the glass body 162 includes an upper surface 164, a lower surface 166 opposite to the upper surface 164, and a side surface 168 outside the upper surface 164 and the lower surface 166, wherein the upper and lower sides of the side surface 168 are respectively connected to the upper surface 164 and the lower surface 166. The anti-reflection layer 130 is located on the upper surface 164 of the glass body 162, and the stress buffer layer 140 is located on the lower surface 166 of the glass body 162. When the coated glass sheet 150 is cut into the substrate unit 160, the side ends thereof that are not chemically strengthened are exposed, that is, the side surfaces 168 of the glass body 162 of the substrate unit 160 that are not chemically strengthened are exposed. In contrast, the first strengthening layer 120 is still present on the upper surface 164 covered by the anti-reflection layer 130 and the lower surface 166 covered by the stress buffer layer 140, and the chemical strengthening effect is not removed.
As shown in fig. 1, 7 and 8, after step S140, step S150 is performed to chemically strengthen the substrate units 160 to form a second strengthening layer 170 on the side surface 168 of each substrate unit 160, thereby forming the strengthened glass structure 100. Since the side surface 168 of the glass body 162 of the substrate unit 160 exposed after the dicing is not chemically strengthened, the side surface 168 needs to be chemically strengthened to form a second strengthening layer 170. That is, the manufacturing method of the strengthened glass structure 100 of the present invention includes two chemical strengthening steps, in the finally manufactured strengthened glass structure 100, the first strengthening layer 120 formed by the first chemical strengthening step S110 is located on the upper surface 164 and the lower surface 166 of the glass body 162; the second strengthened layer 170 formed by the second chemical strengthening in step S150 is located on the side surface 168 of the glass body 162.
For example, in step S150, the chemical strengthening may be performed by ion exchange, so that the surface stress is generated on the side surface 168 of the glass body 162 of the substrate unit 160 by ion exchange, and the second strengthening layer 170 is formed, thereby enhancing the glass strength. The ion exchange method may be, for example, a sodium and potassium ion exchange method, and specifically, for example, the substrate unit 160 may be immersed in a potassium nitrate solution to exchange sodium ions of the side surface 168 with potassium ions in the potassium nitrate solution, thereby generating a surface stress, so as to form the second strengthening layer 170 on the side surface 168, but not limited thereto.
In addition, in the substrate unit 160, the anti-reflective layer 130 may be an ion exchange isolation layer to prevent the chemical strengthening effect in the step S150. For example, the anti-reflective layer 130 may be a composite film structure formed by stacking 4 to 10 or more than 10 films with a specific thickness range, but not limited thereto. In some embodiments, the anti-reflective layer 130 is Nb2O5Layer (optical thickness 200 to
)、SiO2Layer (400 to
)、Nb2O5Layer (2300 to
)、SiO2Layer (1100 to
) The layers are stacked from bottom to top along the direction D, and the optical thickness is calculated by multiplying the physical film thickness by the refractive index n (i.e. the optical thickness is the physical film thickness x refractive index), but the material and thickness of each layer are not limited thereto. In other embodiments, the anti-reflective layer 130 is SiOxNyLayer (optical thickness 300 to 300
)、SiO2Layer (400 to
)、SiOxNyLayer (2300 to
)、SiO2Layer (1100 to
) Stacking the layers from bottom to top along the direction D, but not limited thereto. Therefore, through the arrangement of the anti-reflection layer 130 and the film structure design thereof, the chemically enhanced ion exchange in the step S150 can be effectively isolated to avoid the warpage caused by the stress imbalance, and the influence on the spectrum of the anti-reflection layer 130 during the ion exchange can be further prevented. It should be noted that the composition of the anti-reflection layer 130 in the above embodiments is not intended to limit the thickness and material of each layer of the anti-reflection layer 130 and the number of stacked layers, and is only an exemplary embodiment of the invention.
Furthermore, in the substrate unit 160, the stress buffer layer 140 may be an ion exchange isolation layer to isolate the chemical strengthening effect in the step S150. For example, the stress buffer layer 140 may have a refractive index n of 1.85 (at a wavelength of 550 nm) and an optical thickness of 90 to
SiO of (2)xNyLayer, but not limited thereto. Therefore, by the configuration and the structural design of the stress buffer layer 140, the ion exchange chemically strengthened in step S150 can be effectively isolated to avoid warpage caused by stress imbalance, and the influence on the optical design of the whole strengthened glass structure 100 can be relatively insignificant.
In some embodiments, the method of manufacturing the strengthened glass structure 100 of the present invention further comprises: after step S140, the side surface 168 of each substrate unit 140 is selectively edged or polished. For example, the side surface 168 of the substrate unit 160 may be ground or polished by a Computer Numerical Control (CNC) machine to remove cracks or defects caused by the cutting process, thereby further improving the glass strength. In some embodiments, the substrate unit 160 may be chamfered by CNC, such as, but not limited to, a chamfered R angle or a chamfered C angle, etc., as required by the design.
Please refer to fig. 7 and fig. 8. As shown in fig. 7 and 8, the strengthened glass structure 100 according to an embodiment of the invention may include a glass body 162, an anti-reflection layer 130, and a stress buffer layer 140 by the manufacturing method described above. The glass body 162 includes an upper surface 164, a lower surface 166 opposite the upper surface 164, and a side surface 168. The upper surface 164 and the lower surface 166 each have a first reinforcing layer 120 and the side surface 168 has a second reinforcing layer 170. Wherein the first strengthening layer 120 and the second strengthening layer 170 are formed by different ion exchange processes. The anti-reflective layer 130 is formed on the upper surface 164 of the glass body 162, wherein the anti-reflective layer 130 may contact the first strengthening layer 120 and a portion of the second strengthening layer 170 located on the upper surface 164. The stress buffer layer 140 is formed on the lower surface 166 of the glass body 162, such that the stress buffer layer 140 and the anti-reflection layer 130 are in stress balance, wherein the anti-reflection layer 130 can contact the first strengthening layer 120 and a portion of the second strengthening layer 170 on the lower surface 166. In the present embodiment, the tempered glass structure 100 is a hexahedral structure, i.e., it includes a top surface (e.g., the upper surface 164), a bottom surface (e.g., the lower surface 166) and four side surfaces (e.g., a portion of the side surfaces 168), and the second strengthening layer 170 is formed in the side surfaces 168 of the glass body 162 on the four side surfaces, but not limited thereto.
Referring to fig. 9, fig. 9 is a schematic view of a strengthened glass structure according to another embodiment of the invention.
