Refer again to Fig. 2 to Fig. 5.Fig. 2 to Fig. 5 depicts the schematic diagram of the first embodiment of the method for making Trackpad of the present invention.Hereafter the diagrammatic cross-section coordinating Fig. 2 to Fig. 5 to illustrate is described in detail the method for the making Trackpad of the present embodiment.As shown in Figure 2, first provide substrate of glass 10, wherein substrate of glass 10 has corresponding tin face 101 and an opposite face 102.In the present embodiment, there is tin face 101 and float glass technology (float glass process) can be utilized to be formed with the substrate of glass 10 of opposite face 102, but other technique be applicable to can not utilized as limit to be formed yet.Float glass technology comprises the following steps.Glass solution in molten condition is seated on solution of tin, the one side of glass solution is contacted with solution of tin, and the another side of glass solution is exposed in atmosphere.Then, solid-state substrate of glass 10 can be formed after in molten condition cooled and solidified.That is, in float glass technology, one of them surface of substrate of glass 10 can contact with solution of tin, and therefore tin ion can enter this surface of substrate of glass 10, therefore is called tin face 101; And another surface of substrate of glass 10 does not contact with solution of tin but exposes in atmosphere, therefore exist without tin ion in fact, therefore be called opposite face 102.
As shown in Figure 3, then barrier layer 12 is formed at the opposite face 102 of substrate of glass 10.Barrier layer 12 has barrier function, can enter substrate of glass 10 by barrier ion via opposite face 102.In the present embodiment, barrier layer 12 contacts with the opposite face 102 of substrate of glass 10, but not as limit.Barrier layer 12 can be single layer structure or multilayer lamination structure.Barrier layer 12 can utilize physics mode, chemical mode or other applicable mode to be formed in the opposite face 102 of substrate of glass 10, such as, attach, be coated with, electroplate, physical vapour deposition (PVD) or chemical vapor deposition etc., but not as limit.The material of barrier layer 12 can comprise inorganic material, organic material or organic/inorganic hybrid material, such as monox (SiO
x), silicon nitride (SiN
y), silicon oxynitride (SiN
xo
y), but not as limit.The material of barrier layer 12 also can be metal or metal oxide such as titania (TiO
2), tantalum pentoxide (Ta
2o
5) or niobium pentaoxide (Nb
2o
5).Different according to application, barrier layer 12 can be photic zone or light non-transmittable layers.Such as when Trackpad is applied in the display surface of display device, barrier layer 12 is photic zone, and when Trackpad is applied in other non-display device, barrier layer 12 can be light non-transmittable layers.In addition, the thickness of barrier layer 12 can be adjusted with the difference of material, and such as the thickness of barrier layer 12 in fact can between 1 nanometer (nm) to 100 nanometers, and can between 1 nanometer to 30 nanometer, but not as limit.In addition, the refractive index of barrier layer 12 can be considered according to different optics and be greater than, is less than or equal to the refractive index of substrate of glass 10.
As shown in Figure 4, carry out a reinforcement process such as chemical enhanced technique, the substrate of glass 10 being formed with barrier layer 12 is immersed reinforced solution 14.Reinforced solution 14 comprises multiple ion 16, and has another kind of ion in substrate of glass 10, and wherein the size of the ion 16 of reinforced solution 14 can be greater than the ion that substrate of glass 10 comprises itself.For example, reinforced solution 14 can be potassium nitrate solution, and therefore ion is potassium ion, and the ion that substrate of glass 10 comprises itself is such as sodion.In reinforcement process, ion exchange can be produced by spreading between substrate of glass 10 and reinforced solution 14 and react.That is, the larger-size potassium ion in reinforced solution 14 can enter in substrate of glass 10 position of the less sodion of the size replaced in substrate of glass 10 and reach the effect of tempered glass substrate 10.Size herein can refer to ionic radius or atomic radius.What deserves to be explained is, it is potassium ion that the ion 16 of reinforced solution 14 does not limit, and the ion of substrate of glass 10 not limit be sodion.For example, when the ion of substrate of glass 10 is lithium ion, then the ion 16 of reinforced solution 14 can be the ion that any size is greater than lithium ion, such as sodion or potassium ion.
