Embodiment 1
[0063] Attached below Figure 2-9 Illustrate the manufacturing method of embodiment 1 of the present invention:
[0064] 1. Prepare the glass substrate ( figure 2 );
[0065] 2. Open the first strip-shaped hole 2 with a certain depth on the first surface of the glass substrate 1, the first strip-shaped hole 2, wherein the first strip-shaped hole 2 is two parallel at a certain distance ( image 3 );
[0066] 3. Form a metal layer 3 on the first surface of the glass substrate by vapor deposition, wherein the metal layer fills up the first strip-shaped hole 2 ( Figure 4 ).
[0067] 4. Form a photoresist 4 on the surface of the metal layer 3, and then expose and develop it (for example, using a mask plate), wherein the first part 41 of the photoresist corresponding to the first strip hole 2 remains, and other positions are photoresisted. Glue removal ( Figure 5 ).
[0068] 5. the substrate is etched, so that the metal layer at the first strip hole 2 position remains to f...
