Embodiment Construction
[0042] Specific production methods, such as figure 2 Shown:
[0043] 1. Firstly, on the second substrate 100 (the material that can be used as the second substrate: N-type GaAs), use spin coating technology to coat a layer of organic polymer-polyimide with a thickness of 50-120 μm as Flexible substrate 200.
[0044] During spin coating, a unique spin coating method is used to first coat the low-viscosity polyimide (1800-2000cp) on the substrate by rotating at a high speed of 5000 rpm to form a uniform layer. Better basement membrane. Then reduce the rotation speed to 1000 rpm, and coat the high-viscosity polyimide (5000-6000cp) on the substrate with the base film while the substrate is rotating. A polyimide layer having a thickness of 50 to 120 μm is formed.
[0045] 2. After spin-coating, use photoresist mask technology to coat a layer of photoresist on the polyimide, and choose a low speed to uniform the coating, because the high speed will cause the previously coated p...
