Example of Polyimide film formation method – Episode of Spin Coat

🖊️Overview of the Spin-Coating Method for Polyimide

🫗Spin coating process

1. Dispense polyimide onto a glass substrate and spread it across the surface.

2. Rotate the glass substrate to evenly distribute the polyimide.

3. Subject the glass substrate to drying and curing processes.

4. Peel off the polyimide film from the glass substrate to complete the process.

🧙🏼Film thickness control in spin coating

1. Rotation speed,

2. Rotation time,

3. Solution viscosity,

4. Solution concentration,

5. Droplet volume,

6. Substrate condition

UBE’s UPIA-ST-1001 enables the production of low-CTE films, making it a preferred material for film substrates.
