Coatings | Free Full-Text | Simulation and Optimization of Film Thickness …
At transverse position X 1 = 100 mm, the film thickness is 45% of the film thickness in the center position. Therefore, it can be concluded that as the distance from the target to the substrate, H, increases, the film thickness distribution in the transverse direction becomes more uniform, but the deposition rate decreases.
The ability to measure multiple photovoltaic thin-film layers quickly and reliably is critical for the development and manufacturing of thin-film solar cells. In this example, we are measuring both the buffer layer (CdS) and …
