Precision Patterning: Delivers accurate ablation for the P1, P2, and P3 processes, essential for structuring the front contact, intrinsic layers, and back contact without damaging underlying layers.
Customer Service
There are two possible solutions to overcome these limitations: using a wavelength where the absorption in the covering layer is sufficient and the base layer is transparent or shifting the ablation
