WebApr 4, 2024 · In this process, a femtosecond laser is utilized for the precise area-selective sintering of a thin layer of metal nanoparticles to define the source and drain contacts of the TFTs (in some cases also the gate electrodes). In the first step of this process, the substrate is uniformly coated with a layer of metal (usually silver) nanoparticles. Webrange using smaller steps should find the target doses. The operator should identify the highest and lowest doses that meet process criteria so as to have a usable range to …
