摘要: a b s t r c UV excimer laser annealing (UV-ELA) is an alternative process that, during the last few years, has gained enormous importance for CMOS nano-electronic technologies, with ability to provide films and alloys electrical optical properties fit desired device performance. The UV-ELA of amorphous (a-) and/or doped nano-crystalline (nc-) silicon based on rapid (nanoseconds) formation temperature profiles caused by radiation that absorbed in material lead crystallisation, diffusion solid or even liquid phase. To achieve optimize parameters involved processing hydrogenated nanocrystalline (nc-Si:H) UV-ELA, numerical analysis finite element method (FEM) multilayer structure been performed. structures, consisting thin alternating a-Si:H(10 nm) n-doped nc-Si:H(60 layers, deposited glass substrate, also experimentally analyzed.
