The polycrystalline silicon thin films play an important role in the field of electronics. In the paper, α-SiAl composite membranes on glass substrates was prepared by magnetron co-sputtering. The contents of Al radicals encapsulated-in the α-Si film can be adjusted by changing the Al to Si sputtering power ratios.

The silicon-rich SiN(x) films were fabricated on Si(100) substrate and quartz substrate at different substrate temperatures varying from room temperature to 400 degrees C by bipolar pulse ane RF magnetron co-sputtering deposition technique. After deposition, the films were annealed in a nitrogen atmosphere by rapid photothermal annealing at 1050 degrees C for 3 minutes. This thermal step allows the formation of the silicon quantum dots.

In the present paper, nanocrystalline silicon thin films on glass substrates were prepared by rapid thermal annealing (RTA) of RF magnetron sputtered system and alpha-Si/Al films at a low temperature in Nz atmosphere. Optical metallographic microscope, confocal optical microscopy, X-ray diffractometer, Raman scattering and UV-Vis-NIR spectrometers were used to characterize the surface morphology and the phase and optical properties of nc-Si films. The influence of annealing process on the nc-Si films properties was studied.
