The development of the technology of fabricating hydrogenated amorphous silicon (a-Si:H) or silicon oxide (SiOx)
matrix with nanocrystalline inclusions (nc-Si:H) is the next step in improving the properties of electronic devices, such
as solar cells, thin film transistors (TFT), floating gate transistors and others. Those films exhibit increased stability,
absorption and carrier mobility. This paper is focused on the technology of manufacturing such films by means of Radio
Frequency Plasma Enhanced Chemical Vapor Deposition (RF PECVD), which is use to fabricate electronic devices. The
technology was developed in the Semiconductor Thin Films and Solar Cells Laboratory at the Department of Electronics
at the AGH University of Science and Technology. The author describes the manufacturing process based on periodical
variation of the process parameters, such as hydrogen to silane ratio (Rh), gas flows, RF power and pressure in the
process chamber, during the deposition process. The author also presents the results of the measurements of typical
samples with High Resolution Transmission Electron Microscopy (HRTEM), which confirms the existence of the
nanocrystallites in the a-Si:H/SiOx matrix.
