Low stress silicon carbide films with good uniformity in thickness and composition were deposited by varying the deposition parameters in a plasma enhanced chemical vapor deposition (PECVD) unit. The effects of deposition parameters on structure, chemical state and stress distribution of these films in the as deposited state were investigated.
Diamond coated silicon wafers are usually prepared by microwave plasma deposition. Here the maximum wafer diameter is between 4” (2.45 GHz excitation) and 8” (915 MHz excitation). Diamond disks are obtained by growing a thick diamond layer on a …
In this work we present a characterization of PECVD (plasma-enhanced chemical vapour deposition) amorphous silicon carbide films for MEMS/BioMEMS appliions. For this appliions a high deposition rate and a controllable value of the residual stress is required. The influence of the main parameters is analyzed. Due to annealing effect, the temperature can decrease the compressive …
