摘要

A new reactor utilizing electron cyclotron resonance at 2.45 GHz is used for the deposition of microcrystalline silicon. Due to its planar geometry, such deposition process can be scaled for deposition onto large surfaces. Ultraviolet-visible ellipsometry, activation energy measurements and time resolved microwave conductivity (TRMC) measurements were made on the samples. The crystalline volume fraction obtained varied between 50% and 80%, as found by ellipsometry, and the growth rate is around 0.3 nm/s. The effective mobility is found to be between 1 and 6 cm(2) V-1 s(-1). The effect of the preparation conditions, such as substrate temperature, pressure, H-2 dilution and microwave power was investigated. This technology seems to be promising approach for the deposition of mu c-Si based thin film transistors. (C) 1998 Elsevier Science B.V. All rights reserved. [References: 13]
