520    This study investigated a variety of electrically 
       insulating materials for potential use as a gate 
       dielectric in thin-film transistor applications. The 
       materials that were investigated include silicon dioxide 
       and oxynitride films deposited using PECVD and LPCVD 
       techniques. Silicon source materials included 
       tetraethylorthosilicate (TEOS) and silane (SiH4). Oxygen 
       sources included diatomic oxygen (O2) and nitrous oxide (N
       2O). The optical, electrical, and material properties of 
       the dielectrics were analyzed using Variable Angle 
       Spectroscopic Ellipsometry (VASE), Fourier Transform 
       Infrared Spectroscopy (FTIR), Capacitance-Voltage (C-V) 
       analysis and current-voltage (I-V) analysis. Transistors 
       were also fabricated at low temperatures with different 
       gate dielectrics to investigate the impact on device 
       performance. While a deposited gate dielectric is 
       intrinsically inferior to a thermally grown SiO2 layer, an
       objective of this study was to create a high quality gate 
       dielectric with low levels of bulk and interface charge 
       (Qit & Qot∼1x1010 cm 2); this was achieved
