Ta_(2)O_(5) films are recognized as promising dielectric for future DRAM'S and the electrical properties of Ta_(2)O_(5) films greatly depend on the heating condition In this paper, the temperature effect was described by the electrical properties of W/Ta_(2)O_(5)/S_(1) structure when the heating temperature was vaned from 500 to 900 C in N_(2) for 30㎜ and the degree of temperature was 100℃.
In ln(J/E^(2)) Vs 1/E plot of typical I-V data, the Fowler-Nordheim tunneling could indicated as the dominant mode of current transports at low temperatures but, could not indicated as the dominant mode of current transports at temperatures above 700℃ due to crystallization of Ta_(2)O_(5) In the high frequency annealing temperature, and increases with annealing temperature, then we would induced to increasing of the densification.
