In semiconductor devices, breakdown voltage variation with temperature is a very significant study, since the reliability and performance of semiconductor devices especially depends upon the temperature. In this paper, the influence of temperature on breakdown characteristic of Ion Implanted edge terminated Co/n-Si Schottky Diode formed on n-Si epitaxial layer has been investigated by using SILVACO TCAD. It is also reported that not only resistive area present in close proximity to the edges of boron ion implanted Schottky diode are responsible for improvement in breakdown voltage but also the formation of PN junction near the edges, affect the breakdown voltage to a significant amount. The dopant concentration of epitaxial layer is 1 × 1015/cm3. The variation in reverse breakdown characteristics as a junction of temperature in the range of 300-1000 K is presented in this paper. A comparative study of breakdown voltages of Ion Implanted and as-prepared Schottky diode is also presented.
