摘要
A nitrogen-implanted polysilicon thin film resistor has been proposed to improve the electrical characteristics of resistors in high-voltage CMOS technologies. The SIMS profile shows the proposed nitrogen-implanted polysilicon resistor can raise 100 times of the concentration of nitrogen. Thereby, the temperature coefficient of resistance (TCR), voltage coefficient of resistance (VCR), and mismatch are improved 20.4%, 35.9%, and 23.5% in average, respectively. The improvements are attributed to the suppression of both hydrogen intrusion by the presence of high-nitrogen concentration in polysilicon.
