摘要

This paper presents a comprehensive study of NiCr thin film resistors developed using a Trikon Sigma sputtering system on 150 mm wafers. The effects of sputtering process parameters and substrate conditions on resistivity and temperature coefficient of resistance (TCR) are discussed. A low energy deposition process with low power and high pressure has been developed to avoid NiCr thin film resistor edge oxidation and achieve high sheet resistance uniformity and low TCR.
