Abstract
The present invention relates to a thin-film resistor for an attenuator that is utilized in the fourth generation mobile communication, and more specifically, to a thin-film resistor having a Ti(N) thin film formed on an aluminum nitride (ALN) substrate. The thin-film resistor of the invention has superior electrical characteristics, such as sheet resistance, and superior characteristics in change of attenuation and voltage standing wave ratio (VSWR) with respect to changes of frequency and L/W, and thus the thin-film resistor can be utilized in a high frequency domain of up to 6 GHz.
