A method for forming a thin-film resistor includes forming two insulators on the thin-film resistor, forming contact holes by performing wet etching processes, and forming interconnect and contact plugs at the same time. The invention also provides another method for forming a thin-film resistor that forms a thin-film resistor over the passivation layer instead. That is, forming a thin-film resistor on the top of the device, so that the resistance can be re-modified according to the actual needs.
