Abstract
An integrated circuit device includes a first insulation layer formed on a substrate; a second insulation layer formed above the first insulation layer; a thin-film resistor formed on the second insulation layer; a third insulation layer in covering relation to the thin-film resistor and the second insulating layer; first contact holes penetrating the third insulation layer in association with the thin-film resistor; second contact holes penetrating through the second and third insulation layers; and conductive layers for electromagnetically shielding the thin-film resistor, the conductive layers including a first conductive layer formed between the first and second insulation layers below the thin-film resistor and a wiring layers formed above the thin-film resistor within the first and second contact holes.
