  • Patent number: 7960240
    Abstract: A buried thin film resistor having end caps defined by a dielectric mask is disclosed. A thin film resistor is formed on an integrated circuit substrate. A resistor protect layer is formed over the thin film resistor. First and second portions of a first dielectric material are formed over the resistor protect layer over the first and second ends of the thin film resistor. The resistor protect layer is then wet etched using the first and second portions of the first dielectric material as a hard mask. Then a second dielectric layer is deposited. A first via mask and etch process is used to etch vias down to the underlying portions of the resistor protect layer over the ends of the thin film resistor. A second via mask and etch process is used to etch substrate vias to an underlying conductor layer.

  • Patent number: 7808048
    Abstract: A buried thin film resistor having end caps defined by a dielectric mask is disclosed. A thin film resistor is formed on an integrated circuit substrate. A resistor protect layer is formed over the thin film resistor. A layer of dielectric material is formed over the resistor protect layer. The dielectric material is masked and dry etched to leave a first portion of dielectric material over a first end of the thin film resistor and a second portion of dielectric material over a second end of the thin film resistor. The resistor protect layer is then wet etched using the first and second portions of the dielectric material as a hard mask. Then a second dielectric layer is deposited and vias are etched down to the underlying portions of the resistor protect layer.
