Abstract:
A method is provided for forming an integrated thin film resistor (TFR) in a semiconductor integrated circuit device. A first dielectric layer is deposited on an integrated circuit (IC) structure including conductive contacts, a resistive film (e.g., comprising SiCCr, SiCr, CrSiN, TaN, Ta 2 Si, or TiN) is deposited over the first dielectric layer, the resistive film is etched to define the dimensions of the resistive film, and a second dielectric layer is deposited over the resistive film, such that the resistive film is sandwiched between the first and second dielectric layers. An interconnect trench layer may be deposited over the second dielectric layer and etched, e.g., using a single mask, to define openings that expose surfaces of the IC structure contacts and the resistive film. The openings may be filled with a conductive interconnect material, e.g., copper, to contact the exposed surfaces of the conductive contacts and the resistive film.

Claim (Index 1):
A method of forming an integrated thin film resistor (TFR) in a semiconductor integrated circuit device, the method comprising:\n forming an integrated circuit structure including at least one conductive contact; forming a first dielectric layer over the integrated circuit structure; forming a resistive film over the first dielectric layer; forming a second dielectric layer over the resistive film, such that the resistive film is arranged between the first and second dielectric layers; forming an interconnect trench layer over the second dielectric layer; performing at least one etch process to define openings that expose both (a) at least one surface of the at least one conductive contact and (b) at least one surface of the resistive film; and at least partially filling the openings with a conductive interconnect material to contact the exposed surfaces of the at least one conductive contact and the resistive film.
