Patent ID: 7403095

Claim:
A thin film resistor (TFR) structure comprising: a TFR; a first electrical interface portion directly coupled to a first end of the TFR; the first electrical interface portion comprising: a first layer of titanium (Ti) adjacent to the first end of the TFR, and a first layer of titanium nitride (TiN) formed on the first layer of Ti, wherein the first layers of Ti and TiN are located within a first opening formed in a first dielectric overlying the TFR; and a second electrical interface portion directly coupled to a second end of the TFR, the second electrical interface potion comprising: a second layer of Ti adjacent to the second end of the TFR, and a second layer of TiN formed on the second layer of Ti, wherein the second layers of Ti and TiN are located within a second opening formed in the first dielectric overlying the TFR; a second dielectric layer located on the first and second layers of TiN; a first contact extending through the second dielectric layer and contacting the first layer of TiN; and a second contact extending through the second dielectric layer and contacting the second layer of TiN.
