Patent ID: 8483997

Claim:
A computer program product for predicting electrical characteristics of a back end of line (BEOL) structure of a semiconductor integrated circuit (IC), the computer program product being tangibly stored on a non-transitory computer-readable medium, comprising: code executing on a computer to predict electrical characteristics of the BEOL structure having multiple layers comprising: an electrical resistance, R, of the BEOL structure based on input data specific to the multiple layers of the BEOL structure; an electron scattering characteristic of an inner filling material of the BEOL structure; and where R is based on: R = 4 ⁢ ( ρ 1 ⁢ H + ρ 2 ⁢ T t ) π ⁢ ⁢ CD eff 2 where H is the height of the BEOL structure, T t is the thickness of the outer liner, CD eff is an average of a top effective width and a bottom effective width, ρ 1 is width dependent resistivity of the inner filling material, and ρ 2 is bulk resistivity of the outer liner.
