Abstract
Accurate models of the contact region of an integrated circuit resistor are created in a single function. The function incorporates many contact geometries into a single function that cannot otherwise be represented by a closed form solution. A method of creating the function uses regression over the simulation results for many combinations of input variables. The function may use the contact resistance, metal trace resistance, and resistive area resistance as inputs to calculate the resistor contact region resistance.
