A contact via scheme with staggered contact vias to, interalia, increase current density of a resistor by mitigating electromigration and reducing the resistive heating of each contact via is disclosed. The contact via scheme increases the current density of a thin film resistor by increasing the number of current carrying contact vias and by arranging the contact vias in staggered arrangement, which redistributes the current at the ends of the resistor. Hence, the contact via scheme decreases the current density per contact via and enables a higher maximum current density for the resistor. A method and a semiconductor device are also disclosed.
A contact via scheme comprising:
A method of connecting a metal layer and a resistor on a semiconductor chip, the method comprising the step of:
A semiconductor device comprising:
