Abstract

A method of fabricating a semiconductor device is disclosed. The method includes providing a substrate including an isolation region, forming a resistor over the isolation region, and forming a contact over the resistor. The method also includes implanting with a dopant concentration that is step-increased at a depth of the resistor and that remains substantially constant as depth increases.
