A chip resistor includes: a board having a device formation surface, a back surface opposite from the device formation surface and side surfaces connecting the device formation surface to the back surface, a resistor portion provided on the device formation surface, a first connection electrode and a second connection electrode provided on the device formation surface and electrically connected to the resistor portion, and a resin film covering the device formation surface with the first connection electrode and the second connection electrode being exposed therefrom. Intersection portions of the board along which the back surface intersects the side surfaces each have a rounded shape.

A process is provided for forming an integrated thin film resistor (TFR) in an integrated circuit (IC) device including IC elements and IC element contacts. A TFR film layer and TFR dielectric layer are formed over the IC structure, and a wet etch is performed to define a dielectric cap with sloped lateral edges over the TFR film layer. Exposed portions of the TFR film layer are etched to define a TFR element. A TFR contact etch forms contact openings over the TFR element, and a metal layer is formed to form metal layer connections to the IC element contacts and the TFR element. The sloped edges of the dielectric cap may improve the removal of metal adjacent the TFR element to prevent electrical shorts in the completed device. A TFR anneal to reduce a TCR of the TFR is performed at any suitable time before forming the metal layer.
