Claim:
1. A semiconductor device, comprising: a semiconductor substrate; and a thin film resistor formed over an upper surface of the semiconductor substrate, the thin film resistor comprising a plurality of first thin film resistor units and a plurality of second thin film resistor units alternately arranged and connected in series, the first thin film resistor units being physically distinct from the second thin film resistor units, each of the first thin film resistor units having an elongated main portion and end portions that are respectively connected to respective ends of the elongated main portion, each of said end portions extending inwardly alongside and parallel to the elongated main potion to form a U-shape together with the elongated main portion in a plan view, and each of said end portions overlapping with adjacent one of the second thin film resistor units in the plan view and being connected to said adjacent one of the second thin film resistor units at an inner tip of the end portion.
