Abstract
An alignment mark for determining a position of a thin film resistor formed on a semiconductor chip. The alignment mark is disposed on a capacitor formation region of the semiconductor chip. Because aluminum wiring members of the semiconductor chip are not disposed adjacent to the alignment mark within the capacitor formation region, the alignment mark can be precisely recognized. As a result, the position of the thin film resistor can be also precisely determined.
