A microelectronic device includes a resistive differential alignment monitor (RDAM), including a first variable-width resistor and a second variable-width resistor, which are members of a conductor level. Each of the resistors include a wide portion and a narrow portion. The RDAM further includes a vertical connector to each of the wide portion and the narrow portion of the first variable-width resistor, and to the wide portion and the narrow portion of the second variable-width resistor. The vertical connectors are members of a vertical connector level. Test terminals are coupled to the vertical connectors.
