Abstract
A method of fabricating a semiconductor package may include forming a plating layer on a surface of a substrate body. A circuit resist pattern and a monitoring resist pattern may be formed on the plating layer, and the plating layer may be etched using the circuit resist pattern and the monitoring resist pattern as etch masks, thereby forming circuit patterns and sub-patterns of a monitoring pattern. A residual rate of the circuit patterns may be monitored by inspecting the number of the sub-patterns of the monitoring pattern remaining on the substrate body after an etch process for forming the circuit patterns and the sub-patterns of the monitoring pattern. A semiconductor chip may be bonded to the circuit patterns using inner connectors.
