Provided are a tape substrate for a smart card, a method of fabricating the same, and a semiconductor module and a smart card using the tape substrate. The tape substrate includes at least one tape unit. The at least one tape unit includes a chip mounting unit defining a region on which a semiconductor chip is to be mounted, a plurality of pin electrode units arranged around the chip mounting unit and separated from one another, a border unit encircling the chip mounting unit and the pin electrode units, and a cutting unit disposed between the chip mounting unit and the border unit and between the pin electrode units and the border unit. The cutting unit includes a plurality of connection lines connecting the chip mounting unit and the pin electrode units to the border unit.
