Abstract

A strip level substrate is manufactured by: applying solder resist on a substrate including a plurality of unit substrate divided by a scribe line; and patterning the applied solder resist to expose an electrode terminal and a ball land in each unit substrate, wherein the patterning of the solder resist is performed to be removed together with a solder resist part applied on the scribe line in order to reduce an early warpage of the strip level substrate.
