Abstract

A semiconductor. device comprises a semiconductor chip on which a plurality of grooves are defined, thus acting as a resisting member, the effect of which is to prevent the semiconductor chip from bending. Consequently, the thickness of the lower portion of the plastic layer becomes greater, thereby preventing cracks from occurring on the semiconductor chip.
