Abstract:
An integrated circuit device, comprising:an integrated circuit chip; a plurality of devices formed in the integrated circuit chip; a scribe line formed at and defining the perimeter of the integrated circuit chip, said scribe line being used in separating the integrated circuit chip from other integrated circuit chips; a passivation film formed on the integrated circuit chip; a trench at a predetermined depth along the perimeter of the integrated circuit chip adjacent to the edge of the integrated circuit chip, the trench being formed at the scribe line at the perimeter of the integrated circuit chip, the predetermined depth being such that a boundary between multiple layers of the integrated circuit device intersects a sidewall of the trench; and an anti-moisture-absorption film in the trench at a predetermined thickness, said anti-moisture-absorption film covering the boundary between the multiple layers such that moisture is prevented from seeping into the edge of the integrated circuit chip.
