Patent ID: 11901322
Assignee: MAGNACHIP SEMICONDUCTOR, LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A semiconductor die, comprising:
a semiconductor substrate comprising a semiconductor die region and a seal-ring region;
an interlayer insulating film, a metal wiring, and a metal pad formed on the semiconductor substrate;
a passivation insulating film formed on the metal pad;
a metal bump connected to the metal pad;
an anisotropic conductive film (ACF) comprising conductive balls and formed on the semiconductor die; and
a flexible substrate attached to the ACF and curved toward the seal-ring region of the semiconductor die,
wherein a thickness of the interlayer insulating film disposed in the seal-ring region is smaller than a thickness of the interlayer insulating film disposed in the semiconductor die region.
