Abstract:
1. A semiconductor structure having at least one corner includes: a carrier having a carrier surface, the carrier surface comprises a protection-layered disposing zone and a protection-layered exposing zone located outside the protection-layered disposing zone; a first protective layer disposed at the protection-layered disposing zone and having a first surface, the first surface comprises a first disposing zone, at least one first anti-stress zone and a first exposing zone located outside the first disposing zone and the at least one first anti-stress zone, wherein the at least one first anti-stress zone is located at the at least one corner and located between the first disposing zone and the first exposing zone; a second protective layer disposed at the first disposing zone and revealing the at least one first anti-stress zone and the first exposing zone, the second protective layer comprises a second surface, a first lateral side, a second lateral side and a first connection side connected to the first lateral side and the second lateral side, the second surface comprises a second disposing zone, at least one second anti-stress zone and a second exposing zone located outside the second disposing zone and the at least one second anti-stress zone, wherein the at least one second anti-stress zone is located at the at least one corner and located between the second disposing zone and the second exposing zone, wherein an extension line of the first lateral side intersects with an extension line of the second lateral side to form a first intersection point, the first connection side comprises a first point and a second point, wherein a zone formed by connecting the first intersection point, the first point and the second point is the at least one first anti-stress zone; and a third protective layer disposed at the second disposing zone and revealing the at least one second anti-stress zone and the second exposing zone, the third protective layer comprises a third lateral side, a fourth lateral side and a second connection side connected to the third lateral side and the fourth lateral side, wherein an extension line of the third lateral side intersects with an extension line of the fourth lateral side to form a second intersection point, the second connection side comprises a third point and a fourth point, wherein a zone formed by connecting the second intersection point, the third point and the fourth point is the at least one second anti-stress zone, the second connection side is projected on the first surface of the first protective layer to form a projection line parallel to the first connection side of the second protective layer.
