A semiconductor package includes a package substrate, a first semiconductor device on an upper surface of the package substrate, a second semiconductor device on an upper surface of the first semiconductor device, a first connection bump attached to a lower surface of the package substrate, a second connection bump interposed between and electrically connected to the package substrate and the first semiconductor device, and a third connection bump interposed between and electrically connected to the first semiconductor device and the second semiconductor device. The first semiconductor device has an edge and a step at the edge.

Semiconductor device and package including modified region of less density at edge of device or substrate

Semiconductor devices and methods for manufacturing a semiconductor device include a first semiconductor substrate in which a first scribe line region and a first chip region are defined, a first alignment mark inside the first semiconductor substrate and in the first scribe line region so as to be spaced apart from an upper side of the first semiconductor substrate, a second semiconductor substrate on the first semiconductor substrate and in which a second scribe line region and a second chip region are defined, and a second alignment mark inside the second semiconductor substrate and in the second scribe line region so as to be spaced apart from an upper side of the second semiconductor substrate, wherein the second semiconductor substrate is on the first semiconductor substrate so that positions of the first alignment mark and the second alignment mark correspond to each other.

Alignment mark for semiconductor device

A semiconductor device, a semiconductor package, and a package stack structure include a semiconductor substrate, a first bonding pad disposed on a first surface of the semiconductor substrate, and a first pillar disposed on the first bonding pad. An upper surface of the first pillar has a concave shape. Side surfaces of the first pillar are substantially planar.
