## Abstract

A semiconductor package may include a package substrate to which a first semiconductor chip is attached, an encapsulant covering the first semiconductor chip, and an indicator disposed within the semiconductor package. A side surface of the indicator is exposed at a side surface of the semiconductor package, and a width of a vertical section of the indicator parallel with the exposed side surface of the indicator varies as the vertical section of the indicator becomes farther from the side surface of the semiconductor package.

wherein the indicating blocks are arrayed in first to third columns which are sequentially disposed from the side surface of the semiconductor package toward the first semiconductor chip; and
wherein the number of the indicating blocks arrayed in the first column, the number of the indicating blocks arrayed in the second column, and the number of the indicating blocks arrayed in the third column are different from each other.

### Claim 9 (depends on 1)

The semiconductor package of claim 1, wherein the number of the indicating blocks which are exposed at the side surface of the semiconductor package varies according a distance between the side surface of the semiconductor package and the first semiconductor chip.

### Claim 10 (depends on 1)

The semiconductor package of claim 1, wherein the indicating blocks are disposed between the encapsulant and the package substrate.

### Claim 11 (depends on 1)

The semiconductor package of claim 1,
wherein the package substrate includes interconnection patterns; and
wherein the indicating blocks are located at the same level as the interconnection structure.

### Claim 12 (depends on 1)
