Abstract
Provided is a semiconductor package including a semiconductor chip, a molding portion surrounding at least a side surface of the semiconductor chip, a passivation layer including a contact plug connected to the semiconductor chip and having a narrowing width further away from the semiconductor chip in a vertical direction, below the semiconductor chip, and a redistribution layer portion electrically connecting the semiconductor chip with an external connection terminal, below the passivation layer. The redistribution layer portion includes an upper pad connected to the contact plug and a fine pattern positioned at a same level as the upper pad, a redistribution layer and a via plug, which has a widening width further away from the semiconductor chip in the vertical direction, and a lower pad connected to the external connection terminal and exposed to an outside of the semiconductor package in a lower part of the redistribution layer portion.
