A semiconductor package includes a first semiconductor chip mounted to a substrate, a first encapsulant covering the first semiconductor chip and have first to fourth sidewall surfaces, and a chip stack mounted to the substrate and disposed on the first encapsulant. The chip stack includes a plurality of second semiconductor chips. A second encapsulant covers the chip stack. The second encapsulant may cover the first sidewall surface of the first encapsulant and expose the third sidewall surface of the first encapsulant.

Semiconductor package having plural semiconductor chips and method of forming the same

A printed circuit board (PCB) and a semiconductor package that are configured to prevent delamination and voids. In one example embodiment, the semiconductor package includes a PCB having a base substrate on which conductive patterns are formed and which includes an interior region having a die paddle for receiving a semiconductor chip and an exterior region disposed outside the interior region. The PCB also includes a first solder resist formed on a portion of the base substrate corresponding to the interior region and a second solder resist formed on a portion of the base substrate corresponding to the exterior region. The second solder resist may also have a greater surface roughness than the surface roughness of the first solder resist.

Printed circuit board and semiconductor package including the same

Provided are a semiconductor package in which bonding pads of a semiconductor chip are electrically connected to interconnection portions by wire-bonding, and a method of manufacturing the semiconductor package. The semiconductor package includes: a substrate; an interconnection portion that is disposed on the substrate and comprises conductive patterns having a first thickness and conductive patterns having a second thickness that is smaller than the first thickness; at least one semiconductor chip that is mounted on the substrate and comprises a plurality of bonding pads; and a plurality of wires electrically connecting the conductive patterns and the bonding pads.
