Semiconductor package

A semiconductor package comprising:

• a package substrate including a substrate pad;
• a first chip stacked structure comprising first chips including a first base chip mounted on an upper surface of the package substrate, and one or more first stacked chips sequentially offset-stacked on the first base chip such that each of the first stacked chips protrudes beyond a side surface of an adjacent lower first chip in a first direction;
• a second chip stacked structure comprising second chips including a second base chip offset-stacked along the first direction and mounted on an upper surface of an uppermost one of the first stacked chips of the first chip stacked structure, and one or more second stacked chips sequentially offset-stacked along the first direction on the second base chip such that each of the second stacked chips protrudes beyond a side surface of an adjacent lower second chip in the first direction;
• a third chip stacked structure comprising third chips including a third base chip offset-stacked along the first direction and mounted on an upper surface of an uppermost one of the second stacked chips of the second chip stacked structure, and one or more third stacked chips sequentially offset-stacked along the first direction on the third base chip such that each of the third stacked chips protrudes beyond a side surface of an adjacent lower third chip in the first direction;
• a bonding wire electrically connecting the substrate pad to at least one of the first chip stacked structure and the second chip stacked structure;
• a first support mounted on the upper surface of the package substrate, spaced apart from the first chip stacked structure in the first direction, and supporting the second chip stacked structure;
• and
• a second support spaced apart from the first and second chip stacked structures in the first direction and supporting the third chip stacked structure,
• wherein the first support supports the second chip stacked structure by supporting a lower surface of the second base chip,
• wherein the second support supports the third chip stacked structure by supporting a lower surface of the third base chip,
• wherein a center of each of the second chips does not vertically overlap the first base chip,
• wherein a center of each of the third chips does not vertically overlap the second base chip, and
• wherein the second base chip is a lowermost one of the second chips and the third base chip is a lowermost one of the third chips.
