Semiconductor package

A method of manufacturing a semiconductor package, the method comprising:

• preparing a first semiconductor chip, the first semiconductor chip including a first semiconductor substrate having an active surface and an inactive surface opposite to each other, and a plurality of first through electrodes penetrating at least a portion of the first semiconductor substrate;
• sequentially stacking a plurality of second semiconductor chip on the first semiconductor chip, each of the plurality of second semiconductor chip including a second semiconductor substrate having an active surface and an inactive surface opposite to each other, the active surface of the second semiconductor substrate facing the inactive surface of the first semiconductor substrate;
• forming a plurality of bonding pads between the first semiconductor chip and the plurality of second semiconductor and a chip bonding insulating layer surrounding the plurality of bonding pads;
• and
• stacking at least one supporting dummy substrate having a support bonding insulating layer on the plurality of second semiconductor chips, the support bonding insulating layer arranged on a lower surface of the at least one supporting dummy substrate;
• wherein at least some of the plurality of second semiconductor chips comprise a plurality of second through electrodes penetrating at least a portion of the second semiconductor substrate, wherein the plurality of bonding pads electrically connect the plurality of first through electrodes to the plurality of second through electrodes, and
• wherein a total vertical height of the at least one supporting dummy substrate is greater than respective vertical heights of the first semiconductor chip and the plurality of second semiconductor chips.
