Abstract
A semiconductor package with stacked chips is proposed, wherein at least two chips are stacked on a chip carrier in a stagger manner as to dispose a second chip on a first chip, and a supporting element is disposed on the second chip and dimensioned to cover area on the second chip with no support from the first chip. The supporting element provides support to the second chip, allowing bonding wires to be successfully connected to the second chip, without the occurrence of cracks of the second chip. The supporting element can be formed on its lower surface with protruding portions positioned outside edge sides of the second chip; this is to enhance structural strength of the supporting element, and help maintain the second chip intact in structure during wire bonding. The supporting element can further have its upper surface to be exposed to the atmosphere; this improves heat dissipating efficiency of the semiconductor package.
