Abstract
A semiconductor device has an LSI chip including a semiconductor substrate, an LSI core section provided at a center portion of the semiconductor substrate and serving as a multilayered wiring layer of the semiconductor substrate, a first rewiring layer provided adjacent to an outer periphery of the LSI core section on the semiconductor substrate and including a plurality of wiring layers, a first pad electrode disposed at an outer periphery of the first rewiring layer, and an insulation layer covering the first pad electrode. The semiconductor device includes a second rewiring layer provided on the LSI chip and including a rewiring connected to the first pad electrode. The semiconductor device includes a plurality of ball electrodes provided on the second rewiring layer. The first rewiring layer is electrically connected to the LSI core section and the first pad electrode.
