Abstract
A semiconductor package comprising plurality of bumps and fabricating method thereof. The package has a chip, a plurality of first and second bumps, an encapsulation, a redistribution. The chip has a plurality of pads and an active area and the active surface has a first area and a second area surrounding the first, the pads formed on a first area of the active surface, each first bump formed on the corresponding pad. The second bumps are formed on the second area, each second bump has first and second different width layers. The encapsulation encapsulates the chip and bumps and is ground to expose the bumps therefrom. During grinding, all of the first bumps are completely exposed by determining a width of an exposed surface of the second bump to electrically connect to the redistribution is increased. Therefore, a shallow-grinding or over-grinding does not occur.
