摘要： Proposed is a package structure having a micro-electromechanical (MEMS) element, including a chip having a plurality of electrical connecting pads and a MEMS element formed thereon; a lid disposed on the chip for covering the MEMS element; a stud bump disposed on each of the electrical connecting pads; an encapsulant formed on the chip with part of the stud bumps being exposed from the encapsulant; and a metal conductive layer formed on the encapsulant and connected to the stud bumps. The invention is characterized by completing the packaging process on the wafer directly to enable thinner and cheaper package structures to be fabricated within less time. This invention further provides a method for fabricating the package structure as described above.
