Abstract:
1. A package structure having a Micro Electro Mechanical System (MEMS) element, comprising: a packaging substrate with a first surface having a first wiring layer disposed thereon and a second surface opposite to the first surface and having a second wiring layer disposed thereon, a plurality of conductive through holes penetrating the packaging substrate for electrically connecting the first wiring layer and the second wiring layer; a chip embedded in the packaging substrate and having a plurality of electrode pads exposed from the first surface of the packaging substrate; a first dielectric layer disposed on the first surface of the packaging substrate and the chip and having a plurality of openings for exposing a portion of the first wiring layer and the electrode pads of the chip; a third wiring layer disposed on the first dielectric layer and electrically connected to the first wiring layer and the electrode pads; a second dielectric layer disposed on the first dielectric layer and the third wiring layer and having a recessed portion and a plurality of blind vias penetrating the first and second dielectric layers; a lid disposed in the recessed portion and on a top surface of the second dielectric layer around a periphery of the recessed portion, wherein a portion of the lid on the top surface of the second dielectric layer is formed into a lid frame; a plurality of first conductive pads disposed on the second dielectric layer; a plurality of second conductive vias disposed in the blind vias penetrating the first and second dielectric layers so as to electrically connect the first wiring layer and the first conductive pads; an adhering material disposed on the first conductive pads and the lid frame; and a substrate having an MEMS element and a plurality of second conductive pads disposed on a surface thereof and attached to the packaging substrate with the MEMS element corresponding in position to the recessed portion.
