the surface of the gluing layer 23 in an aligned manner by a pressing method although only two dice are shown in the related drawings it is not intended to limit the scope of the present invention with respect to the quantity of the die but serving as an example for the descriptions which follow the i o ports 241 of each of the two dice 24 are aligned with the vias 22 of the substrate 21 respectively after the two dice 24 are fixedly attached to the surface of the gluing layer 23 a plurality of fixing protective layers 25 is formed in the gap between the two dice 24 and the gaps between either of the two dice 24 and any other die not shown by a screen printing method it is noted that the fixing protective layers 25 can also be formed over the surface not shown of the two dice 24 by a screen printing method referring to fig6 a plurality of openings 221 is formed in the gluing layer 23 by laser drilling wherein the openings 221 are aligned with the plurality of vias 22 of the substrate 21 respectively referring to fig7 a plurality of metal contacts 26 is formed in the aforesaid vias 22 the openings 221 and part of the surface of the substrate 21 being electrical connecting to the i o ports 241 of.
