Abstract:
1. A method for manufacturing a substrate, comprising: providing a first supporting plate and two release films, the two release films being adhered on opposite sides of the first supporting plate being provided; forming a first wiring layer on each of the two release films; forming a first dielectric layer and a second wiring layer on each first wiring layer; defining a plurality of first conductive via-holes in the first dielectric layer, the first conductive via-holes electrically connecting the first wiring layer and the second wiring layer; defining a first penetrating room in the two first wiring layers, the first dielectric layer, and the second wiring layer; peeling the first wiring layer, the first dielectric layer, and the second wiring layer off from the first supporting plate to obtain the first wiring substrate; providing a second wiring substrate the second wiring substrate comprising a plurality of second connecting pads; and providing an adhesive sheet, the adhesive sheet defining a plurality of through holes and a second penetrating room, the through holes filled with a conducting material, the second penetrating room penetrating two opposite sides of the adhesive sheet; and orderly pressing the adhesive sheet and the first wiring substrate on the second wiring substrate, with the conducting material connected to the first connecting pads and the second connecting pads and the first penetrating room of the first wiring substrate and the second penetrating room of the adhesive sheet cooperatively forming a receiving recess.
