Abstract

A method for manufacturing a substrate embedded with a passive device, comprising the steps of (a) molding the passive device and (b) mounting the molded passive device in a cavity formed on the substrate, is disclosed. The substrate embedded with a passive device and the manufacturing method thereof in accordance with the present invention can prevent warpage of the substrate caused by disproportioned properties of materials.

Claims (18)

1. A method for manufacturing a substrate embedded with a passive device, the method comprising:

preparing a substrate having a cavity formed therein;

preparing a molded passive device by applying a molding material on the passive device, the molding material being the same as the material of the substrate;

laminating a conductive material including an anisotropic conductive film (ACF) or an anisotropic conductive paste (ACP) on the cavity; and

mounting the molded passive device in the cavity,

wherein the applying the molding material on the passive device comprises

forming a patterned circuit on an insulating layer in accordance with an electrode formed in the passive device;

laminating a conductive material including an anisotropic conductive film (ACF) or an anisotropic conductive paste (ACP) on the circuit;

mounting the passive device on the conductive material;

removing the insulating layer; and

applying the molding material on the passive device.

2. The method of claim 1 , wherein a plurality of passive devices are mounted on the conductive material, and

the method further comprises separating the molded passive devices from each other after applying the molding material on the passive device.

3. The method of claim 1 , wherein the passive device is any one from a group consisting of a resistance, an inductor and a condenser.

4. The method of claim 3 , wherein the condenser is a multilayer ceramic condenser.

5. The method of claim 2 , wherein the material molding the passive device in applying the molding material is an epoxy resin.

6. The method of claim 2 , wherein, in separating the passive device, the passive device is separated in a hexahedral shape, using a saw.

7. The method of claim 2 , wherein, in separating the passive device, the passive device is separated in a cylindrical shape.
