Abstract:
1. A method for fabricating a three-dimensional aluminum package module, the method comprising: preparing an aluminum substrate having an upper surface and a lower surface; forming an anodization stop masking pattern on a predetermined portion of an upper surface of and an entire area of the lower surface of the aluminum substrate; anodizing the aluminum substrate having the anodization stop masking pattern to oxidize the aluminum substrate to a predetermined depth from the upper surface; removing the anodization stop masking pattern; forming a masking pattern on the anodized upper surface of the aluminum substrate and chemically etching the aluminum substrate to form an aluminum oxide layer having an opening which is perpendicular to the upper surface of the aluminum substrate; removing the masking pattern; mounting a device in the opening using an adhesive; forming an organic insulating layer on the device and the anodized upper surface of the aluminum substrate; and forming a circuit on the organic insulating layer and the aluminum oxide layer.
