Abstract:
A method of making a package structure, comprising the steps of:providing at least two substrates for composing the package structure; making functional elements on at least one of the substrate; assembling discrete elements, dies and devices onto at least one of the substrate; forming part of electrical interconnection among the integrated elements and assembled discrete elements on one side or both sides of the said substrates; making electrical conduction line and lead line on at least one of the substrate for further constructing electrical conduction and signal connection between two different substrates; forming interposers, micro-joints and microstructures on a portion of surface of at least one of the substrate; aligning and pre-bonding a substrate with the said interposers, micro-joints and microstructures to another substrate; thereafter, the appropriate spacing provided by the corresponding said interposers, micro-joints and microstructures between the pre-bonded substrates, may accommodate and protect the integrated and hybrid assembled elements on the substrates; forming a completely scaled interface between the pre-bonded interfaces of substrates by encapsulating the interfaces via through-hole microstructures, therefore a completely sealed package interface of each packaged devices or apparatus in the form of the said package is done and separating each packaged structures, devices or apparatus in the form of the said package.
