Abstract
A thermal enhanced low profile package structure and a method for fabricating the same are provided. The package structure typically includes a metallization layer with an electronic component thereon which is between two provided dielectric layers. The metallization layer as well as the electronic component is embedded and packaged while the substrates are laminated via a lamination process. The fabricated package structure performs not only a superior electric performance, but also an excellent enhancement in thermal dissipation.
Claims9
A method for fabricating an electronic package structure comprising steps of:
- (a) providing a first dielectric layer;
- (b)providing a leadframe-like carrier on said first dielectric layer, wherein said leadframe-like carrier comprises plural channels formed thereon for dividing said leadframe-like carrier into plural lead carriers;
- (c) providing an electronic component on one of said lead carriers;
- (d) providing a second dielectric layer on said electronic component and comprising plural first recesses formed thereon so that said first dielectric layer and said electronic component are covered therewith and a sandwich structure is formed thereby, wherein said leadframe-like carrier further comprises plural second recesses formed thereon and said electronic component is located in one of said second recesses being correspondingly to one of said first recesses;
- (e) performing a lamination process on said sandwich structure, so that said electronic component is embedded therein;
- (f) forming plural conductive members on said sandwich structure, wherein said conductive members pass through said second dielectric layer and are connected to said electronic component;
- and
- (g) patterning said sandwich structure.
