METHODS OF EMBEDDING THIN-FILM CAPACITORS INTO SEMICONDUCTOR PACKAGES USING TEMPORARY CARRIER LAYERS

摘要

Disclosed are methods of making a semiconductor package comprising at least one thin-film capacitor embedded into at least one build-up layer of said semiconductor package. A thin-film capacitor is provided wherein the thin-film capacitor has a first electrode and a second electrode separated by a dielectric. A temporary carrier layer is applied to the first electrode and the second electrode is patterned. A PWB core and a build-up material are provided, and the build-up material is placed between the PWB core and the patterned second electrode of said thin-film capacitor. The patterned electrode side of the thin-film capacitor is laminated to the PWB core by way of the build-up material, the temporary carrier layer is removed, and the first electrode is patterned.
