Integrated circuit package system employing wafer level chip scale packaging
View Patent ↗An integrated circuit package system that includes: providing a substrate with a protective coating; attaching a labeling film to a support member in a separate process; joining the protective coating and the labeling film; and dicing the substrate, the protective coating, and the labeling film to form the integrated circuit package system.
1. An integrated circuit package system comprising:
a substrate with a first surface and a second surface, the second surface includes a polished surface for promoting adhesion of subsequent layers;
electrical conductors on the first surface of the substrate;
a protective coating directly on the second surface of the substrate, the protective coating is optically opaque, and the protective coating includes a coating material having high adhesion strength, durability, and temperature resistance for preventing delamination and for providing structural support for the substrate; and
a labeling film on the protective coating, the labeling film includes a curable film having releasable bond properties, a sidewall of the protective coat coplanar to both a sidewall of the substrate and a sidewall of the labeling film.
2. The system as claimed in claim 1 wherein:
the protective coating can include a film type of material.
3. The system as claimed in claim 1 wherein:
the protective coating is a curable type of material.
4. The system as claimed in claim 1 wherein:
the protective coating exhibits temperature resistance.
5. The system as claimed in claim 1 wherein:
the protective coating supports and protects the substrate.
6. The system as claimed in claim 1 wherein:
the labeling film includes an identification mark.
7. The system as claimed in claim 1 wherein:
the labeling film includes a reverse image mark or a direct image mark.
8. The system as claimed in claim 1 wherein the protective coating can include a spray coating, a roll coating, a curtain coating, a brush-type coating, or a spin coating.
9. The system as claimed in claim 1 wherein the releasable bond properties include a chemical releasable bond or a thermal releasable bond.
10. The system as claimed in claim 1 wherein:
the substrate has a thickness of one hundred micrometers or less.
