This disclosure provides systems, methods and apparatus for glass via bars that can be used in compact three-dimensional packages, including embedded wafer level packages. The glass via bars can provide high density electrical interconnections in a package. In some implementations, the glass via bars can include integrated passive components. Methods of fabricating glass via bars are provided. In some implementations, the methods can include patterning and etching photo-patternable glass substrates. Packaging methods employing glass via bars are also provided. |
