High performance radio frequency (RF) front end filters were fabricated using glass interposer and 3D packaging technologies, especially through glass vias (TGV) and direct Cu metallization on the glass. Major challenges for the use of TGV in RF and electronics applications are the cost competitiveness, high throughput and reliable metallization of both TGV and flat glass surface with an excellent...
In this paper a glass-copper interface adhesion promoting thin film is described that forms chemical bonds with glass, and mechanically and possibly chemically anchors to copper to create strong, reliable adhesion between the glass substrate and the deposited metal. Wet chemical deposition of a low volatile organic content (VOC), emissions free, cost-effective, water based coating solution was used...
An economical and reliable copper metallization of dimensionally stable, non-conductive substrates, such as glass and ceramic, is becoming a major focus in electronic packaging technologies. Conventionally, adhesion on these substrates is achieved either by sputtering a thin metallic adhesive (Ti, Cr) followed by a copper seed layer or by high temperature lamination. This study has demonstrated that...
