Abstract

The semiconductor industry is driven by an increasing need of computation speed and functionalities. In the development of next generation devices the integration of more functionalities in an ever smaller volume becomes paramount. So far, classical planar integration was privileged but it is currently reaching its limits. One solution to this technological challenge is to consider the 3D dimension as pathway of integration. To ensure the vertical stacking of circuits, the development and control of assembly processes becomes crucial. Among the different techniques under development, direct bonding of metal thin films is a promising solution. It is a straightforward option that offers both a mechanical and an electrical link between the act...
