3-D Technology Assessment: Path-Finding the Technology/Design Sweet-Spot

It is widely acknowledged that three-dimensional (3-D) technologies offer numerous opportunities for system design. In recent years, significant progress has been made on these 3-D technologies, and they have become probably the best hope for carrying the semiconductor industry beyond the path of Moore's law. However, a clear roadmap is missing to successfully introduce this 3-D technology onto the market. Today, a plurality of 3-D technology options exists, which requires different design and test strategies. To crystallize the many technology options in a few mainstream technologies, it is mandatory to coexplore both technology and design options. The contribution of this paper is to introduce a novel path finding methodology to untangle the many intertwined design/technology options. This holistic approach will be applied on a representative 3-D case study. Initial results demonstrate the benefits of the proposed path-finding methodology to steer the technology development and fine-tune design strategies.
