2.5D and 3D Semiconductor Package Technology: Evolution and Innovation

Sep 14, 2017 | Vern Solberg

The electronics industry is experiencing a renaissance in semiconductor package technology. A growing number of innovative 3D package assembly methodologies have evolved to enable the electronics industry to maximize their products functionality. By integrating multiple die elements within a single package outline, product boards can be made significantly smaller than their forerunners and the shorter interconnect resulting from this effort has contributed to improving both electrical performance and functional capability. (...)

This paper outlines both positive and negative aspects of current 3D package innovations and addresses the challenges facing adopters of silicon and glass based interposer fabrication. The material presented will also reference 3D packaging standards and recognize innovative technologies from a number of industry sources, roadmaps and market forecasts....

Embedding Passive and Active Components: PCB Design and Fabrication Process Variations

Jun 16, 2016 | Vern Solberg

Embedding components within the PC board structure is not a new concept. Until recently, however, most embedded component PC board applications adapted only passive elements. The early component forming processes relied on resistive inks and films to enable embedding of resistor and capacitors elements. Although these forming methods remain viable, many companies are choosing to place very thin discrete passive components and semiconductor die elements within the PC board layering structure. In addition to improving the products performance, companies have found that by reducing the component population on the PC board's surface, board level assembly is less complex and the PC board can be made smaller, The smaller substrate, even when more complex, often results in lower cost. Although size and cost reductions are significant attributes, the closer coupling of key elements can also contribute to improving functional performance.

This paper focuses on six basic embedded component structure designs described in IPC-7092....
