Foundry Landscape Changes In 3D


By Mark LaPedus Over the last year, leading-edge silicon foundries announced their new and respective strategies in the emerging 2.5D/3D chip arena. The ink is barely dry and now the foundry landscape is changing. One new vendor, Tezzaron Semiconductor, is entering the market. The 3D DRAM supplier plans to provide select 2.5D/3D foundry services within its recently acquired fab in Austin, T... » read more

Straight Talk On 3D TSVs


By Mark LaPedus Semiconductor Manufacturing & Design sat down to discuss 3D device challenges and applications with John Lau, a fellow at the Industrial Technology Research Institute (ITRI), a research organization in Taiwan. SMD: What is ITRI doing in 3D TSVs? Lau: At ITRI we have developed the world’s first Applied Materials’ 300mm (3D TSV) integration line. The line was comple... » read more

Options And Hurdles Come Into Focus For 3D Stacking


By Mark LaPedus The initial round of stacked 2.5D and 3D chips based on through-silicon vias (TSVs) has emerged in the market. There are other 2.5D/3D chips in the pipeline, but it’s taking longer than expected to bring these devices into production. There are a range of design, manufacturing, supply chain and cost challenges associated with 2.5D/3D designs. The enormous risk to bring ... » read more
