Abstract

This Standard was technically approved by the 3DS-IC Global Technical Committee. This edition was approved for publication by the global Audits and Reviews Subcommittee on May 12, 2014. Available at www.semiviews.org and www.semi.org in August 2014.

 

This Guide is intended to address the needs of the 3D Stacked IC (3DS-IC) industry by providing the tools needed to procure processed wafers to be used in a 3DS-IC process.

 

This Guide provides the tools to describe individual wafers in a 3DS-IC process. In particular, this Document provides direction for describing the dimensions, materials, and devices for wafers that have undergone processing and are entering 3D stacking process steps. Since a 3D stacking process may include wafers from multiple fabrication facilities, it is important that this information is available to ensure additional process steps are performed correctly.

 

This Guide describes wafers and wafer stacks with nominal diameter of 300 mm and nominal thickness of 775 μm, although the actual wafer diameter and/or thickness may differ due to 3D stacking requirements and/or the effects of prior processing steps.
