 Speech Abstract:

 Large Die Assembly Technology in TSV Package – Overcome the Die Warpag

With the increasing demand for high performance application, assembly of large dies becomes common in these days. As the die size increases, the warpage of the die is increased and the possibility of non-wetting also increases especially in CoS (Chip-on-Substrate) process. Currently two approaches are endeavored in Amkor. First, individual die’s warpage is controlled by adding inorganic layers with appropriate stress level. Second, dies are attached on a flat interposer or logic wafer ahead of bonding on an organic substrate, so called CoWoS (Chip-on-Wafer-on-Substrate). Amkor is adopting both technologies to provide high quality package with low coplanarity. This speech presents the TSV technology solutions for the back end processing of TSV based wafers, also referred to as MEOL and 2.5D/3D IC architectures assemblies
