Web13. jan 2024 · Abstract. The reliability of a redistribution layers in 3D IC is dependent on how well the different shape and size of metal connection with varying density are connected at the different metallization levels. The widely different coefficient of thermal expansion of metal (Cu ~16.5 × 10−6 m/mK) and dielectric (SiO2 ~ 3 × 10−6 m/mK) often leads to … Web1. jan 2014 · Redistribution layer (RDL) is an integral part of 3D IC integration, especially for 2.5D IC integration with a passive interposer. The RDL allows for circuitry fan-outs of and allows for lateral communication between the chips attached to the interposer.
