WebMay 1, 2016 · A novel ultra-high-density InFO (InFO_UHD) technology with submicron RDL is developed to provide high interconnect density and bandwidth for logic-logic system and it is found that the scaling of RDL thickness, L/S, and dielectric thickness can mitigate ring-back problems in the eye diagram of organic substrate. 7 Highly Influenced WebThe typical thickness of high resolution DFRs are 7 µm, 10 µm, and 15 µm. For example, if 2 µm critical dimension is required, then with 7 µm DFR, the aspect ratio will be 3.5. Such high aspect ratio may lead to DFR collapse or bend even if the adhesion of DFR to the substrate is strong, affecting the yield of the whole panel, as shown in Figure 1. images pop ceilingWebSample: 20 nm Al Si-Kα energy resolution: 7.6 eV WDXRF (AZX 400), 103 eV EDXRF .
