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. WebTable 2 shows the each layer thickness of 3-L RDL eWLB test vehicle. 3-layer RDL was prepared by the process flow shown in Fig. 3 with current HVM process equipments in eWLB/FlexLineTM. Table 1.
