Rdl tsv bump wafer
WebWafer Bumping can be considered as a step in wafer processing where solder spheres are attached to the chip I/O pads before the wafer is diced into individual chips. The bumped dies can then be placed into packages or soldered directly to the PCB, i.e. the COB mentioned earlier. The advantages are many; lower inductance, better electrical ...

WebWafer bumping is a metal bump that grows on a wafer, and each bump is an IC signal contact. Unlike conventional interconnection through wire-bond, bond pads are placed at peripheral area , IO pads for bumping could be distributed all over the surface of the chip, thus chip size could be shrunk and electrical path could be optimized. WebDuPont Electronics & Imaging copper chemistries for redistribution layers (RDLs) are ideally suited to today’s high-density requirements, enabling RDL patterns for fan-out wafer level packages to meet next-generation line/space requirements down to 2 µm.
