Copper sulfate plating additive optimal for semiconductor package substrate implementation.
Topluchina FRV, a copper sulfate plating additive that achieves both high filling capability and in-plane uniformity, is optimal for the implementation of semiconductor package substrates.
In the implementation of semiconductor package substrates, attention is being drawn to Fan-Out Wafer Level Packaging (FOWLP) technology. In the case of FOWLP, wiring (redistribution layer) is formed in the internal area of the semiconductor package substrate. In traditional bump connections, it was necessary to electrically connect the semiconductor chip and the terminals of the package substrate. Additionally, in wire bonding using fine wires of gold or aluminum, there was a problem where increasing the number of terminals made it difficult to achieve reliable electrical connections. Therefore, the practical application of fan-out packaging technology, which allows multiple chips to be mounted side by side (multi-chip) without limitations based on chip size, is rapidly advancing. Our company has newly developed a copper sulfate plating solution that enables high filling and in-plane uniformity for the formation of redistribution layers on semiconductor wafers.
