Supports high aspect ratio filling, copper sulfate plating additive for silicon interposers - TORYZA LCN SV.
With the advancement of semiconductor performance and functionality, packaging technologies related to chiplets that implement multiple chips with different functions on a single substrate and three-dimensional integration are gaining attention. Among these, silicon interposers with wiring formed on silicon are attracting interest because they can miniaturize the length and width of the wiring, thereby enhancing the transmission capability of high-frequency signals. Our company has developed TORYZA LCN SV as an additive for silicon interposers that supports high aspect ratio filling. TORYZA LCN SV excels in embedability into TSVs, achieving void-free and low film thickness high aspect ratio filling.
