2D Silicon Interposers

IPDiA has been a pioneering Silicon interposer platform since early 2000. With more than 100 million silicon interposers delivered in various markets, IPDiA is clearly recognized as a market leader. The IPDiA interposer product offering includes a huge variety of solutions, from Basic 2D interposers to advanced 3D interposers with passive components built in the Silicon, in order to meet all your interposer requirements.

The IPDiA 2D silicon interposer is the perfect solution for applications with major size constraints. Thanks to the redistribution layer capability combined with the IPDiA Integrated Passive Device technology, most of the components required for the application can be integrated or soldered on top of the silicon interposer.
