Samsung Electronics Is Working On A New Chip Packaging Material: Glass Interposers

Samsung Electronics' Device Solutions (DS) division has started developing glass interposers as a next-generation packaging material. The goal isn't just to replace expensive silicon interposers – it's also about boosting chip performance.

According to reports, Samsung recently received a joint proposal from Chemtronics (an Australian materials company) and Philoptics (a South Korean equipment maker) to develop glass interposers. Sources suggest Samsung is considering having these companies produce glass interposers using glass from Corning.

At the same time, Samsung's subsidiary Samsung Electro-Mechanics is working on glass carriers – also known as glass substrates – with plans to start mass production the year after next. Having these two R&D efforts running in parallel is sparking some healthy internal competition. Samsung seems to be betting that this will push both productivity and innovation.

A quick explainer: an interposer is what connects a semiconductor substrate to the chip. Right now, interposers are made from expensive silicon, which is a big reason why high-performance chips cost so much. Switch to glass, and production costs drop significantly. Glass also handles heat and shock well, and it simplifies the micro-circuit manufacturing process. That's why a lot of people see glass interposers as a potential game-changer – something that could take semiconductor competitiveness to a whole new level.

By developing glass interposers independently, rather than relying solely on Samsung Electro-Mechanics' glass substrates, Samsung Electronics seems to be playing a smart strategy: using internal competition to get the best possible results. It also suggests that the pressure to improve performance is real – serious enough that Samsung wants a state of "creative tension" across its entire supply chain.
