Samsung Electro-Mechanics and LG Innotek advance Intel's EMIB-T substrate supply

According to a report by ZDNet Korea on the 9th, Samsung Electro-Mechanics and LG Innotek are advancing into the Intel EMIB-T packaging substrate supply chain, with related product development and testing already underway. EMIB connects chips with small silicon bridges, which Intel previously used mainly for its own chips; the improved EMIB-T is expanding external sales. The next-generation AI accelerator TPU that Google plans to launch in the second half of next year will be the first to use EMIB-T. EMIB-T inserts silicon vias for power transmission within the silicon bridge.

Insiders say that Samsung Electro-Mechanics has developed EMIB substrate samples over the years and is currently advancing EMIB-T supply based on the 2.1D packaging substrate concept. Recently, LG Innotek delivered EMIB-T packaging substrates to SK Hynix for sample testing, and both parties are installing HBM on the substrate to evaluate product characteristics.

Currently, EMIB-T packaging substrates are supplied by Japan's Ibiden, Shinkawa Electric, Taiwan's Xinxing Electronics, and Austria's AT&S. Ibiden has decided to utilize idle factories to construct a dedicated production line for Intel's EMIB-T substrates, with an investment scale of about 20 trillion Korean won, and it is reported that they have already received advance payments from Google, Amazon, Intel, and others.
