SKC Co., a South Korean materials company, is acquiring a 12 percent stake in Chipletz Inc. (Austin, Texas), a fabless substrate startup, according to the Yonhap news agency.
SKC is a subsidiary of SK Group and announced the deal through a press release but did not disclose the size of the investment. The move is in support of an expansion from battery materials towards semiconductors by SKC.
Chipletz started off as an in-house venture of AMD before being spun out in 2021. It is developing a technology called Smart Substrate. By supporting die-to-die interconnect, I/O and multiple voltage domains within the substrate Chipletz wants to support the integration of almost any die from any manufacturer.
SKC already has a majority stake in Absolics Inc. (Covington, Georgia), which makes glass-cored semiconductor substrates. SKC owns 80.6 percent of Absolics and has invested US$240 million in a 12,000-square-meter factory with the goal of starting mass production of substrates in the second half of 2024.
