Samsung has restarted work on its SiC foundry push, a move that could ripple far beyond power semiconductors and into everything from EVs to your next Galaxy device.

Rewind to 2023, Samsung had SiC on the table alongside its GaN ambitions, but the broader chip slump and a pressing need to stabilize its memory business forced a slowdown.

Recent talks with materials suppliers and equipment vendors suggest the company is no longer testing the waters. It is lining up a supply chain; there are even early conversations around tool capacity, which usually come later in the cycle.

This looks like a shift from “explore” to “prepare.” The target is 2028 for mass production, which sounds distant, but in semiconductor terms, it is almost aggressive, especially for a segment where process maturity still lags traditional silicon.

Unlike advanced logic, where 12-inch dominates, SiC is still transitioning from 6-inch to 8-inch wafers. That makes 8-inch the cutting edge in this niche. For Samsung, it is a rare alignment of old infrastructure and new demand.

SiC handles higher voltages and temperatures with less energy loss. That is why it is showing up in EV drivetrains, fast chargers, solar inverters, and increasingly, data center power systems tied to AI workloads.

SiC will not sit inside an application processor anytime soon, but it can influence charging circuits, power management ICs, and even infrastructure behind cloud services that Galaxy devices rely on.
