Specialist foundry SK Keyfoundry (Cheongju, South Korea), formerly Key Foundry, has announced progress in crash program of gallium nitride (GaN) power semiconductor development.

The company has said it has measured key transistor characteristics in 650V breakdown HEMTs made in GaN as part of efforts to develop a GaN power transistor within one year.

A dedicated team was formed in 2022 soon after the company was acquired by SK Hynix and the development is set to be finalized this year.

Key Foundry was spun off from Magnachip Semiconductor in September 2020, became a subsidiary of SK Hynix in August 2022. The name was changed to SK Keyfoundry at the beginning of 2024.

The company expects that the GaN 650V product will support fabless customers in markets such as fast charging adapters, LED lighting, and solar microinverters SK Keyfoundry said it plans to build a GaN portfolio of GaN HEMTs and GaN ICs spanning a range of breakdown voltages.

The GaN power semiconductor market is expected to grow at a CAGR of 33% from $500 million in 2023 to $6.4 billion in 2032, according to a market research firm Omdia. GaN power semiconductors will be used primarily in power supplies, hybrid and electric vehicles, and solar power inverters.

“We are preparing for the next generation of power semiconductors in addition to offering our competitive high-voltage BCDs,” said Derek Lee, CEO of SK Keyfoundry, in a statement. “We will also expand our power semiconductor portfolio to include not only GaN but also SiC in the future to establish ourselves as a specialized power semiconductor foundry.”
