AccuOptotec Raises $1.38M Series A to Accelerate Next-Gen Semiconductor Inspection Equipment

AccuOptotec, a South Korean semiconductor inspection equipment company, has closed a $1.38M (KRW 2 billion) Series A funding round. The round was co-led by Company K Partners and Rising S Ventures.

Founded by Professor Jeonghoon Song of the Department of Data Information and Physics at Kongju National University, AccuOptotec develops advanced semiconductor inspection systems powered by Fourier transform optics and ultra-high-speed signal processing technologies. The company’s core products include ultra-high-resolution thermal imaging equipment and non-destructive inspection systems for copper filling in glass core substrates — both critical tools for next-generation semiconductor manufacturing.

As AI semiconductors continue to drive rapid growth across the advanced packaging market, glass core substrates have emerged as a key material. However, conventional inspection methods face significant technical limitations in detecting microscopic internal defects and localized heat generation — factors that can critically impact semiconductor process yields. AccuOptotec’s solutions are designed to overcome precisely these limitations.

The company’s ultra-high-resolution thermal imaging and thermal conductivity measurement systems have drawn particular attention as next-generation inspection platforms for the non-destructive full inspection of power semiconductors and internal defects in TGV (Through Glass Via) and TSV (Through Silicon Via) structures.

“This investment reflects recognition from our investors of both the technical excellence and market potential of our next-generation non-destructive semiconductor inspection technology,” said CEO Jeonghoon Song. “We plan to accelerate the commercialization and mass-production deployment of our core equipment.”
