AP Systems takes stake in optics inspection firm SDOptics for chip packaging push
What's the deal? AP SystemsDealroom has a profile for this one. Try Dealroom → is acquiring a stake in SDOptics, a Korean maker of ultra-precision optical inspection solutions, the company said on October 28. AP Systems is subscribing to convertible preferred shares through a third-party allotment paid-in capital increase. The deal value was not disclosed.
What each side brings: AP Systems makes semiconductor and display process equipment. SDOptics, founded in 2010, commercialised a Micro-Electro-Mechanical Systems (MEMS) based "mirror array lens" technology (MALS) that shifts focus in real time without mechanical vibration, controlling a micro-mirror array at 12,000Hz.
What's the endgame? The two plan to jointly develop metrology and inspection equipment for advanced packaging, targeting high-bandwidth memory (HBM), fan-out panel-level packaging, and through-glass vias (TGV) on glass substrates. AP Systems intends to fit SDOptics' MALS-based 3D line-scan module into its own tools to measure surface shape, step height, and residue in real time.
Why now? Demand for advanced packaging inspection is starting to convert into equipment orders, with rivals such as Jarvis and InnometryDealroom has a profile for this one. Try Dealroom → recently disclosing new TGV contracts and customer wins. AP Systems said first-half operating profit rose 166.5% year on year, with record new semiconductor orders — framing the deal as an effort to add inspection capability to a growing equipment business.
SDOptics already supplies inspection modules to TGV, advanced packaging, and display makers, and its MALS technology has been adopted in ZEISS microscope systems.
What AP Systems says: The company said it will "maximise the added value of our main equipment" through the tie-up and "secure a powerful new growth driver in the next-generation semiconductor inspection market."
What could go wrong? The investment size, stake, and timelines for customer qualification and commercialisation have not been disclosed, leaving it unclear whether the market opportunity will translate into earnings.
The signal: The deal reflects a broader move among Korean equipment makers to build inspection and metrology capability in-house as advanced packaging — HBM, panel-level packaging, and glass substrates — shifts from promise to purchase orders.
