Camtek received a USD 31 million multi-system order from a leading OSAT on March 30, 2026, with the systems intended for CoWoS-like advanced packaging applications. The order highlights the growing need for inspection and process-control capabilities as semiconductor manufacturers handle more complex 2.5D and 3D packages.

The development comes as demand for advanced packaging process control software expands from USD 1.3 billion in 2026 to USD 5.5 billion by 2036, according to Fact.MR. The market is projected to advance at a 15.3% CAGR between 2026 and 2036, supported by tighter package-release checks, growing 2.5D/3D IC adoption, and greater demand for traceable yield decisions.

Why are advanced packaging fabs putting more emphasis on process control?

Advanced packaging brings more process steps, inspection points, and data into a single package flow. For fabs and OSATs, the challenge is not simply detecting a defect but connecting inspection results with yield records, rework decisions, and final lot-release evidence.

That requirement is strengthening the case for software that can bring inspection analytics, advanced process control (APC), yield management, and AI-based defect classification into a controlled workflow. Camtek's March 2026 order and Onto Innovation's qualification of its Dragonfly G5 for 2.5D advanced-packaging applications in April 2026 provide commercial signals of rising inspection requirements alongside this software demand.

The connection between packaging complexity and software adoption is becoming particularly important for 2.5D/3D IC production. As more dies, interposers, bonding operations, and inspection results must be reviewed together, process-control systems have a larger role in determining whether a package lot proceeds, is reworked, or is held.

Yield management and 2.5D/3D IC lead the market

Yield management is projected to account for 31.0% of the market by capability in 2026. Packaging fabs are prioritizing software that can maintain records of excursions, bin maps, review holds, and release decisions.

Meanwhile, 2.5D/3D IC is expected to represent 34.0% of demand by packaging type in 2026. Chiplet-based packages require connected data across interposer, bonding, inspection, and related process stages, increasing the value of software that can maintain traceability across the production flow.

On-premise/fab deployment is also expected to remain dominant, accounting for 62.0% share in 2026. Fabs continue to treat recipe history, inspection records, and process information as sensitive production assets, making local deployment attractive where security and integration requirements are strict.

What's driving near-term demand?

Package yield management is identified as the strongest near-term demand driver, with an estimated +3.6% impact on CAGR. The report links this trend to the need for traceable release decisions and notes that NIST reported USD 1.4 billion in finalized CHIPS NAPMP awards in January 2025, including USD 1.1 billion for advanced-packaging prototyping and piloting capabilities.

2.5D/3D IC process complexity is another major near-term factor, with an estimated +3.1% impact on CAGR. The report cites Synopsys' April 2025 statement that its 3DIC Compiler supports CoWoS with 5.5x reticle interposer sizes, illustrating the scale and complexity of package designs that process-control workflows increasingly need to accommodate.

Inspection analytics integration is expected to contribute a further +2.4% impact on CAGR. The report cites Onto Innovation's April 2026 qualification of Dragonfly G5 for 2.5D advanced-packaging applications as evidence of increasing inspection requirements.

At the same time, fab data governance remains a restraint, with an estimated -1.5% impact on CAGR. Security reviews can delay software pilots when package data contains customer designs and detailed process histories.

Taiwan and South Korea show the fastest country-level growth

Taiwan is projected to record a 17.1% CAGR from 2026 to 2036, the highest among the countries covered in the report. South Korea follows closely at 17.0%, while the United States is projected to grow at 16.2%.

Taiwan's position reflects its deep semiconductor manufacturing base, expanding package-process monitoring requirements, and growing use of 2.5D/3D IC packaging. South Korea's growth is tied to memory production, HBM packaging, and rising inspection workloads.

The United States is projected to reach 16.2% CAGR, supported by advanced-packaging investment and demand for secure fab analytics. The Netherlands, Germany, and Japan are forecast to grow at 15.7%, 15.5%, and 15.0%, respectively.

Analyst Perspective

Shambhu Nath Jha, Principal Consultant at Fact.MR, states:

"Advanced packaging process control software is drawing attention because defect context now decides whether expensive package lots are released or held."

He adds that production acceptance is expected to increasingly depend on software's ability to connect inspection signals, yield rules, and traceable review paths, while suppliers need to combine secure fab deployment, model governance, and package-specific analytics.
