What Park Systems AFMs Measure in Semiconductor Metrology

AFM measures a surface in three dimensions. Park Systems develops atomic force microscopes and supplies them to research institutions and industrial customers. An AFM uses interaction between its probe and the sample to measure surface shape and properties at the nanoscale. This capability differs from a disclosure of commercial volume: it describes what the instrument can measure, not how many systems a customer has installed.

Official product materials establish that the company offers both research and industrial products. Customer names and installation counts by field may have limited disclosure, so those details must not be inferred. A research application, an industrial demonstration, customer sample validation, automated-tool qualification, a purchase, installation, acceptance, and recognized revenue remain separate facts.

A semiconductor factory requires automation and repeatability. A production line must measure many wafers under consistent conditions and connect the results to process control. Resolution matters, but so do speed, variation among instruments, reliable operation, and automated transfer. An industrial system must meet this combined operating requirement; a single high-resolution image does not demonstrate performance across the production workflow.

A measurement demonstrated in a research paper is not equivalent to adoption on a mass-production line. Customer process evaluation and operational-stability testing still have to be completed. Even qualification does not identify an undisclosed process or establish a repeat installation. It establishes only the milestone supported by the company or customer evidence available to the public.

Scaling increases the number of structures that need measurement. As semiconductor structures become more three-dimensional, information about height, roughness, steps, and sidewalls becomes more important. AFM can provide complementary data that differs from information produced by optical methods or electron microscopy. The word complementary is important: it describes a potential role alongside other approaches rather than claiming exclusive supply to a process.

That technical fit does not prove an exclusive position or a particular application. Actual use must be checked through customer qualification and company order disclosures. Each application may impose different alignment, repeatability, and throughput requirements, so success in one measurement task cannot be transferred automatically to another customer, tool generation, or production step.

Acquisitions broaden technology but still require integration. Park Systems has acquired related companies and technologies to expand its metrology portfolio. An acquisition can provide access to additional products or customers, while also creating integration costs. The contract demonstrates that ownership changed under its terms; it does not demonstrate that all products were immediately combined or that cross-selling began at the same time.

Signing an acquisition, including the acquired business in consolidated results, and generating cross-sales are events on different dates. Follow-up reports are needed to evaluate revenue contribution and profitability, rather than relying only on the acquisition price. The same distinction applies to technology: adding a capability to the portfolio does not establish customer qualification, orders, shipment, or revenue for every combined offering.

The May Filing Quantifies AFM's Current Commercial Position. Park Systems' quarterly report filed on May 14, 2026 identifies advanced metrology equipment, including atomic force microscopes, as its manufacturing and sales business and consolidates eight unlisted subsidiaries. Research and industrial AFMs are existing commercial product families, not future concepts.

The filing showed first-quarter consolidated revenue of about KRW 39.4 billion and operating profit of about KRW 2.1 billion. Product mix between research and industrial systems and the timing of customer installations influence profitability, so revenue growth alone does not establish expansion across semiconductor production lines.

The next evidence is industrial-system revenue share, backlog, clustered installation and delivery dates, and repeat orders. Adoption by a particular semiconductor production line should be cited only when the company discloses the installation.

Order and delivery timing can create seasonality. Industrial-equipment sales can cluster in particular quarters because of customer budgets and installation schedules. The relative contribution of research and industrial systems can also affect profitability. A strong or weak quarter should therefore be read through product mix and delivery or acceptance timing, rather than treated as a constant run rate for semiconductor AFM demand.

Industrial revenue, order backlog, geographic revenue, research and development spending, and contributions from acquired businesses are the useful checks. Semiconductor expansion is verified through actual equipment installation and repeat orders. Technical suitability starts the sequence, while customer validation, qualification, purchase, installation, acceptance, and reported sales supply the successive commercial evidence.

A comparison of AFM applications. If ten research AFMs sell for KRW 200 million each while three production-line systems sell for KRW 800 million each, production revenue of KRW 2.4 billion exceeds research revenue of KRW 2 billion despite the lower unit count.

If the production system remains in pilot evaluation and has neither acceptance nor a service contract, do not classify it as mass-production metrology revenue.

A table separating unit count, price, and recurring service revenue for research and production systems reveals the expansion of semiconductor metrology.
