Recently, Gaize Precision Technology (Suzhou) Co., Ltd. (hereinafter referred to as "Gaize Technology") disclosed on its official WeChat account that the company has taken over the entire Suzhou plant of Japanese optical giant USHIO, and that once the plant upgrade and renovation are completed, this site will become Gaize Technology's core industrial carrier.

What kind of optical company is Gaize Technology? Why did it acquire a Japanese factory at this particular juncture?

Gaize Technology was founded in 2021 and completed nearly 100 million yuan in Series B industrial financing in 2025. According to company disclosures, its core optical components and metrology systems are developed in-house, and products such as FTIR film thickness metrology have passed validation by multiple wafer fabs and Fab customers and are shipping in volume. In the first three quarters of 2025, orders had doubled compared with the full previous year, and in early 2026 film thickness metrology equipment achieved volume deliveries in Europe. Technical feasibility and customer validation have already been completed; what is truly constraining its next step is production capacity.

This is precisely where the core value of taking over the entire plant lies. USHIO Suzhou was established in 2004 and has long been engaged in the R&D and production of optoelectronic components and precision instrument equipment. Its plant was built to Japanese precision manufacturing standards, with cleanrooms, specialized load-bearing infrastructure, power support, and environmental systems all aligned with the requirements of high-end optical manufacturing. Directly acquiring a plant built to Japanese standards, including its hardware and infrastructure, means Gaize Technology can compress the time needed for infrastructure and hardware compliance to the shortest possible.

According to the plan disclosed by the company, the plant will host three simultaneously implemented segments: a mass production center for the full series of wafer optical metrology equipment, a high-end optical R&D and calibration center, and an overseas customer prototype validation center, respectively addressing scalable delivery, connecting the full in-house development chain from design to precision, and moving debugging and pre-delivery work closer to customers to build a closed-loop global service system.

However, it should be noted that what Gaize Technology has taken over is a set of plant hardware and infrastructure built to Japanese precision manufacturing standards, not a ready-made team of skilled workers and on-site management. Whether the cleanrooms can meet the specific environmental requirements of metrology equipment, whether the power systems can remain stable under Gaize's process conditions, how the production line should be adapted, and how personnel should be organized all require renewed validation and adjustment.

Taking over an entire plant compresses the time for infrastructure and hardware compliance; what it does not automatically compress is the time for process stabilization, personnel development, production line ramp-up, and repeated customer-side validation. The latter is precisely the real bottleneck in moving metrology equipment from "being able to make it" to "being able to deliver it stably, in volume, and with service support."

Of course, taking over a plant does not equal automatically obtaining production capacity. Between Japanese precision manufacturing standards and the operating systems of a domestic equipment company, there are real integration costs in management convergence, production line adaptation, and personnel organization. The plant's hardware conditions can be inherited, but the capability to continuously and stably produce high-precision metrology equipment still needs to be proven by Gaize Technology through order delivery.

This leap by Gaize offers a path worth observing for domestic semiconductor equipment companies: after the initial "0 to 1" of technological breakthrough has been largely completed, using M&A of mature manufacturing assets to accelerate the "1 to N" realization of production capacity may fit the current industrial rhythm better than waiting through cycles on self-built production lines.

The domestic substitution of optical metrology is moving from parameter catch-up in the laboratory into a delivery race on the factory floor. And the final outcome of this race depends on who can truly build up the capability for stable delivery inside the plant.
