Along with changes in social conditions, there has been proactive
investment in data centers to support the increase in data traffic due to the implementation
of AI and IoT and the advancement of support for 5G. Demand for tablets and smartphones is
also increasing due to the spread of working from home and online classes.
Furthermore, the semiconductor market is expected to develop and grow significantly in line
with increasing demand for semiconductor devices for automotive applications, such as in
electric vehicles and for autonomous driving.
It was in these market conditions that the new Naka-Marine Site factory—which is responsible
for the design, development, and manufacture of semiconductor production equipment and
analysis equipment—was constructed with the aim of expanding production capacity for core
products (primarily semiconductor manufacturing equipment) and creating a development
environment that will enable a diverse product lineup.

Establishing Highly Efficient and Stable Production
System through DX and Enhancing Development Environment of Products and Solutions
The Naka-Marine Site is a state-of-the-art smart factory which promotes DX (Digital
Transformation) by utilizing IoT. Development and production systems are enhanced by
centrally managing manufacturing data such as production progress, product performance
and production environment, and by visualizing information on each production process.
In addition, processes have been automated or fully automated (unstaffed) through the
implementation of automated parts transport and remote adjustment. Hitachi High-Tech has
established the highly efficient and stable production system to respond to the
increasing demand of the growing semiconductor-related market. In addition, to meet
customers' needs for high-precision tool-to-tool matching, Hitachi High-Tech has created
a production environment with cleanrooms that are equivalent to those used by customers
for the production of semiconductor devices. The development environment will be
strengthened and enhanced through collaboration between the designers of semiconductor
manufacturing equipment and designers of analysis equipment. This will also speed up
product development and strengthen the competitiveness of Hitachi High-Tech products.
Hitachi High-Tech will also continue the contribution to resolving the various issues
that our customers face arising from the miniaturization of semiconductor device
Contributing to the Elimination of CO2
Emissions and realization of a Decarbonized Society through Operations with the Use of
The Hitachi High-Tech Group aims to achieve zero CO2
emissions by FY2030. Work is ongoing to reduce CO2 emissions by gradually
switching to renewable energy sources for the electricity used at all Hitachi High-Tech
sites. The Naka-Marine Site has achieved zero CO2 emissions immediately upon
completion as it uses renewable energy and is equipped with solar panels, thereby
contributing toward realizing a decarbonized society. In addition to the commitment to
reducing environmental impact, environmentally conscious design (eco-design) and life-cycle
assessment have been introduced as part of the product development process. This enables the
reduction of electricity consumption in the design and development stages as well as at the
product use stage. Hitachi High-Tech also reduces CO2 emissions throughout the
value chain by increasing the number of environmentally conscious products.
