Environmental Contribution through the Provision of Products (Eco-products)

We screen the environmental performance of new products based on our own internal regulations (TES*), and work to develop environmentally friendly products. In accordance with the new product development screening rules, we set up a product development screening committee and conduct deliberations for each product planning theme. The screening rules stipulate principles to be considered during development and design, and include the examination of environmental performance in terms of compactness and minimization of the number of parts, as well as environmental measures.

The Company recognizes its responsibility for the environmental impacts of its products over their entire life cycles. In 2016, the Technical Working Group of the CSR Committee unified the calculation standards for converting emissions to CO₂ at every stage from product manufacturing to disposal LCA. The CO₂ emissions derived through this method are set as essential evaluation items in new product development screening.  

LCA targets are set at the time of design, and LCA performance is calculated and evaluated by evaluation organizations to determine the results. By also carrying out LCA for products currently in production, we make improvements to our conventional products and conduct comparative evaluations of these with in development and new products.

Due to the nature of production equipment, products of Tokyo Seimitsu offer many hours of operation and have long service lives.
Consequently, when converted into CO₂ emissions, power consumption from usage of products accounts for a good deal of total emissions over the life cycle. This has prompted us to focus on developing and designing products for reducing environmental impact during manufacturing activities conducted by our customers.

Tokyo Seimitsu is the only manufacturer of semiconductor manufacturing equipment that possesses measurement technologies. As new value creation unique to our company, we are developing semiconductor manufacturing equipment models with built-in measurement instruments. Equipped with Optscope, a 3D white light interferometer microscope that measures surface properties, it improves the detection accuracy of shape and surface properties, contributing to improved quality and productivity.

Power semiconductors are important devices used in power converters. They are essential devices for the realization of a decarbonized society as they can reduce electricity consumption and use energy efficiently, and are used in various electronic devices including electric vehicles, railcars, refrigerators, air conditioners, wind power generation equipment, and renewable energy-relatedv equipment.

The Group has strengthened its product lineup to support next-generation power semiconductors that can withstand high voltages and high currents, lose little energy, and can be miniaturized.

In order to efficiently transmit power with precision in automobiles, airplanes, etc., components must be manufactured as designed and as specified. By measuring and managing the dimensions, shape, roundness, and surface roughness of parts, manufacturing is progressing toward the realization of decarbonization.

Based on our basic philosophy of "No Measurement, no Manufacturing," we are contributing to the improvement of performance and fuel efficiency in the automobile and aircraft industries through our measurement technologies.
