Lasertec proactively takes on the growing challenge of global warming and other environmental issues as part of its efforts to contribute to solving social issues through business execution.

Mid- to long-term vision

We are striving to make the following vision come true in the mid- to long-term:

  • We contribute to increasing the energy efficiency of electronics and industrial equipment around the world with the development of innovative inspection and measurement tools that are necessary for semiconductors, FPDs and others to achieve higher performance, higher production yields, and lower energy consumption.
  • We contribute to facilitating the commercial application of next-generation power semiconductors using SiC and GaN and to enhancing the performance and safety of lithium-ion and other rechargeable batteries, which are crucial for making electric vehicles more reliable and affordable.
  • We anticipate mid- to long-term market growth for our products driven by an increase in demand for semiconductors with the advent of new applications such as 5G, AI, IoT, and autonomous driving, but we prevent it from causing a proportional increase in GHG emissions from our production and sales promotion activities by managing to reduce emissions per revenue effectively.
  • We contribute to the realization of a sustainable society throughout our supply chain in cooperation with our manufacturing subcontractors and suppliers.
