Corporate Sustainability

Enabling a smarter, safer, and more connected future.



Cohu is focused on making a positive contribution to society by creating products that enable healthier lifestyles, greater longevity, and a more habitable planet. Cohu has evaluated its sustainability initiatives under SASB Standards, as amended by the International Sustainability Standards Board (ISSB) of the IFRS Foundation.


“Sustainability is not a standalone initiative – it is embedded in how we design, build, and support the solutions that power the world’s most advanced technologies. In 2025, we delivered the largest emissions reduction in our history while continuing to advance the technologies that make semiconductor manufacturing more efficient, more reliable, and more sustainable.

Membership Organizations


SBTi

Cohu has committed to set near-term company-wide emission reductions in line with climate science with the Science Based Targets initiative (SBTi).

The SBTi is a collaboration between CDP, the United Nations Global Compact, World Resources Institute (WRI) and the World Wide Fund for Nature (WWF), and one of the We Mean Business Coalition.

The SBTi defines and promotes best practice in science-based target setting, offers resources and guidance to reduce barriers to adoption, and independently assesses and approves companies’ targets.



SBER

Cohu has joined the Sustainable Business & Enterprise Roundtable (SBER), with the goal of reviewing strategies to reduce GHG emissions at principal operating sites and investigating renewable electricity energy sources.

The SBER provides strategic advisory and support services in enterprise decarbonization and is trusted by scores of the world’s leading companies. The Sustainability Roundtable helps executives to set goals, drive progress, and report results as they lead their organizations toward more sustainable, high performance — all to help align business with life.

Reducing Global Carbon Footprint

We encourage and partner with our employees to ensure we live on a healthy Earth. We promote recycling, the use of reusable water bottles, and a bike-to-work program. We have installed energy saving technology for lighting and heating, source green electricity and self-produce energy by photovoltaic system. Cohu has invested in LED lighting conversion projects at our global sites. A total of five sites have ~100% LED lighting, including two of our largest manufacturing facilities – a 99K sq. ft. Melaka, Malaysia and a 92K sq. ft. Laguna, Philippines.

Energy-Efficient Manufacturing

Reduced energy usage by 4% year-over-year


In 2025, total energy usage decreased by 4% year-over-year and increased our share of renewable electricity from 26% to 63%.

In Singapore, we transitioned our 13K sq. ft. manufacturing facility to 100% renewable electricity.

In Philippines, we transitioned our 92K sq. ft. Laguna manufacturing facility to renewable electricity.

In Malaysia, our 99K sq. ft. Melaka manufacturing facility was convered to renewable energy capped at 253K kWh per month.

At our Osaka, Japan, 67 sq. ft. manufacturing 100% our electricity is being derived from renewable sources.

Our Kolbermoor, Germany, innovation center is a certified “KfW Efficiency House 70”, and produced energy by a photovoltaic system and heat pumps on the roof. IN 2024, we achieved 100% of our electricity supply being derived from renewable sources.

At our Lincoln, Rhode Island manufacturing facility, we have invested in collaborative robotic assembly improving operational efficiency and workplace safety. The robots also work with our employees to automate repetitive work.

Outstanding Green Subscriber Award

Avoiding Scrap Material Waste


Krypton™ Cohu’s next generation inspection metrology system’s unique race-track architecture enables higher throughput and productivity. The system is factory automation ready with Autonomous Mobile Robot hardware and communications interface.

AI Inspection™ utilizes proprietary deep learning and neural network technologies to improve inspection yield without compromising quality. Real-time computation that enables semiconductor manufacturers to improve visual inspection accuracy at production speeds.

We believe that the product offers significant sustainability benefits by reducing scrap material. For example, in a typical large back-end semiconductor manufacturing facility, annual scrap avoidance could be in excess of 200M semiconductor devices.

 

Optimizing Temperature Control


Cohu’s unique T-Core™ active thermal control (ATC) technology dynamically removes heat from devices during testing to optimize temperature control, minimizing test time and yield loss. Cohu’s patent-pending Volta-Flux™ high-power density solution enables efficient heat dissipation from the top and bottom surface of the die under test for high-voltage and high-current applications.

The Diamondx Air-Cooled Universal Test Platform.

Compact Low-Power Technology


Cohu’s Diamondx™ product line was designed to deliver cost reductions in both capital and operating costs. Our air-cooled architecture and instruments do not require compressed air or chilled water. Diamondx™ consumes 2.8 kVA of electrical power, ~75% less power is required versus a comparable liquid-cooled test system. Diamondx™ includes compact low-power (CLP) technology which uses less energy to operate. Cohu’s CLP technology greatly reduces greenhouse gas emissions.

Extending the Life of the Platform


Our Sense+™ platform was designed to be an all-in-one system for testing, calibration, final inspection, and packaging of MEMS Sensor devices, delivering the full backend process in one tool creating less work-in-progress and a better cost of test.

Its architecture isolates the test of MEMS from outside noise and vibration, significantly increasing test accuracy and daily output. The system can operate on a standard noisy test floor, eliminating customers’ need for additional anechoic rooms or chambers on the production floor resulting in energy savings and a reduced footprint.

Sense+™ also provides customers the flexibility to reconfigure the system in the field to test different sensors, and it can be mechanically de-coupled from the production system for use as a standalone unit for engineering or low-volume manufacturing, thereby extending the useful life of the platform.
