Chroma ATE Inc. acquired 100 percent of the shares of Environmental Stress 
Systems, Inc. (ESS). The main product of ESS consists of thermal forcing 
systems that can reach temperatures ranging from -104°C to +175°C. This 
technology enables Chroma to grow their expertise on temperature control in 
semiconductor test equipment and meet the testing requirements of the wafer 
market for extremely low and high temperatures.

Driven by 5G, IoT (internet of things), IoV (internet of vehicles), and other 
emerging technologies, ESS has developed a cooling technology that reaches up 
to 1,500W and meet the high-power temperature control requirements for HPC 
(high-performance computing) and AI chips in advanced packaging processes. 
Research conducted by TrendForce indicates that the global satellite market 
could arrive at US$295 billion in 2022. Major countries around the world are 
deploying low Earth orbit satellites to propel the application of and 
integration between satellite and 5G communications. However, ensuring that the 
chips can still function normally in the extremely cold environment of space 
remains an important issue. ESS offers technology with high-power and extremely 
low-temperature cooling at the core, for simulating the harsh environment in 
space. In addition, biomedical test applications, such as RNA, DNA, vaccines, 
and drugs, require long-term storage of biological and pharmaceutical samples. 
ESS has rich experience in designing and manufacturing -86°C ultra-low 
temperature cold rooms for such environmentally controlled storage. This 
technology will also bring Chroma new business opportunities in the field of 
biomedical testing.

The acquisition of ESS provides Chroma with the chance to further expand into 
the market of semiconductor test applications, such as in aerospace, 
electric/self-driving vehicles, 5G, AIoT, and biomedical test equipment. Chroma 
expects that the opportunities resulting from this synergy will create a strong 
platform for future growth.
