CTO Message

Message from the CTO

I have been engaged in technology development at the forefront of the semiconductor test field for more than 30 years.
In particular, I have addressed challenges related to test technology, failure analysis, quality improvement, and test cost optimization in wafer test (WT) and final test (FT) processes, building practical solutions that work on actual production sites.

Today, by combining knowledge accumulated over many years with advanced AI-based data analysis technologies, we are developing tools that create the following combined value.

  • Significant reduction of test and manufacturing costs
  • Continuous yield improvement
  • Shorter turnaround time (TAT)
  • Reduction of loss-related costs
  • Further enhancement of product quality

Our goal is to provide analysis and tools designed for real manufacturing environments and deliver immediate value.
We sincerely hope to build win-win relationships by solving real customer challenges together and contributing to next-generation manufacturing.
