We are WGS, a semiconductor process diagnosis and
machine vision specialist company.

The annual loss of semiconductor manufacturing accounts for 10% of the global semiconductor market,
but the inspection/measurement/diagnosis market that can reduce the loss accounts for only 0.8% of the global
semiconductor market, and the domestic process diagnosis market is currently 1.8%, which is a negligible level, but it is a
market with thousands and tens of thousands of % potential if it responds to the global semiconductor market. In this regard,
we identified the current problems of the process diagnosis system, confirmed the need for real-time diagnosis and analysis,
We established WGS Co., Ltd. on September 22, 2020 by presenting real-time diagnosis solutions using RF sensors and
optical sensors and inspection solutions using machine vision and 2D and 3D technologies, which are inspection/diagnosis
solutions in semiconductor processes.

With WGS’s solutions, we can increase semiconductor yield and reduce manufacturing losses, which will enable us to
compete in the global market as well as domestically, and thus increase the value of our customers and grow our value as
well. We are WJS, a company that can coexist with each other.(Based on data as of 2022)
