[Participated in the 2019 Semincon Korea]
AUROS Technology is the only South Korean company that specializes in overlay measurement equipment. Almost half of the overlay equipment used in large memory manufacturers of Korea is made by AUROS Technology.
Last year’s sales more than doubled the total of the previous year. AUROS Technology had sales of 10.87 billion KRW in 2017. An official from the company stated ‘We are aiming to grow our sales by 1.5 to 2 times every year.” With the leap they made in 2018, AUROS Technology had successfully built a foundation for entering the Chinese, Japanese market in the near future.
Until being processed, semiconductor wafers go through a repeated process of stamping patterns, covering with materials, cutting, and washing. Each wafer must go through this repeated process for at least a few hundred times over 2~3 months to be certified as a ‘processed wafer.’
An overlay measuring equipment is a piece of equipment that checks whether the materials are correctly aligned on the top of the wafers. It checks by applying a ray of light to the wafer, then analyzing the reflected light. Whenever a new layer of material is stacked, this equipment is used to detect errors in nanometers, then correcting the location of the lithography equipment accordingly. It is very important to have a high resolution, accuracy, speed, and a lamp with a long lifespan.
According to industry experts, the overall size of the overlay measuring equipment market is estimated to be between 400~450 billion KRW worldwide. Currently, a U.S measurement equipment company owns more than 60~70% of the market share, enjoying a monopoly position in the market. The other 30~40% is held by a Dutch lithography equipment company.
Many experts stated that it is not easy to simply jump into this market and make a profit.
Although many skeptics believed that it was a foolish move, AUROS Technology has constantly invested in developing their own technology through R&D investment since its establishment in 2009. As a result, they are currently actively participating in discussions on supplying equipment for new clients by utilizing their unique, differentiated technology and business strategies.
AUROS Technology has recently received much feedback from their clients that their equipment is showing superior accuracy and speed in overlay measurement, compared to other competitors. They were also chosen as one of SK Hynix’s ‘Technology Innovation Companies’ in April 2017.
Facing the new era of 4th Industrial Revolution, AUROS Technology is also preparing to enter the market of overlay equipment for packaging, TSV, automobiles, and MEMS.
