Exclusive delivery of low-temperature,

●A Korean semiconductor sub-director with TSMC as its customer



* * HPSP
- Exclusive delivery of low-temperature, high-pressure hydrogen annealing equipment
- 70% of non-memory sales and 30% of TSMC sales
- It is expected to be completed in the first half of the year as it is undergoing a quality test of high-pressure wet oxide film equipment (HPO) at TSMC. The equipment will be used to form an oxide film under low-temperature and high-pressure environment and will be applied to ultra-fine processes with more than 3 nanometers

* Dongjin Semichem
- Promotion of PR supply for EUV
- Confirmation of supply of sulfuric acid for wafer cleaning to TSMC after establishment of local plant in Texas, U.S

* Wonik QnC
- Targeted to expand to 30% by 2028 with 15% share of quartzware in TSMC
- TSMC's sales exceed 5% and non-memory sales 20% (TSMC, Samsung Electronics, Intel)
- The proportion of legacy process sales under 40 nanometers is 60%, and the proportion of sales of front-end process will increase in the future due to the quality test of 3 nanos products at a new plant in Korea
