The company said Friday it submitted a preliminary listing application to the Korea Exchange (KRX), with Samsung Securities serving as the lead underwriter.
Revenue rose to 92.3 billion won ($64.7 million) last year from 59.5 billion won a year earlier, while operating profit jumped to 7.8 billion won from 1.1 billion won, as demand from global semiconductor equipment makers increased.
Founded in 1997, Dongwon Parts manufactures parts used in semiconductor equipment for etching, deposition and cleaning — processes used to shape, build and clean the thin layers that make up semiconductor chips.
Its main products include showerheads and chamber parts used inside chipmaking equipment. Showerheads spread gases evenly across semiconductor wafers during production, while chamber parts form part of the enclosed space where chips are processed. The company has not unveiled the names of its core clients.
Using technology that drills tiny holes with high precision, Dongwon Parts supplies parts to major U.S. chip equipment makers, including Lam Research and Applied Materials. Direct exports and sales to global equipment makers account for 51 percent of its revenue.
To support those customers, it handles most of the manufacturing process itself, from preparing and machining materials to assembling and inspecting finished products. Keeping these steps in-house allows the company to supply assembled modules and develop prototypes more quickly.
The company plans to follow the standard listing process, backed by its earnings and global customer base. It will not use a special listing track that allows promising technology companies to go public even if they do not yet meet standard financial requirements.
Cho Deok-hyung, CEO of the company, said rising investment in equipment used to produce AI chips, high-bandwidth memory (HBM) and more advanced chip packages is creating new opportunities for the company.
“The KOSDAQ listing will help us strengthen our semiconductor parts business and expand into new industries using metal 3D printing technology,” he added.
