Unisem is showing strong performance in early trading.
As of 9:03 a.m. on August 11, Unisem was trading at 8,240 won, up 7.15% (550 won) from the previous trading day.
Investor sentiment appears to have been boosted by news that the company has succeeded in developing an eco-friendly carbon dioxide chiller for semiconductor processes and is preparing to supply demo equipment to a global foundry company based in Taiwan.
Chillers are essential equipment for precisely controlling temperatures in various semiconductor manufacturing processes such as cleaning, deposition, and etching, and they play a key role in process stability and yield improvement. According to the company, once the performance and stability of the CO2 chiller are verified, it will become the world's first eco-friendly chiller equipment to be introduced into semiconductor processes.
