With the semiconductor cycle strong amid the artificial intelligence (AI) industry boom, shares of related names also jumped on expectations that glass substrate supply will kick into full gear. A glass substrate is a semiconductor substrate made using glass instead of conventional plastic, cutting power consumption by half and significantly improving data throughput.
Chemtronics shares traded at 41,850 won on the KOSDAQ market. The stock rose 19.74% (6,900 won) from the previous session. It even hit the upper limit during intraday trading (the top band of the daily price limit), pushing the price up to 45,400 won. It was an all-time high. At the same time, Philoptics also jumped more than 20%, nearing the record high set in Feb. this year.
Investor sentiment appeared to be stoked as an outlook emerged that glass substrate supply will begin in earnest, centered on U.S. big tech. Philoptics is developing and supplying core process equipment needed for glass substrate manufacturing. Chemtronics has been strengthening cooperation in the glass substrate business with Samsung Electro-Mechanics.
