The benchmark Korea Composite Stock Price Index (KOSPI) rose 97.12 points, or 1.4 percent, to 7,051.64.

Overnight, the Philadelphia semiconductor index increased 1.3 percent despite declines on Wall Street's three main indexes amid escalating tensions in the Middle East.

Market bellwether Samsung Electronics was flat at 269,500 won, while its chip rival SK hynix jumped 3.51 percent to 1.86 million won.

Samsung Electro-Mechanics, an electronics component affiliate of Samsung Electronics, gained 2.48 percent to 1.4 million won.

Leading battery maker LG Energy Solution jumped 6.46 percent to 371,000 won, while its smaller rival Samsung SDI surged 8.3 percent to 574,000 won.

Hanwha Ocean went up 2.32 percent to 88,100 won after the shipbuilder said it had been selected as the preferred bidder for a Royal Thai Navy frigate project worth about US$500 million.

The Korean won was quoted at 1,336.1 won per U.S. dollar as of 3:30 p.m., up 6.7 won from the previous stock trading session's close.
