Russia challenges chip equipment with technology to cut wafer exposure from two weeks to five minutes

A Russian startup has unveiled multi-cathode electron-beam lithography technology that uses multiple electron beams at once to speed up semiconductor exposure. Developers said a silicon wafer could be exposed in about 5 to 7 minutes, compared with 1 to 2 weeks using a single beam. They said they have verified operation of a multi-cathode electron source, not a complete tool. Experts said industrial use would require further development, stable control and funding.

Samsung Electronics, SK Hynix slump puts bitcoin on edge; what markets are watching

A sharp fall in shares of Samsung Electronics and SK Hynix is emerging as an early risk signal for bitcoin, as the cryptocurrency has recently shown a high correlation with AI-linked tech stocks. The selloff pushed South Korea’s KOSPI to a three-month low and spread to U.S.-listed SK Hynix shares and the Nasdaq 100. Markets are watching upcoming earnings and signs of whether AI investment expectations are weakening or risk aversion is deepening.

Korean stocks may rebound after Black Tuesday; brokers see leaders regaining strength

South Korean shares plunged more than 10 percent in a day, prompting brokerage analysts to flag a higher chance of a short-term rebound after an outsized drop. They said the selloff likely reflected position unwinds in semiconductors and leverage products amid thin liquidity rather than a new recession signal. Analysts cautioned against reading an initial bounce as a trend reversal, urging investors to watch foreign flows, the won-dollar rate and corporate earnings.
