On the news front, the semiconductor sector staged a strong rebound following a prior session plunge of over 6% in the Philadelphia Semiconductor Index. Sector peers including Micron Technology gained 7.52%, Intel rose 3.91%, and AMD climbed 2.93%, driving a systematic recovery that supported UMC's oversold bounce.

Additionally, market reports indicate Intel and United Microelectronics will jointly develop 3nm and 12nm process technologies, with production lines to be established at Intel's Arizona facility. UMC has not confirmed the partnership, stating it does not comment on speculative reports. Meanwhile, nearly 20 global analog and power semiconductor companies initiated a new round of price increases on July 1, reinforcing expectations of an industry upturn and further boosting market sentiment.
