On June 22, United Microelectronics (UMC) rose 7.93% in pre-market trading, trading at $26.06/share, with turnover of $194,000, extending its recent strong rebound momentum.

On the news front, Intel and UMC have reached a collaboration to jointly develop 3nm and 12nm process technologies, with production lines to be located at Intel's Arizona facility. The 12nm process is expected to begin mass production and contribute revenue next year, while the 3nm process targets performance on par with TSMC's standards. Notably, UMC can enter the advanced process segment without significant capital expenditure. Additionally, UMC's embedded Deep Trench Capacitor (DTC) technology has successfully entered Qualcomm's supply chain and begun shipments. These developments are layered on top of Q1 net profit surging 108% year-over-year to NT$16.17 billion and selective price hikes of approximately 10% planned for the second half.

Within the Semiconductor sector, the broader recovery continues with Intel up 4.25%, Micron Technology up 3.06%, Marvell Technology up 2.16%, and Advanced Micro Devices up 0.31%.
