➀ KitGuru visited the MSI Shenzhen factory to witness the production of the first Z890 Tomahawk motherboards; ➁ The factory has implemented automation and AI to reduce the workforce to 3,000 from 12,000 in 2001; ➂ The production process includes soldering, automated optical inspection, and physical and electrical tests.

➀ Overview of semiconductor manufacturing processes, divided into front-end (wafer processing) and back-end (assembly and testing) stages. ➁ Detailed steps in the front-end process include silicon wafer input, cleaning, film deposition, photolithography, and impurity diffusion. ➂ Back-end processes involve chip assembly, packaging, and final testing for quality assurance. ➃ Advanced exposure technologies, such as stepper systems and immersion lithography, are crucial for achieving smaller transistor sizes. ➄ Emerging technologies like EUV lithography promise further miniaturization and efficiency improvements in semiconductor manufacturing.

1. The iPhone SE 4 may share a similar rear chassis manufacturing process with the iPhone 16. 2. This could mean changes in camera layout and potential adjustments to the optics. 3. The iPhone SE 4 is expected to launch in 2025.
