The ingot is sliced using diamond saws into ultra-thin wafers.
Fabs use advanced Air Handling Units (AHUs) and High-Efficiency Particulate Air (HEPA) filters to maintain strict cleanliness standards, categorized by ISO classes. Workers wear specialized suits ("bunny suits") to prevent human skin, hair, and dust from contaminating the process. Ultra-short wavelength light passes through a quartz mask
Removing unwanted material to define circuit patterns.
The semiconductor industry is defined by , which predicted that the number of transistors on a chip would double approximately every two years. Van Zant’s editions have tracked this progress. Early Editions: Focused on micron-level technology. Fabs use advanced Air Handling Units (AHUs) and

: Uses liquid chemical acids. It is isotropic, meaning it etches in all directions, which can undercut the mask pattern.
