Thin film deposition in semiconductors is a critical process used to create ultra-thin layers of material, typically less than 1000 nanometers thick, on a substrate. This technique is essential for manufacturing semiconductor devices, integrated circuits, and micro/nano devices. The process involves depositing materials in a vacuum chamber using methods such as thermal evaporation, sputtering, ion beam deposition, or chemical vapor deposition. Thin film deposition enables precise control over material properties, making it indispensable for applications in electronics, solar panels, optical devices, and nanotechnology. Its role in sustainable technologies and modern electronics underscores its importance in advancing technological innovation.
