Thin-film technology in semiconductors refers to the process of creating extremely thin layers of materials, often just a few micrometers thick, to form functional components like transistors, solar cells, or sensors. These thin layers are deposited onto substrates such as silicon wafers or flexible materials, enabling the production of compact, lightweight, and highly efficient semiconductor devices. This technology is widely used in applications ranging from consumer electronics (e.g., smartphones, OLED displays) to renewable energy (e.g., solar panels) and advanced systems like MEMS and biomedical devices. Its ability to reduce space, weight, and wiring errors makes it a cornerstone of modern electronics and semiconductor innovation.
