Microfabrication is a technology used to create tiny structures and devices, often at the scale of micrometers. It involves various processes such as photolithography, etching, and deposition to build intricate patterns on materials like silicon or polymers. This technique is essential in producing components for electronics, sensors, and biomedical devices. The applications of microfabrication are vast, impacting fields like semiconductor manufacturing, MEMS (Micro-Electro-Mechanical Systems), and nanotechnology. By enabling the precise control of material properties and dimensions, microfabrication plays a crucial role in advancing technology and innovation in modern science and engineering.
