🌐 Overview A silicon wafer is a thin, circular slice of crystalline silicon used as the foundational substrate for the fabrication of semiconductor devices. These wafers serve as the base material upon which integrated circuits, microprocessors, memory chips, and sensors are constructed using advanced microfabrication techniques. Silicon wafers are central to modern electronics and are […]
🌐 Overview Photolithography is a microfabrication process used to transfer extremely precise patterns onto a surface, most commonly a silicon wafer used in semiconductor manufacturing. The technique relies on light-sensitive chemical coatings and optical exposure to create patterns that define electronic circuits, transistors, and microscopic structures. Photolithography is the foundational technology that enables the fabrication
