Thin Film & Wafers

A thin film wafer is a layer of material that ranges from fractions of a nanometer (monolayer) to several micrometers in thickness. Thin films are created through a variety of deposition techniques, such as physical vapor deposition, chemical vapor deposition, and sputtering. These techniques allow for the controlled synthesis of materials in thin film form, making them integral to numerous technological applications. A wafer is a thin slice of semiconductor or crystal material. Wafer manufacturing begins with the creation of a cylindrical ingot of highly pure, defect-free monocrystalline material, through methods like the Czochralski process. This ingot is then sliced into thin wafers. After slicing, wafers go through several steps of polishing, cleaning, and, frequently, texturing to optimize their surface properties for the intended application. In microelectronics industry, thin film and wafers are crucial in the production of integrated circuits (ICs). Thin films allow for the precise deposition of conductive, insulative, or semiconductive layers which are essential for creating the intricate architectures of ICs. The resultant microelectronic devices are then etched and patterned to form the desired circuitry, driving the functionality of electronic devices ranging from computers and smartphones to sensors and IoT devices. And wafers are typically used as a platform for the fabrication of ICs. Moreover, they are widely used in sensors, communication devices, optical applications, energy devices, etc.
