Wafers are commonly used in snacks, desserts, and confections, providing a light and crunchy texture. They can be found in various flavors and are often layered with creams or fillings. In the technology sector, a wafer refers to a thin slice of semiconductor material, such as silicon, used in the manufacturing of integrated circuits and microchips. These wafers are essential components in electronic devices, including computers and smartphones, enabling complex functionalities in modern technology.
