A wafer is a thin slice of semiconductor material, such as a crystalline silicon, used in electronics for the fabrication of integrated circuits and in photovoltaics for conventional, wafer-based solar cells. Wafer sizes and dimensions differ depending on how it’s being used. Because of its unique characteristics, ultra flat wafers have very specific uses. Here is more on this type of wafer and where you would find it.
Silicon wafers are measured in microns. Ultra flat wafers are wafers that are under 200 microns thick. The thickness of the wafer determines what kind of integrated circuits are used and if the wafer is ideal for supporting cells.
Ultra flat silicon wafers have higher specifications than standard ones. As a result, the ultra-flat wafers are preferred for demanding applications in micro-fabrication. This includes substrates for thin film research or biological substrates. They are also popular in the electronics and biological industries. The excellent ultra-flat surface is perfect for high-resolution SEM imaging of particles due to the low background signal.
