A wafer, also called a substrate,is a thin slice of semiconductor material, such as a crystalline silicon,used in electronics for the fabrication of integrated circuit and in photovoltaics for conventional, wafer-based solar cells.Silicon wafers are a key component in integrated circuits. Integrated circuits are, simply put, a composite of various electronic components that are arranged to perform a specific function. Silicon is the principle platform for semiconductor devices.As a vertical material supplier,Al-60%Si alloy or Al-70%Si alloy chosen are typically used in high-brightness light emitting diode(LED) and photovoltaic cells.
There are different silicon fabrication methods including the horizontal gradient freeze method, the horizontal bridgeman method, the vertical bridgeman method, the vertical gradient freeze and finally the Czochralski pulling method.During the growth process intentional addtions of dopants can be added to change the purity of the silicon depending on what the purpose of it will be. These introduced impurities can change the electrical properties of the silicon, which can be useful depending on what the silicon is ultimately being produced for.
