Silicon wafer is an important material for making integrated circuits, which can be made into various semiconductor devices by means of photolithography and ion implantation.
Since silicon is one of the most abundant elements in the Earth's crust, the advantage of reserves is also one of the reasons why silicon has become the main material for photovoltaic products such as solar cells that are destined to enter the mass market.
For the manufacture of semiconductor components and integrated circuits (ics). Pure silicon wafers must first be made, and then various processes (photoetching, doping, etc.) must be used to make conductive semiconductor circuits on the silicon wafers.
On the same size silicon chip, a larger number of circuits can be made, that is, a higher degree of integration can be achieved.
At the same time, because the distance between the circuits is small, the length of the wire is short, the required working voltage is lower, which can reduce power consumption and improve the running speed. For silicon-based photovoltaic cells, crystalline silicon (c-Si) raw materials and cutting costs account for the largest portion of the total cost of the cell.
Photovoltaic cell manufacturers can reduce costs by saving silicon in the slicing process.
This effect can be achieved by reducing the cutting loss, which is mainly related to the diameter of the cutting line and is the raw material loss generated by the cutting process itself. Increase machine output.
Making silicon wafers thinner also reduces the amount of silicon consumed.
In the past decade or so, the wafer thickness will become 100μm. The benefits of reducing the wafer thickness are amazing, from 330μm to 130μm, photovoltaic cell manufacturers can reduce the overall silicon raw material consumption by up to 60%.
Silicon wafers are thin sheets made of monocrystalline silicon that are commonly used to make microelectronic devices such as solar panels and integrated circuits. The silicon wafer manufacturing process mainly includes wafer growth, cutting and polishing steps.
Semiconductors are a class of materials with resistance characteristics between conductors and insulators. Common semiconductor materials include silicon, germanium, gallium arsenide, and so on. Semiconductor materials can generate electrons and holes under the action of applied electric field or light, and form electron-hole pairs, so as to achieve the function of electronic devices. The properties of semiconductor materials make it widely used in the electronics industry, such as manufacturing integrated circuits and solar panels.
