As an important branch in the field of semiconductor materials, silicon carbide conductive semi-insulating substrate, with its unique physical and chemical properties, shows great potential for application in new energy vehicles, photovoltaic, smart grid, rail transportation and wireless communications.
Silicon carbide conductive semi-insulating substrates are divided into two categories, conductive substrates and semi-insulating substrates, according to the difference in resistivity.
Conductive substrates usually refer to silicon carbide substrates with resistivity in the range of 15~30mΩ-cm, while semi-insulating substrates have resistivity higher than 100000Ω-cm. These two types of substrates play a vital role in semiconductor device manufacturing.

wafer size and production efficiency
Wafer is the core material in the semiconductor manufacturing process, its diameter size directly affects the production efficiency and cost.
Silicon carbide wafers are divided into 4-inch, 5-inch, 6-inch, 8-inch, 12-inch and other specifications according to its diameter, of which 12-inch (300mm) wafers are known as large silicon.
The larger the wafer, the greater the number of chips that can be produced on the same wafer, thus reducing costs. However, the production of large-size wafers on the material technology and production technology also put forward higher requirements.
