With the rapid development of new technologies such as AI, Internet of Things, 5G, etc. driving the demand for huge amounts of data computing, in addition to the use of high-speed computing chips, inter-chip communication is another way to improve operation. ... Read more

The grown silicon carbide monocrystalline anchors are then subjected to a cutting process. Due to its hardness and brittle characteristics, it is difficult to cut the ingots and is prone to wear and tear. ... Read more

The production of silicon carbide substrate needs to go through the process steps such as long crystal, cutting, edge guiding, grinding, polishing, cleaning, shipment inspection, etc., among which the key to affect the quality is long crystal, cutting, and so on. ... Read more
