Mainstream Debonding Methods

Temporary bonding and debonding technologies are typically applied to guarantee the stable performance and production yield of semiconductor devices. The ultra-thin wafer is temporarily fixed onto a rigid carrier substrate, and after backside processing, the two are separated. This separation proces......

Silicon Carbide Wafer Boats: the "invisible guardians of wafers" in Semiconductor

In semiconductor manufacturing, oxidation involves placing the wafer in a high-temperature environment where oxygen flows across the wafer surface to form an oxide layer. This protects the wafer from chemical impurities, prevents leakage current from entering the circuitry, prevents diffusion during......

Common Semiconductor Quartz Components and Applications

Quartz belongs to trigonal crystal system, which is a three-dimensional framework mineral crystal composed of silicon dioxide. Typically, pure quartz is colorless and transparent, but it takes on a variety of hues as a result of trace pigment ions, finely dispersed inclusions or the formation of col......

What is the Silicon Carbide?

SiC material is not composed of a single tetrahedron of one Si atom and one C atom, but of countless Si and C atoms. A large number of Si and C atoms form undulating double atomic layers (one layer of C atoms and one layer of Si atoms), and numerous double atomic layers stack to form SiC crystals. D......

What are the Challenges in Fabricating of SiC Substrates?

The manufacturing and processing of high-quality silicon carbide substrates involve extremely high technical barriers. Numerous challenges persist across the entire process, from raw material preparation to finished product fabrication, which has become a crucial factor restricting its large-scale ......

What are Carbon-Ceramic Brake Discs?

Carbon-ceramic brake discs are high-performing brake solutions precisely made of carbon fiber-reinforced silicon carbide-based composite materials, whose technical origins can be traced back to aircraft braking field in the 1970s. Leveraging the high strength and toughness of carbon fiber and the hi......
