Diamond, a potential fourth-generation "ultimate semiconductor," is gaining attention in semiconductor substrates due to its exceptional hardness, thermal conductivity, and electrical properties. While its high cost and production challenges limit its use, CVD is the preferred method. Despite doping and large-area crystal challenges, diamond holds promise.

In the process of growing silicon carbide (SiC) crystals via the Physical Vapor Transport (PVT) method, the extreme high temperature of 2000–2500 °C is a “double-edged sword” — while it drives the sublimation and transport of source materials, it also dramatically intensifies impurity release from all materials within the thermal field system, especially trace metallic elements contained in conventional graphite hot-zone components. Once these impurities enter the growth interface, they will directly damage the core quality of the crystal. This is the fundamental reason why tantalum carbide (TaC) coatings have become a “mandatory option” rather than an “optional choice” for PVT crystal growth.

Smart cut is an advanced semiconductor manufacturing process based on ion implantation and wafer stripping, specifically designed for the production of ultra-thin and highly uniform 3C-SiC (cubic silicon carbide) wafers. It can transfer ultra-thin crystal materials from one substrate to another, thereby breaking the original physical limitations and changing the entire substrate industry.
