Silicon is reaching its limits, and gallium nitride (GaN) has emerged as a potential replacement semiconductor material. GaN’s wide band gap enables smaller power devices with equal performance – thus saving energy consumption and carbon emissions. Producing high-quality GaN chips requires much hard work. One of the main hurdles lies in manufacturing processes that are slower and more energy intensive than those typically used with silicon technology. Thermal Conductivity Silicon carbide (SiC) and gallium nitride (GaN) semiconductors have brought revolution to power electronics, surpassing traditional silicon (Si) technology in several key categories like efficiency, heat dissipation and power density. Yet these wide bandgap (WBG) semiconductors differ in some critical ways …

Silicon Carbide powders have a wide variety of uses that require toughness and hardness, including applications in abrasives for hardness, refractories and ceramics for their resistance to high heat and thermal shock as well as electronics due to thermal conductivity. Pure SiC is produced through the Lely method, in which a granite crucible is heated to high temperatures before SiC sublimes onto graphite at lower temperatures and forms. Chemical vapor deposition techniques may also be employed. Abrasive Applications Black silicon carbide’s hardness makes it an invaluable material in abrasive applications such as creating sandpaper, grinding wheels and cutting tools. Furthermore, its thermal and strength stability makes it perfect for producing …

Silicon carbide (SiC) can be difficult to polish due to its extreme hardness. Chemical polishing is therefore frequently employed in order to produce high-quality surfaces finishes. CMP uses both chemical reactions and mechanical removal techniques to planarize SiC wafers. In the CMP process, an oxidant in the polishing slurry reacts with SiC samples to form an oxide film on their surfaces that can then be mechanically removed by using abrasive particles as part of an abradant layer removal solution. Chemical Mechanical Polishing Chemical Mechanical Polishing (CMP) is an integral step in the creation of integrated circuits (ICs), making silicon wafer surfaces uniformly flat by using chemical reactions and mechanical abrasion …
