The origin of the name epitaxial wafer
First, let’s popularize a small concept: wafer preparation includes two major links: substrate preparation and epitaxial process. The substrate is a wafer m...
First of all, we need to know PECVD (Plasma Enhanced Chemical Vapor Deposition). Plasma is the intensification of the thermal motion of material molecules. The collision between them will cause the...
In the rapidly evolving semiconductor industry, materials that enhance performance, durability, and efficiency are critical. One such innovation is Tantalum Carbide (TaC) coating, a cutting-edge pr...
SiC/SiC has excellent heat resistance and will replace superalloy in the application of aero-engine
High thrust-to-weight ratio is the goal of advanced aero-engines. However, with the increase of t...
