TaC coating is a new generation of high temperature resistant material, with better high temperature stability than SiC, serving as a corrosion-resistant, oxidation-resistant, and wear-resistant coating, can be used in the environment above 2000℃, widely used in aerospace ultra-high temperature hot end parts, the third generation of semiconductor single crystal growth and other fields.
Semicera offre rivestimenti specializzati in carburo di tantalum (TAC) per vari componenti e vettori. Semicera leading coating process enables tantalum carbide (TaC) coatings to achieve high purity, high temperature stability and high chemical tolerance, improving product quality of SIC/GAN crystals and EPI layers (Graphite coated TaC susceptor), and extending the life of key reactor components. The use of tantalum carbide TaC coating is to solve the edge problem and improve the quality of crystal growth, and Semicera has breakthrough solved the tantalum carbide coating technology (CVD), reaching the international advanced level.
After years of development, Semicera has conquered the technology of CVD TaC with the joint efforts of the R&D department. Defects are easy to occur in the growth process of SiC wafers, but after using TaC, the difference is significant. Below is a comparison of wafers with and without TaC, as well as Semicera’ parts for single crystal growth
Inoltre, la durata della durata dei prodotti TAC di semicera è più lunga e più resistente alle alte temperature di quella del rivestimento SIC. Dopo un lungo periodo di dati di misurazione di laboratorio, il nostro TAC può funzionare a lungo al massimo di 2300 gradi Celsius. Di seguito sono riportati alcuni dei nostri campioni:
