The TaC Coated MOCVD Graphite Susceptor by Semicera is designed for high durability and exceptional high-temperature resistance, making it perfect for MOCVD epitaxy applications. This susceptor enhances efficiency and quality in Deep UV LED production. Manufactured with precision, Semicera ensures top-notch performance and reliability in every product.
Rivestimento TAC is an important material coating, which is usually prepared on a graphite base by metal organic chemical vapor deposition (MOCVD) technology. This coating has excellent properties, such as high hardness, excellent wear resistance, high temperature resistance and chemical stability, and is suitable for various high-demand engineering applications.
MOCVD technology is a commonly used thin film growth technology that deposits the desired compound film on the substrate surface by reacting metal organic precursors with reactive gases at high temperatures. When preparing Rivestimento TAC, selecting appropriate metal organic precursors and carbon sources, controlling reaction conditions and deposition parameters, a uniform and dense TaC film can be deposited on a graphite base.
Semicera offre rivestimenti specializzati in carburo di tantalum (TAC) per vari componenti e vettori. Il processo di rivestimento leader di semicera consente ai rivestimenti in carburo di tantalum (TAC) per ottenere elevata purezza, stabilità ad alta temperatura e elevata tolleranza chimica, migliorando la qualità del prodotto dei cristalli SIC/GAN e gli strati EPI (EPI (Suscettore TAC rivestito in grafite), 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.
Dopo anni di sviluppo, Semicera ha conquistato la tecnologia di CVD TAC con gli sforzi congiunti del dipartimento di ricerca e sviluppo. I difetti sono facili da verificarsi nel processo di crescita dei wafer SIC, ma dopo aver utilizzato Tac, the difference is significant. Below is a comparison of wafers with and without TaC, as well as Simicera’ parts for single crystal growth.
Moreover, Semicera’s TaC-coated products exhibit a longer service life and greater high-temperature resistance compared to SiC coatings. Laboratory measurements have demonstrated that our TaC coatings can consistently perform at temperatures up to 2300 degrees Celsius for extended periods. Below are some examples of our samples:
