SiC Coated Wafer Heater

 

 

Semicorex SiC Coated Wafer Heater represents a state-of-the-art thermal management solution designed specifically for semiconductor wafer processing. Engineered with a high-purity silicon carbide (SiC) coating on a robust graphite substrate, this heater delivers superior performance in high-temperature and corrosive environments, meeting the demanding requirements of modern semiconductor fabrication.

SiC Coated Wafer Heater is often used as components for supporting and heating single crystal substrates in metal organic chemical vapor deposition (MOCVD) equipment. MOCVD equipment is a key equipment for the research and development and industrialization of epitaxial growth of compound semiconductor single crystal substrates. The thermal stability, thermal uniformity and other performance parameters of SiC coated graphite play a decisive role in the quality of epitaxial material growth, so it is the core key component of MOCVD equipment.

β-SiC (3C-SiC) crystal type is selected as the coating. Compared with other crystal types, this crystal type has a series of excellent properties such as good thermodynamic stability, oxidation resistance and corrosion resistance. At the same time, it has a thermal conductivity that is basically the same as that of graphite, so it gives the graphite base special properties, which can effectively solve the failure of the graphite base caused by high temperature oxidation and corrosion powdering during service, so that the surface of the graphite base has the characteristics of dense, non-porous, high temperature resistant, anti-dissolution, and anti-oxidation, thereby improving the quality of crystal epitaxy and the service life of the graphite base.

Uniform heating across the wafer surface is crucial in semiconductor manufacturing processes such as CVD, ALD, diffusion, and oxidation. The SiC Coated Wafer Heater ensures excellent temperature uniformity, minimizing thermal gradients and reducing wafer warpage or defects. Its advanced design provides fast heating and cooling cycles, improving throughput while maintaining tight process control. The SiC coating’s high thermal conductivity enables efficient heat transfer, reducing energy consumption and process time.

Available in a variety of sizes, power ratings, and configurations, the SiC Coated Wafer Heater can be tailored to specific tool platforms and process chambers. Optional features include integrated thermocouples, RTD sensors, and embedded heating elements to ensure precise temperature monitoring and control.

Semicorex SiC Coated Wafer Heater is an ideal choice for semiconductor manufacturers seeking high reliability, purity, and performance in aggressive processing environments. Its superior thermal characteristics, chemical resistance, and long lifespan make it a cost-effective investment for fabs aiming to improve yield, reduce contamination, and optimize process efficiency. With its customizable options and proven durability, the SiC Coated Wafer Heater is a trusted solution for next-generation semiconductor fabrication.
