CVD Diamond Applications in Semiconductor Technology

This white paper discusses the use of chemical vapor deposition (CVD) diamond in semiconductor applications. It identifies the challenges presented by decreasing feature sizes and increasing power demands in advanced semiconductor devices. The material properties of diamond, including its high thermal conductivity, electrical insulating nature, and semiconducting potential when doped, make it a candidate for next-level performance in various applications, especially in quantum computing and medium-to-high power regimes. The paper also covers the process of high-pressure high-temperature (HPHT) synthesis of artificial diamonds and contrasts polycrystalline and single crystal diamonds. Additionally, it elaborates on the epitaxial growth of diamond films through microwave plasma CVD processes, explaining the mechanisms of homoepitaxy and heteroepitaxy. The unique applications of diamond in electronic devices, optics, and quantum technology are also explored, emphasizing the importance of controlled doping to achieve desired properties.
