TurboDisc K 465 GaN MOCVD
What it is
The Veeco TurboDisc K 465 is a metal organic chemical vapor deposition (MOCVD) system designed for gallium nitride (GaN) epitaxial growth.[1][2]
How it works
General reference — not yet source-verifiedA MOCVD reactor deposits thin crystalline layers on a substrate through chemical reactions of metal organic precursor gases with a hydride source, typically ammonia for nitrogen, at elevated temperature.
The TurboDisc name refers to a rotating-disk reactor design that improves layer uniformity and allows deposition on multiple wafers simultaneously.
Where it fits in the process flow
General reference — not yet source-verifiedAfter MOCVD growth, wafers proceed to device fabrication steps such as lithography, etching, and metallization to produce GaN-based optoelectronic or power devices.

Frequently asked questions
What are the main maintenance considerations for such an MOCVD system?General reference — not yet source-verified
Key maintenance concerns include managing the purity and delivery of metal‑organic precursors (which are often pyrophoric or toxic), regular cleaning of the reactor chamber to remove deposited by‑products, and monitoring the integrity of the rotation mechanism and heating elements. Additionally, the gas supply lines and exhaust scrubbing systems require periodic inspection to ensure safe and reliable operation.
What types of substrates are typically used in this system?General reference — not yet source-verified
Machines of this class are typically configured to accept substrates such as sapphire, silicon carbide, and silicon. The choice of substrate depends on the target device application, as lattice mismatch and thermal expansion properties influence epitaxial quality. The system's susceptor is designed to accommodate wafers of various sizes, though exact dimensions vary by model.
What is the role of the metal‑organic precursor in the MOCVD process?General reference — not yet source-verified
Metal‑organic precursors supply the group‑III elements (e.g., gallium, aluminum, indium) in a vapor phase. In the reactor, these precursors decompose on the heated substrate surface, releasing the metal atoms that then react with nitrogen from hydride gases (such as ammonia) to form the compound semiconductor layer. The flow rates of these precursors are precisely controlled to set the composition and growth rate of the epitaxial film.
