MOCVD, or Metal-Organic Chemical Vapor Deposition, is a process used to create thin films of materials, particularly semiconductors. It involves the chemical reaction of metal-organic compounds and gases at high temperatures, allowing for precise control over the composition and thickness of the films. This technique is essential in the production of devices like LEDs and solar cells. The MOCVD process typically takes place in a specialized chamber where substrates are placed. As the gases flow over the substrate, they decompose and deposit the desired material layer by layer. This method is valued for its ability to produce high-quality films with uniform properties.
