Samco’s UV ozone cleaning systems offer a sophisticated method for surface treatment by combining ultraviolet (UV) irradiation, ozone, and stage heating. This powerful, yet gentle process effectively removes organic contaminants from a wide range of substrates, including silicon, glass, and compound semiconductors such as GaN, SiC, GaAs, and InP. Available in compact benchtop and cassette-loading configurations, Samco’s UV ozone cleaners cater to both R&D and mass production environments, ensuring versatility and efficiency. With systems designed to handle a variety of materials, UV ozone cleaning is an ideal solution for those seeking a dry, non-invasive method for substrate preparation and contamination removal. UV ozone treatment works by utilizing both 185 nm and 254 nm UV light wavelengths. The 185 nm UV light dissociates molecular oxygen into atomic oxygen, which reacts with ozone to form highly reactive singlet atomic oxygen. This powerful oxidant interacts with the substrate surface to remove organic residues, while the 254 nm UV light dissociates ozone, further enhancing the oxidation process. Additionally, stage heating plays a crucial role by accelerating ozone dissociation at higher temperatures, increasing the concentration of singlet atomic oxygen and improving cleaning efficiency. This process results in the removal of organic contaminants without causing damage to the substrate, making it particularly useful for sensitive materials like semiconductor wafers. The UV ozone cleaning systems also feature an ozone decomposition unit and automatic nitrogen purging for enhanced safety, ensuring a completely dry, chemical-free treatment. COP samples treated with UV Ozone and stage heating, along with ozone flow, maintained stable hydrophilic surfaces for 180 days, demonstrating the long-term effectiveness of UV Ozone treatment compared to oxygen plasma. Ozone generator provides a higher ozone concentration and sample stage heater allows process temperature control up to 300°C. These features increase the reactive oxygen species during the process and improve the etch rate.
