Used DENGYNG DF-40 #9309231 for sale

DENGYNG DF-40 is a vertical-type diffusion furnace and accessories which offer a reliable low temperature diffusion processing of a wide range of materials. The furnace can be used for both oxidizing and reducing atmospheres and can be operated in either stationary or high temperature ranges up to 1300°C (2370°F). The standard configuration of DF-40 features a vertical chamber with a dual-stage design, which allows for simultaneous diffusion of multiple wafers. The dual-stage design passes a heated gas rich in reactant across the heated wafers, followed by a cool down in a neutral gaseous atmosphere. This technique allows for uniformity in the process and minimizes and eliminates the need for a post-diffusion cleaning step. DENGYNG DF-40 is capable of accommodating up to eight pieces of 6 inch (150mm) wafers with ease due to its heavy-duty load basket. The upper chamber measures 12 inches (380mm) in diameter making it ideal for thin films with high thickness uniformity. It is also equipped with an automated shut-off system, which safeguards the process from unnecessary damage and overheating. The diffusion furnace has a convenient and easily readable control panel, where all the user settings are available at glance. The automatic recipe programming feature helps users to save time by pre-setting the necessary parameters for a given process for quick and easy reproduction. DF-40 is also fitted with a two-zone heat-zone temperature control system, which allows for the precise control of temperature and production time. The exterior of DENGYNG DF-40 is embedded with a number of important features such as air flow adjustment pin gauge, an air inlet control valve, and a digital timer. Additionally, both over-temperature and under-temperature sensors are installed to ensure safety and accuracy during the diffusion process. Safety locks are installed on both sides, allowing the user to lock the chamber with a key. To make sure the process is energy efficient, the device is equipped with Teflon insulation, which helps reduce energy consumption. The frequency converter is adjustable and allows for various operation times. DF-40 is also available with a variety of other options such as a sleeve, gas mixing, etc. for various specific diffusion requirements. Overall, DENGYNG DF-40 is a reliable and efficient tool designed for both research and industrial applications, offering an ideal solution for low temperature diffusion processing. It is easy to operate and has a self-diagnostic system ensuring the highest standards in safety and accuracy.
