Used Diffusion Furnaces & Accessories for sale
Diffusion furnaces and accessories play a crucial role in the semiconductor industry, specifically in the process of creating thin films on silicon wafers. These furnaces are designed to provide a controlled environment, ensuring the diffusion process is carried out with precision and accuracy. Diffusion furnaces are made up of several key components, including a furnace chamber, a gas delivery system, a temperature control system, and a wafer carousel. The furnace chamber is where the wafers are placed and subjected to high temperatures, typically between 800 and 1200 degrees Celsius. This high temperature allows the dopant atoms to diffuse into the silicon substrate, altering its electrical properties. The gas delivery system is responsible for delivering the dopant gases into the furnace chamber. These gases are carefully selected based on the desired electrical properties of the final product. The temperature control system ensures that the furnace operates at the desired temperature and maintains temperature uniformity throughout the process. The wafer carousel holds the silicon wafers and rotates them during the diffusion process. This rotation ensures that the dopant gases are evenly distributed across the wafers, resulting in uniform doping. In addition to the diffusion furnace, there are several accessories that are commonly used in conjunction with the furnace. These include quartz boats, which hold the wafers during the diffusion process, and loading tools for safe and efficient handling of wafers. Overall, diffusion furnaces and accessories are essential tools in the semiconductor industry, enabling the precise control and uniform distribution of dopant atoms onto silicon wafers. This plays a critical role in the fabrication of high-performance semiconductor devices.
