Used IST (Diffusion Furnaces & Accessories) for sale

The diffusion furnace is a key component in the fabrication of semiconductors, allowing for the diffusion of dopant materials into the wafers. IST is a prominent manufacturer of diffusion furnaces and related accessories. IST offers a wide range of diffusion furnaces that cater to different process requirements. Their furnaces are designed to provide precise and consistent diffusion processes, ensuring high-quality results. These furnaces are equipped with advanced features such as multi-zone temperature control, high-purity gas delivery systems, and controlled atmosphere environments. IST also provides a range of accessories that complement their diffusion furnaces. These include quartz tubes, wafer boats, gas systems, and process controls. Quartz tubes are used to hold and transport the wafers during the diffusion process, ensuring uniform diffusion across the wafers. Wafer boats help in loading and unloading the wafers into the quartz tubes efficiently. Gas systems deliver the required dopant gases to the furnace for the diffusion process, while process controls assist in monitoring and controlling the diffusion process parameters. IST diffusion furnaces and accessories have several advantages. They offer high process repeatability, enhanced process uniformity, and superior dopant concentration control. Additionally, their advanced features and precise controls contribute to reduced cycle times and increased yield. IST's VFNC 3030 is an example of their diffusion furnace series. It is a highly efficient and versatile furnace suitable for both batch and single-wafer diffusion processes. The VFNC 3030 offers excellent temperature control, fast ramping rates, and superior dopant gas management, making it ideal for a wide range of semiconductor fabrication applications.
