Where is the spin-coating industry headed?

Subscribe to Our Blog

We sat down with our engineers to get their insights on where the spin-coating industry is headed. We were met with an overwhelming response identifying the need for data streaming in real time. Although the spin-coating process is considered to be very efficient, there is always room for improvement. Real-time data monitoring and process transparency could be a “game changer.”

The current spin-coating process

The current process involves three basic steps – dispense, spin, and dry. Within those three steps, multiple factors can affect the coating process, including:

  • Spin speed
  • Acceleration
  • Spin time
  • Exhaust

Today we can only monitor the data at specific intervals during the spin-coating process – for example, when the wafer is not moving. Unfortunately, most defects typically occur when the wafer is in motion.

Why real-time monitoring will help
As the industry demands more consistency and efficiency, real-time data monitoring will allow us to identify when defects occur. One of the most common defects in spin coating is a striation – the development of a thick ridge during the spin-coating process. Because coated layers need to be uniform and flat, knowing the exact moment a defect occurs not only helps determine its root cause but also allows the user to develop a solution and increases the overall efficiency of the process. 

Obtaining information in real time makes it easier to track trends and account for defects when they occur, which increases consistency and efficiency while fueling our drive for innovation at Brewer Science. We’re excited to play our part as the industry grows. Learn how we can help your manufacturing process improve consistency and efficiency by contacting us online or by calling 1-573-364-0300.
