Single Wafer Wet Process System

JST’s single wafer wet process system utilizes an automated chemical spray process on a single wafer. The system includes programmable oscillating spray nozzles, wafer speed (RPM), and precision adjustment of the distance between the nozzles and the surface of the wafer. Automated dispense from the chemical storage reservoir provides repeatable control of volume and mixing. The spin chucks are designed for either DIW backside rinsing or backside isolation. This system is offered with either auto or manual wafer loading/unloading configurations. As with all JST wet benches, they are designed for ease of maintenance activities and come with our standard 24/7 Technical Support.
