Common Wafer Heater Design Challenges in Semiconductor Equipment
By @industrial-heat-source
A good heating design starts with the job, not the heater alone. Heat loss, contact pressure, and airflow all change the result. A wafer heater uses a controlled heating plate or chuck used to warm semiconductor wafers. The goal is a setup that is easy to build and control. The aim is steady heat without making the assembly harder to build. The design can include vacuum hold-down or chuck features. Prototype testing can reveal edge loss and cold zones. Vacuum ports
