Wafer Heater Basics: Understanding Thermal Control in Semiconductor Processing
Surface heating looks simple until fit, power, and control meet. 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. It also shows where simple checks can prevent costly redesigns. The aim is steady heat without making the assembly harder to build. The heater can be built for common wafer diameters. Test the heater on the real part when the process is critical. Vac
