Wafer Heater Design Considerations for 12-Inch Semiconductor Wafers
Good thermal design depends on more than a rated power value. The mounting surface often decides how well the heater performs. A wafer heater uses a controlled heating plate or chuck used to warm semiconductor wafers. You can use these points during design, sourcing, and testing. The aim is steady heat without making the assembly harder to build. Sensors can be placed near key thermal zones. Prototype testing can reveal edge loss and cold zones. The control loop sho
