Abstract
The present disclosure provides a semiconductor fabrication apparatus. The semiconductor apparatus includes a processing chamber for etching; a substrate stage integrated in the processing chamber and being configured to secure a semiconductor wafer; a reflective mirror configured inside the processing chamber to reflect thermal energy from the heating mechanism toward the semiconductor wafer; and a heating mechanism embedded in the process chamber and is operable to perform a baking process to remove a by-product generated during the etching. The heating mechanism is integrated between the reflective mirror and a gas distribution plate of the processing chamber.
