摘要: System and method for reducing substrate warpage in a thermal process. An embodiment comprises pre-heating a substrate in a loadlock chamber before performing the thermal process of the substrate. After the thermal process, the substrate is cooled down in a loadlock chamber. The pre-heat and cool-down process reduces the warpage of the substrate caused by the differences in coefficients of thermal expansion (CTEs) of the materials that make up the substrate.
