    摘要: A method of performing an ultraviolet (UV) curing process on an interfacial layer over a semiconductor substrate, the method includes supplying a gas flow rate ranging from 10 standard cubic centimeters per minute (sccm) to 5 standard liters per minute (slm), wherein the gas comprises inert gas. The method further includes heating the interfacial layer at a temperature less than or equal to 700° C. Another method of performing an annealing process on an interfacial layer over a semiconductor substrate, the second method includes supplying a gas flow rate ranging from 10 sccm to 5 slm, wherein the gas comprises inert gas. The method further includes heating the interfacial layer at a temperature less than or equal to 600° C.
