一種晶圓清洗及乾燥方法,用以解決習知晶圓清洗及乾燥製程導致晶圓上的電晶體微結構內縮倒塌的問題。係包含:一傾斜步驟,將一待工元件傾斜,使該待工元件之一加工面朝上,且該加工面與水平面夾一傾斜角度;一沖洗步驟,將一清洗液注入於該加工面;及一乾燥步驟,提高該待工元件周遭的環境溫度,使停留在該加工面上的該清洗液揮發。 A method for cleaning and drying wafer is provided to solve the problem that the conventional process of cleaning and drying wafer causes collapsing of the microstructure of transistor on the wafer. The method includes an obliquing step, a washing step and a drying step. The obliquing step is tilting a processing component so that a processing surface of the processing component is face up. The processing surface and horizontal plane have an inclination angle. The washing step is injecting a cleaning solution into the processing surface. The drying step is increasing ambient temperature around the processing component to volatilize the cleaning solution staying on the processing surface.
