摘要： A method of forming an aluminum oxide layer is provided. The method includes providing a metal surface including at least one metal of a group of metals, the group of metals consisting of copper, aluminum, palladium, nickel, silver, and alloys thereof. The method further includes depositing an aluminum oxide layer on the metal surface by atomic layer deposition, wherein a maximum processing temperature during the depositing is 280° C., such that the aluminum oxide layer is formed with a surface having a liquid solder contact angle of less than 40°.
