发明名称 Method for air gap formation using UV-decomposable materials
摘要 A method of selectively removing a sacrificial material on a substrate is described. The method comprises forming a sacrificial layer on a substrate. Thereafter, the sacrificial layer is selectively decomposed at a temperature less than the temperature required to thermally decompose the sacrificial layer by selectively exposing the sacrificial layer to UV radiation.
