摘要： A method of integrating a post-etching cleaning process with deposition for a semiconductor device. A substrate having a damascene structure formed by etching a dielectric layer formed thereon using an overlying photoresist mask as an etching mask is provided. A cleaning process is performed by a supercritical fluid to remove the photoresist mask and post-etching by-products. An interconnect layer is formed in-situ in the damascene structure using the supercritical fluid as a reaction medium, wherein the cleaning process and the subsequent interconnect layer formation are performed in one process chamber or in different process chambers of a processing tool.

摘要： System and method for reducing damage to a semiconductor substrate when using cleaning fluids at elevated pressures to clean the semiconductor substrates. A preferred embodiment comprises applying the cleaning fluid at a first pressure for a first time period, wherein the first pressure is relatively low, and then increasing the pressure of the cleaning fluid to a pressure level that can effectively clean the semiconductor substrate and maintaining the pressure level for a second time period. The application of the cleaning fluid at the relatively low initial pressure acts as a temporary filler and creates a buffer of the cleaning fluid on the semiconductor substrate and helps to dampen the impact of the subsequent high pressure application of the cleaning fluid on the semiconductor substrate.

摘要： An organic layer, such as a porous low-K dielectric in an IC, contains pores open at its surface. To close the pores, the organic layer is contacted by a supercritical fluid that is a solvent for the layer. After a small amount of the surface and the wall of the open pores is solvated, a phase transition of the solvated organic material is effected at the surface to cover it with a dense, smooth, non-porous film that seals the open pores.
