    摘要: The present invention provides a process of manufacturing a semiconductor device 200 while reducing silicon loss. In one aspect, the process includes removing a photoresist layer 270 from a semiconductor substrate 235 adjacent a gate 240 and cleaning the semiconductor substrate with a wet clean solution. The removing step includes subjecting the photoresist layer 270 to a plasma ash. The plasma ash removes at least a portion of a crust 275 formed on the photoresist layer 270 but leaves a substantial portion of the photoresist layer 270. The photoresist layer 270 is subjected to a wet etch subsequent to the plasma ash that removes a substantial portion of the photoresist layer 270.

    摘要: The present invention provides, in one embodiment, a method of forming a copper layer (100) over a semiconductor substrate (105). The method comprises coating a copper seed layer (110) located over a semiconductor substrate with a protective agent (120) to form a protective layer (125). The method also includes placing the semiconductor substrate in an acid bath (145) to remove the protective layer. The method further includes electrochemically depositing a second copper layer (155) on the copper seed layer. Such methods and resulting conductive structures thereof may be advantageously used in methods to manufacture integrated circuits comprising copper interconnects.

    摘要: The present invention provides a method for manufacturing an integrated circuit. In one embodiment, the method includes etching one or more openings within a substrate using an etch tool, and subjecting the one or more openings to a post-etch clean, wherein a delay time exists between removing the substrate from the etch tool and the subjecting the one or more opening to the post-etch clean. This method may further include exposing the substrate having been subjected to the post-etch clean to a rinsing agent, wherein a resistivity of the rinsing agent is selected based upon the delay time.
