    摘要: Methods and apparatus for forming through-vias are presented, for example, a method for forming a via in a portion of a semiconductor wafer comprising a substrate. The method comprises forming a trench surrounding a first part of the substrate such that the first part is separated from a second part of the substrate, forming a hole through the substrate within the first part, and forming a first metal within the hole. The trench extends through the substrate. The first metal extends from a front surface of the substrate to a back surface of the substrate. The via comprises the hole and the first metal.

    摘要: A method of patterning and releasing chemically sensitive low k films without the complication of a permanent hardmask stack, yielding an unaltered free-standing structure is provided. The method includes providing a structure including a Si-containing substrate having in-laid etch stop layers located therein; forming a chemically sensitive low k film and a protective hardmask having a pattern atop the structure; transferring the pattern to the chemically sensitive low k film to provide an opening that exposes a portion of the Si-containing substrate; and etching the exposed portion of the Si-containing substrate through the opening to provide a cavity in the Si-containing substrate in which a free-standing low k film structure is formed, while removing the hardmask. In accordance with the present invention, the etching comprises a XeF2 etch gas.
