A polymer dispersion may include a water soluble copolymer, a water soluble salt, a polyol, and water. A method of preparing a polymer dispersion may include controlled radical polymerization. A method of using the polymer dispersion as a friction reducer in oil field processes.

Polymer dispersion by controlled radical polymerization

A method for fabricating an integrated circuit device includes providing a semiconductor substrate having a first region and a second region, e.g., peripheral region. The method forms a stop layer overlying the first and second regions and a low k dielectric layer (e.g., k&#x3c;2.9) overlying the stop layer in the first and second regions. The method forms a cap layer overlying the low k dielectric layer. In an embodiment, the method initiates formation of a plurality of via structures within a first portion of the low k dielectric layer overlying the first region and simultaneously initiates formation of an isolated via structure for in the second region of the semiconductor substrate, using one or more etching processes. The method includes ceasing formation of the plurality of via structures within the first portion and ceasing formation of the isolated via structure in the second region when one or more portions of stop layer have been exposed.
