摘要:
A method of cleaning semiconductor wafers using an acid cleaner followed by an alkaline cleaner to clean contaminants from the materials is provided. The acid cleaner removes substantially all of the metal contaminants while the alkaline cleaner removes substantially all of the non-metal contaminants, such as organics and particulate material.

摘要:
Provided are compositions which include a polymer, having units of the formula (RSiO 1.5 ), wherein R is a substituted or unsubstituted organic group, and a plurality of functional end groups. A first component is provided for altering the solubility of the composition in a dried state upon activation. A second component contains a plurality of functional groups chosen from epoxides, oxetanes, vinyl ethers and combinations thereof. The second component is present in an effective amount to improve flexibility of the composition in a dried state before and after activation. Also provided are flexible optical waveguides, methods of forming flexible optical waveguides and electronic devices that include a flexible optical waveguide.
