    摘要: Devices that include a dichroic material sandwiched between first and second electrodes layers and exhibiting a high optical absorption when the first and second electrode layers are biased at a first electrical bias state and a low optical absorption when the first and second electrode layers are biased at a second, different electrical bias state. Such devices may be used to construct optically reflective devices such as anti-glare mirrors and optically transmissive devices such as eye glasses. The dichroic material may be selected to be operable to switch between the high optical absorption and the low optical absorption in less than 0.1 second.

    摘要: The invention provides chemical-mechanical polishing (CMP) compositions and methods for polishing a silicon-containing substrate. A method of the invention comprises the steps of contacting a silicon-containing substrate with a polishing pad and an aqueous CMP composition, and causing relative motion between the polishing pad and the substrate while maintaining a portion of the CMP composition in contact with the surface of the substrate to abrade at least a portion of the substrate. The CMP composition comprises a ceria abrasive, a polishing additive bearing a functional group with a pKa of about 4 to about 9, a nonionic surfactant with an hydrophilic portion and a lipophilic portion wherein the hydrophilic portion has a number average molecular weight of about 500 g/mol or higher, and an aqueous carrier, wherein the pH of the composition is 7 or less. The method reduces defects on the wafers, particularly local areas of high removal. The method is also useful for polishing dielectric silicon-containing substrates at a high rate relative to semiconductor silicon-containing substrates.
