    摘要： The present invention provides methods and compositions for expanding the scope of chemical reactions that can be performed during nucleic acid-templated organic syntheses. In particular, nucleic acid-templated chemistries are used to produce reaction intermediates attached to an oligonucleotide that can be used to identify the reaction intermediates and/or the resulting reaction products. The reaction intermediates then are reacted with free reactants (for example, reactants that are difficult or impractical to couple to an oligonucleotide) to produce a reaction product. This approach expands the scope of reagents useful in nucleic acid-templated syntheses to reagents that do not need to be or cannot be tethered to an oligonucleotide. The reagents, however, still permit the synthesis of reaction products attached to oligonucleotides that can be used to identify the reaction products.

    摘要翻译： 本发明提供用于扩大可以在核酸模板化有机合成过程中进行的化学反应范围的方法和组合物。 特别地，核酸模板化学物质用于产生连接到寡核苷酸上的反应中间体，其可用于鉴定反应中间体和/或所得反应产物。 然后将反应中间体与游离反应物（例如，与寡核苷酸偶联困难或不切实际的反应物）反应以产生反应产物。 这种方法将可用于核酸模板合成的试剂的范围扩大到不需要或不能束缚于寡核苷酸的试剂。 然而，试剂仍然允许合成与可用于鉴定反应产物的寡核苷酸连接的反应产物。

    摘要： A plasma cleaning method for removing residues previously formed in a plasma treatment chamber by dry etching layers such as photoresist, barriers, etc., on a wafer. The method includes introducing a cleaning gas mixture of an oxidizing gas and a chlorine containing gas into the chamber followed by performing a plasma cleaning step. The plasma cleaning step is performed by activating the cleaning gas mixture and forming a plasma cleaning gas, contacting interior surfaces of the chamber with the plasma cleaning gas and removing residues on the interior surfaces. The cleaning gas mixture can also include a fluorine-based gas. For instance, the cleaning gas can include Cl.sub.2 and O.sub.2 and optionally CF.sub.4. An advantage of the cleaning method is that it is not necessary to open the plasma treatment chamber. Also, it is possible to completely remove all residues and prevent by-products formed during the cleaning step from remaining after the cleaning step.

    摘要： An apparatus for plasma etching or plasma deposition including a housing having a chamber in which a wafer can be treated with plasma. The housing includes at least one inlet port connected to an interior of the chamber through which process gas can be supplied to the chamber. A radiofrequency energy source is arranged to pass radiofrequency energy into the chamber and induce plasma in the interior of the chamber by activating, with an electric field induced by the radiofrequency energy source, process gas supplied to the chamber through the inlet port. A dielectric window having an inner surface thereof forms part of an inner wall of the chamber. Radiofrequency energy passes from the radiofrequency energy source to the interior of the chamber through the dielectric window. The dielectric window has a thickness which varies at different points along the inner surface thereof such that the thickness is largest at a central portion of the dielectric window. The dielectric window is effective to decrease the induced electric field in the interior of the chamber near the central portion of the dielectric window.
