    摘要: A method and apparatus for selectively controlling deposition rate of conductive material during an electroplating process. Dopants are predominantly incorporated into a conductive seed layer on field regions of a substrate prior to filling openings in the field regions by electroplating. A substrate is positioned in one or more processing chambers, and barrier and conductive seed layers formed. A dopant precursor is provided to the chamber and ionized, with or without voltage bias. The dopant predominantly incorporates into the conductive seed layer on the field regions. Electrical conductivity of the conductive seed layer on the field regions is reduced relative to that of the conductive seed layer in the openings, resulting in low initial deposition rate of metal on the field regions during electroplating, and little or no void formation in the metal deposited in the openings.

    摘要: This invention relates to a novel soy isoflavone product with high purities and strong biological activities and the method of producing the same from natural soybeans, soybean materials (i.e. tofu dregs, soy molasses) and other plant sources. The method includes three steps consisting of extraction with an organic solvent, hydrolysis using an acid and crystallization using an antisolvent. The procedure is very simple and thus can be easily adapted for large-scale manufacturing. Moreover, the procedure is able to produce a high yield of total isoflavones at a lower cost. HPLC analysis and E-Screen bioassay reveal that the obtained product not only contains a high content of isoflavone aglycones by weight of dry matter but also exhibits strong estrogenic activity toward human cells. Therefore, the product should be efficacious for relieving menopausal symptoms and other estrogen-deficient diseases and can be used in health care supplements or as additives for foods, beverages or cosmetics.

    摘要: Embodiments of the present invention generally relate to methods for physical vapor deposition processes. The methods generally include synchronizing process chamber conditions with the position of a magnetron. As the magnetron is scanned over a first area of a target, the conditions within the chamber are adjusted to a first set of predetermined process conditions. As the magnetron is subsequently scanned over a second area of the target, the conditions within the chamber are adjusted to a second set of predetermined process conditions different the first set. The target may be divided into more than two areas. By correlating the position of the magnetron with different sets of process conditions, film uniformity can be improved by reducing center-to-edge non-uniformities, such as re-sputter rates which may be higher when the magnetron is near the edge of the target.
