    摘要: In an embodiment, a trench is formed above a via from a photo resist (PR) trench pattern in a dielectric layer. The trench is defined by two sidewall portions and base portions. The base portions of the sidewalls are locally treated by a post treatment using the PR trench pattern as mask to enhance mechanical strength of portions of the dielectric layer underneath the base portions. Seed and barrier layers are deposited on the trench and the via. The trench and via are filled with a metal layer. In another embodiment, a trench is formed from a PR trench pattern in a dielectric layer. A pillar PR is deposited and etched to define a pillar opening having a pillar surface. The pillar opening is locally treated on the pillar surface by a post treatment to enhance mechanical strength of portion of the dielectric layer underneath the pillar surface.

    摘要: Disclosed is a method for separating and purifying Ginkgolide C from root bark of ginkgo. The method comprises: (1) extracting the root bark of ginkgo with ethanol; (2) concentrating the resulting extract under vacuum to remove ethanol; (3) separating the concentrate by macroporous resin column chromatography; (4) after the concentrate being loaded on the column, washing the column with pure water to remove impurities, and then eluting the column with an ethanol solution; (5) concentrating the eluate under vacuum to dryness to obtain a yellow crude extract; (6) heating the crude extract in water to boiling to form a solution, and then refrigerating the solution; (7) concentrating the supernatant solution and filtering under vacuum to obtain a mixed crude crytal of ginkgolides; (8) dissolving the crude crystal in ethanol to form a supersaturated solution, refrigerating and crystallizing the solution to remove Ginkgolides A and B; (9) concentrating and recrystallizing the mother liquor to obtain a crystal of Ginkgolide C; and (10) recrystallizing the crystal with ethanol several times to obtain a high-purity crystal of Ginkgolide C.

    摘要: A micromachined strain gauge comprising a plastically deformable piezoresistive microstructure formed on a surface of a substrate so that deformation of the substrate plastically deforms the microstructure to thereby change the resistance of the microstructure. The stress in the substrate can be determined from the change in the resistance of the microstructure.
