  • Publication number: 20220216147
    Abstract: A semiconductor device and a method of forming the same are provided. The semiconductor device includes a substrate, a gate structure, a dielectric structure and a contact structure. The substrate has source/drain (S/D) regions. The gate structure is on the substrate and between the S/D regions. The dielectric structure covers the gate structure. The contact structure penetrates through the dielectric structure to connect to the S/D region. A lower portion of a sidewall of the contact structure is spaced apart from the dielectric structure by an air gap therebetween, while an upper portion of the sidewall of the contact structure is in contact with the dielectric structure.

  • Patent number: 9085543
    Abstract: The present invention discloses an inverted organic photovoltaic cell comprising a polymerizable fullerene interlayer adapted to enhance the device performance and lifetime. The polymerizable fullerene derivative comprises a fullerene core, a bridging functional group and a polymerizable functional group. The fullerene core can be either C60 or C70, and the bridging functional group comprises a cyclic hydrocarbon or a heterocyclic ring. The polymerizable functional group comprises a thermally polymerizable functional group or a photochemically polymerizable functional group.

  • Publication number: 20100239711
    Abstract: A method is provided for manufacturing coffee by solid state fermentation, including the following steps: depositing coffee beans in a dust-free clean container; propagating a fungus with solid state fermentation; carrying out implantation process, wherein the fungus is implanted to the coffee beans contained in the dust-free clean container with a sterile operation, the fungus being one belonging to Eumycota, including at least one selected from Basidiomycotina and Ascomycotina; and performing a fermentation process. Also provided is a formula of the solid cultivation medium used in the method, which is suitable for both large-scale and small-scale production of fungi and is applicable to most fungi to not only increase the throughput as desired, but also provide a metabolic product containing pharmacologically active ingredients.

  • Patent number: 6558943
    Abstract: A solid state fermentation (SSF) method is provided which is effective for both small- and large-scale fungal cultivation. Also provided is SSF media for fungal cultivation. The media preferably contains a carbon source and nitrogen source to provide a carbon to nitrogen ratio of about 5:1 to about 25:1 by weight. The media may also contain a vitamin and an inorganic substance. A preferred SSF medium contains malt extract, yeast extract, peptone, glucose, water, solid base, and calcium carbonate or gypsum. Before propagating fungal mycelia in the SSF medium, the mycelia may be pre-cultivated in a solid culture medium and then in a liquid medium. Although the SSF method can be used in growing most fungi, preferred fungi include Cordyceps sinensis, Ganoderma lucidum, Antrodia camphorata, Trametes versicolor, and Agaricus blazei. The SSF method not only produces high yield of fungi, but also stimulates the production of fungal metabolites, particularly the kinds with pharmaceutical and medicinal activities.
