Abstract: A contact structure according to the present disclosure includes a conductive feature, an etch stop layer (ESL) over the conductive feature, a dielectric layer over the ESL, and a contact feature extending through the dielectric layer and the ESL to contact the conductive feature. The dielectric layer includes a low-k dielectric matrix material, and nano-pipes disposed in the low-k dielectric matrix material and configured to reduce a thermal resistance of the dielectric layer.

Abstract: A tattoo needle structure is provided. A tattoo needle has a plurality of needle tips, an ink holding space is formed by the arrangement of the needle tips, and a multi-component alloy film is deposited on each needle tip of the tattoo needle by sputtering technology, so that when the tattoo needle is dipped into the tattoo ink, the tattoo ink does not stick to the surface of the multi-component alloy film by the hydrophobic property of the multi-component alloy film, and the tattoo ink is contained in the ink holding space by the cohesive property of the tattoo ink. Thus, when the tattoo needle is dipped into the tattoo ink and the tattoo process is performed, the dyeing area of the skin with the tattoo ink is the cross-sectional area of the ink holding space, thereby achieving the technical effect of improving the contouring resolution of a tattoo.

Abstract: A production method of enzyme containing Antrodia Cinnamomea component includes steps of: filling fruits of the season and Antrodia Cinnamomea in eighty percent full in the internal space of a container to be sealed off and adding a yeast for a first yeast fermentation for a period of 30 days; then stuffing the same container with the fruits of the season for a second yeast fermentation for a period of 30 days; injecting air into the container when alcohol level goes lower than 12% and adding an acetic acid bacteria for an acetic acid fermentation for a period of 120˜180 days. Through two times of alcoholic extraction, followed with the acetic acid extraction, the particular bioactive components of Antrodia Cinnamomea may be fully obtained and carried with the natural enzyme drinks.
