Abstract: A method of forming a semiconductor device includes forming a photoresist layer over a mask layer, patterning the photoresist layer, and forming an oxide layer on exposed surfaces of the patterned photoresist layer. The mask layer is patterned using the patterned photoresist layer as a mask.

Abstract: A method of forming a semiconductor device includes forming a mask layer over a substrate and forming an opening in the mask layer. A gap-filling material is deposited in the opening. A plasma treatment is performed on the gap-filling material. The height of the gap-filling material is reduced. The mask layer is removed. The substrate is patterned using the gap-filling material as a mask.

Abstract: A blood pressure detection device manufactured by a semiconductor process includes a substrate, a microelectromechanical element, a gas-pressure-sensing element, a driving-chip element, an encapsulation layer and a valve layer. The substrate includes inlet apertures. The microelectromechanical element and the gas-pressure-sensing element are stacked and integrally formed on the substrate. The encapsulation layer is encapsulated and positioned on the substrate. A flowing-channel space is formed above the microelectromechanical element and the gas-pressure-sensing element. The encapsulation layer includes an outlet aperture in communication with an airbag. The driving-chip element controls the microelectromechanical element, the gas-pressure-sensing element and valve units to transport gas.

Abstract: Disclosed herein are novel uses of avenaciolide derivatives and the preparation method of producing the same. The avenaciolide derivatives may suppress or inhibit the growth of gram-positive bacteria, including the notorious methicillin-resistant Staphylococcus aureus. Accordingly, the avenaciolides derivatives are potential lead compounds for the development of next generation antibiotics for the treatment of disease and/or disorders related to infection caused by gram-positive bacteria.

Abstract: An engine carburetor freeze-proof apparatus that is compact in structure to minimize its impact upon the arrangement of member parts of the vehicle and lowers production cost by providing a pipe to the engine to connect a heating joint of the carburetor, combustion blow-by from the engine enters through the heating joint into a heating passage of the carburetor to heat up the carburetor thus to prevent it from being frozen, then the blow-by being discharged through an output pipe tube from the carburetor to be reclaimed by an air filter.
