摘要:
A thick cleaning composition, comprising a long-chain fatty acyl acidic amino acid ester; a fatty compound of fatty acid, fatty alcohol, fatty alcohol ether or polyol fatty acid ester; a surfactant; a solvent composed of water, lower alcohol, polyol and polyol ether; and further comprising a beautifying and cleaning adjuvant for skin, eyes, teeth and hair. The cleaning composition can achieve satisfactory thick appearance when used for cleaning skin and hair, and maintain stable viscosity at different temperatures. In use, the composition can be easily daubed, and foams quickly with good foaming quality.
摘要:
A combined packaged power semiconductor device includes flipped top source low-side MOSFET electrically connected to top surface of a die paddle, first metal interconnection plate connecting between bottom drain of a high-side MOSFET or top source of a flipped high-side MOSFET to bottom drain of the low-side MOSFET, and second metal interconnection plate stacked on top of the high-side MOSFET chip. The high-side, low-side MOSFET and the IC controller can be packaged three-dimensionally reducing the overall size of semiconductor devices and can maximize the chip's size within a package of the same size and improves the performance of the semiconductor devices. The top source of flipped low-side MOSFET is connected to the top surface of the die paddle and thus is grounded through the exposed bottom surface of die paddle, which simplifies the shape of exposed bottom surface of the die paddle and maximizes the area to facilitate heat dissipation.
