    Abstract: A single-chip common-drain JFET device comprises a drain, two gates and two source arranged such that two common-drain JFETs are formed therewith. Due to the two JFETs merged within a single chip, no wire bonding connection is needed therebetween, thereby without parasitic inductance and resistance caused by bonding wire, and therefore improving the performance and reducing the package cost. The single-chip common-drain JFET device may be applied in buck converter, boost converter, inverting converter, switch, and two-step DC-to-DC converter to improve their performance and efficiency. Alternative single-chip common-drain JFET devices are also provided for current sense or proportional current generation.

    Abstract: Disclosed herein is a multi-layer coated product comprising a substrate, and a multi-layer coating including an undercoat and a topcoat which are formed on the substrate in sequence, have alcohol resistance, and are in a different color from each other, wherein the multi-layer coating further includes an intermediate coat having no alcohol resistance between the undercoat and the topcoat. Also disclosed herein is a method for preparing the multi-layer coated product. Since the intermediate coat of the multi-layer coated product has no alcohol resistance, when the intermediate coat and topcoat on the backlight part is removed by the laser engraving, it is sufficient that the laser intensity is controlled to be higher than the laser intensity required for completely removing the topcoat and lower than the laser intensity that affects the undercoat, the time required for determining the laser intensity and scrubbing can be shortened, and thereby the production efficiency of said multi-layer coated product can be improved.
