Abstract: A semiconductor device includes a device layer, a semiconductor layer, a sensor element, a dielectric layer, a color filter layer, and a micro-lens. The semiconductor layer is over the device layer. The semiconductor layer has a plurality of microstructures thereon. Each of the microstructures has a substantially triangular cross-section. The sensor element is under the microstructures of the semiconductor layer and is configured to sense incident light. The dielectric layer is over the microstructures of the semiconductor layer. The color filter layer is over the dielectric layer. The micro-lens is over the color filter layer.

Abstract: A combinable nucleic acid pre-processing apparatus includes a sample transfer chamber transferring a sample from a sampling tube to a nucleic acid extraction kit, a nucleic acid extraction chamber performing a nucleic acid extraction of the sample in the nucleic acid extraction kit for obtaining a nucleic acid extract, an assay setup chamber preparing reagents and transferring reagents and the nucleic acid extract to an assay plate, and at least two bridging modules respectively disposed between the sample transfer chamber and the nucleic acid extraction chamber and between the nucleic acid extraction chamber and the assay setup chamber. The sample transfer chamber, the nucleic acid extraction chamber and the assay setup chamber are separated and operated independently. Three chambers are connected through the bridging modules, so the nucleic acid extraction kit can be sequentially moved in the sample transfer chamber, the nucleic acid extraction chamber and the assay setup chamber.

Abstract: A photo-detecting device includes a first semiconductor layer with a first dopant, a light-absorbing layer, a second semiconductor layer, and a semiconductor contact layer. The second semiconductor layer is located on the first semiconductor layer and has a first region and a second region, the light absorbing layer is located between the first semiconductor layer and the second semiconductor layer and has a third region and a fourth region, the semiconductor contact layer contacts the first region. The first region includes a second dopant and a third dopant, the second region includes second dopant, and the third region includes third dopant. The semiconductor contact layer has a first thickness greater than 50 ? and smaller than 1000 ?.

Abstract: A lamp for a light string has a socket, multiple electric cords, an insulating partition, a leaf spring and a bulb assembly. The electric cords are mounted in the socket and have electrodes. The insulating partition is mounted in the socket and has a cavity and at least one stopper formed in the cavity. The leaf spring is mounted in the insulating partition, is V shaped, is held in place by the stopper and protrudes through a top of the insulating partition to selectively and respectively contact the electrodes. The bulb assembly is removably plugged into the socket and has a separator. The separator pushes the leaf spring into the insulating partition to stop the leaf spring from contacting the electrodes. When the bulb assembly is removed from the socket, the leaf spring returns to an original shape by resilience to contact the electrodes.

Abstract: A decorative light string has a power connector, at least one lightening unit and a rectifier. The lightening unit is electrically connected to the power connector and has an incandescent bulb set and an LED set. The incandescent bulb set has a primary wire and multiple incandescent bulbs. The LED set has a secondary wire and multiple LEDs. The incandescent bulbs and LEDs are respectively electrically connected to the primary and the secondary wire. The secondary wire is electrically connected and intertwined with primary wire. At least one of the incandescent bulbs of the incandescent bulb set is placed between each two of the LEDs. The rectifier is electrically connected the power connector and each LED set in series. The decorative light string has an advantage of preventing snow to veil LEDs by the heat from the incandescent bulbs when used in the snows.
