    摘要： A power semiconductor is provided. The power semiconductor includes a gate, a source, a silicon chip and a drain. The source includes a first copper particle layer and a first metal layer. The first copper particle layer covers the upper surface of the first metal layer. The silicon chip is bonded to the lower surface of the first metal layer. The drain is bonded to the lower surface of the silicon chip. The thickness of the first copper particle layer is greater than the thickness of the first metal layer. All copper mentioned are of large grain copper with size greater than 0.25 um.

    摘要： A rotation resetting device and an electronic apparatus are provided. The rotation resetting device includes a functional unit, a limiting block and an elastic unit. The functional unit includes a functional element and a supporting element connected to the functional element, wherein the supporting element includes a limiting gasket. The limiting block has an accommodating space with an opening and a taper chute extending downward from the opening. The elastic unit is located in the accommodating space and connected between the limiting block and the functional unit. The functional unit is movably disposed in the accommodating space and is capable of moving between an use position and a storage position relative to the opening. When the functional unit moves from the use position to the storage position, the limiting gasket abuts the taper chute, and rotates and slides downward along the taper chute while compressing the elastic unit.
