A power semiconductor including a gate, a source, a plurality of first long-strip source metal layer, a drain and a plurality of second long-strip drain metal layer is provided. The source includes a first copper particle layer and a first metal layer that covers the bottom surface of the first copper particle layer. The source is bonded to the first long-strip source metal layer via a first metal pillar. The drain includes a second copper particle layer and a second metal layer that covers the bottom surface of the second copper particle layer. The drain is bonded to the second long-strip drain metal layer via a second metal pillar. The thickness of the first copper particle layer and the second copper particle layer are 5 &#x3bc;m&#x2dc;100 &#x3bc;m. The first copper particle layer and the second copper particle layer are formed by plating and stacking a plurality of large-grain copper.

Power semiconductor

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.

An electronic device including a base, a display and a functional assembly is provided. The display is movably connected to the base and adapted to act between a lower position and an upper position relative to the base. The functional assembly is movably connected to the base and adapted to act between a first state and a second state relative to the base. When the display acts to the upper position from the lower position, the functional assembly acts to the second state from the first state, and when the functional assembly acts to the first state from the second state, the display acts to the lower position from the upper position.

Electronic device with elevating type display

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.
