Abstract: Provided are a passivation layer for forming a semiconductor bonding structure, a sputtering target making the same, a semiconductor bonding structure and a semiconductor bonding process. The passivation layer is formed on a bonding substrate by sputtering the sputtering target; the passivation layer and the sputtering target comprise a first metal, a second metal or a combination thereof. The bonding substrate comprises a third metal. Based on a total atom number of the surface of the passivation layer, O content of the surface of the passivation layer is less than 30 at %; the third metal content of the surface of the passivation layer is less than or equal to 10 at %. The passivation layer has a polycrystalline structure. The semiconductor bonding structure sequentially comprises a first bonding substrate, a bonding layer and a second bonding substrate: the bonding layer is mainly formed by the passivation layer and the third metal.

Abstract: A UV light sterilization device includes a main body with an accommodation space defined therein for a predetermined item to be placed in a horizontal direction, a power supply module mounted in one side plate of the main body and providing an electrical connection port, and a UV lamp set with a drive control circuit assembled on the bottom side of the top cover of the main body and electrically connected to the electrical connection port, the drive control circuit having a plurality of evenly distributed UV LED chips for downwardly irradiating the surface of the predetermined item that is placed in the main body.

Abstract: A dual-use footrest is disclosed. The dual-use footrest comprises a bottom frame and a flip frame. The bottom frame includes a shaft part disposed at a side of the two side plates, and a support disposed a side of the shaft part, and the flip frame includes a shaft coupling part disposed at a side of the two side frames and pivotally connected to the shaft part, and a pedal part disposed on a side of the shaft coupling part. When the back surface of the flip frame is abutted on the bottom frame, the user with the sitting posture can step on the pedal part; and, when the flip frame is outwardly flipped about the shaft coupling part and the shaft part, to abut on the support of the bottom frame by the top surface thereof, the user with the standing posture can step on the footrest.
