Abstract: A semiconductor structure includes a first interposer; a second interposer laterally adjacent to the first interposer, where the second interposer is spaced apart from the first interposer; and a first die attached to a first side of the first interposer and attached to a first side of the second interposer, where the first side of the first interposer and the first side of the second interposer face the first die.

Abstract: A dental floss holder includes a main body, a retractable member movably mounted on a first end of the main body, a rotation member rotatably mounted in the main body and having a first end engaged with the retractable member to move the retractable member axially relative to the main body by rotation of the rotation member, and a control member rotatably mounted on a second end of the main body and engaged with a second end of the rotation member so as to rotate the rotation member. Thus, the dental floss holder is operated to stretch or release the dental floss easily and conveniently, thereby facilitating the user mounting or replacing the dental floss.

Abstract: A switch device includes a male assembly, and a female assembly. The male assembly includes a first fixing seat, a first operation socket, a first locking seat, and a retractable rod. The female assembly includes a second fixing seat, a second operation socket, and a second locking seat. Thus, the male assembly can be detached from the female assembly rapidly, thereby facilitating the user operating the switch device to open the door of the refrigerator. In addition, the user only needs to press the door of the refrigerator so as to open the door of the refrigerator easily and conveniently, thereby facilitating the user opening the door of the refrigerator.

Abstract: A timing lock device for a faucet includes a valve seat, a top cover, a locking washer, a relief rod, a locking valve shaft, and a compression spring. In use, the relief rod may be used to release the water pressure in the pressure storage chamber of the top cover. Then, the locking washer may be moved upward by the locking valve shaft, so that the water may flow outward. When not in use, the water may flow through the return through hole of the top cover into the pressure storage chamber. Thus, the water flow may be stopped automatically by the restoring force of the compression spring and the water pressure in the pressure storage chamber, thereby saving the manual work, and thereby achieving an excellent leakproof effect.
