Abstract: A microelectromechanical system (MEMS) structure and method of forming the MEMS device, including forming a first metallization structure over a complementary metal-oxide-semiconductor (CMOS) wafer, where the first metallization structure includes a first sacrificial oxide layer and a first metal contact pad. A second metallization structure is formed over a MEMS wafer, where the second metallization structure includes a second sacrificial oxide layer and a second metal contact pad. The first metallization structure and second metallization structure are then bonded together. After the first metallization structure and second metallization structure are bonded together, patterning and etching the MEMS wafer to form a MEMS element over the second sacrificial oxide layer. After the MEMS element is formed, removing the first sacrificial oxide layer and second sacrificial oxide layer to allow the MEMS element to move freely about an axis.

Abstract: A shelving structure may include a predetermined number of shelf boards, rear plates, connecting members, and frame members. The shelf board is a rectangular board with two expanded side edges. The rear plate is a hexagonal plate with corners modified into arc-shaped inward recesses and with U-shaped slots extending inwards in the middle of the recesses. The U-shaped slot has continuous undulating bounding edges on both of its sides. The connecting member has two clamping planes linked by a base. The frame member has three equally distributed holding slots extending through both ends. Each outer surface between two neighboring holding slots of the connecting member has a recessed strip with regularly spaced extension plates for installing additional components. The shelving structure can be readily installed or uninstalled and can be modified or rearranged according to space restraint or other requirements.

Abstract: A combination rack structure includes a predetermined number of support plates, connecting strips and side frames. Each of the support plates has a rectangular shape. Each of the connecting strips is provided with three holding grooves each longitudinally extended through each of the connecting strips. Each of the connecting strips has a periphery provided with elongate recessed portions each located between any two of the holding grooves. Each of the recessed portions is provided with a plurality of extensions which are perpendicular to an axial direction of each of the recessed portions and are spaced from each other with a proper interval. The extensions are used for holding and resting. Each of the side frames is bent to have a hexagonal shape. The support plates are combined with the connecting strips to construct a hexagonal rack.
