Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: A semiconductor structure includes a substrate, and an active device and a passive device over the substrate. The active device is disposed in a first region of the substrate, and the passive device is disposed in a second region of the substrate. The semiconductor structure further includes a shielding structure and a passivation layer. The shielding structure includes a barrier layer and a ceiling layer. The barrier layer is on the passive device and the active device, and the ceiling layer is on the barrier layer. The passivation layer is under the barrier layer and covers a top surface of the passive device. An air cavity is defined by sidewalls of the barrier layer, a bottom surface of the ceiling layer, and the substrate.

Abstract: A waterproof and heat-dissipating module mounted on an electronic device includes a housing structure, a compartment structure, and a fan. A first ventilation hole, a second ventilation hole, a first drainage holes, and a second drainage holes are formed on the housing structure. The compartment structure is disposed inside the housing structure and for partitioning an inside space of the housing structure off that includes an inhaling chamber, a fan room, an accommodated space, and an exhausting chamber. The fan is disposed inside the fan room so that airflow is guided from the first ventilation hole to the second ventilation hole via the inhaling chamber, the fan room, the accommodated space, and the exhausting chamber so as to dissipate heat from circuit boards disposed inside the accommodated space away.
