Abstract: Semiconductor dies of a semiconductor die package are directly bonded, and a top metal region may be formed over the semiconductor dies. A plurality of conductive terminals may be formed over the top metal region. The conductive terminals are formed of copper (Cu) or another material that enables low-temperature deposition process techniques, such as electroplating, to be used to form the conductive terminal. In this way, the conductive terminals of the semiconductor die packages described herein may be formed at a relatively low temperature. This reduces the likelihood of thermal deformation of semiconductor dies in the semiconductor die packages. The reduced thermal deformation reduces the likelihood of warpage, breakage, and/or other types of damage to the semiconductor dies of the semiconductor die packages, which may increase performance and/or increase yield of semiconductor die packages.

Abstract: A bottom-emission light-emitting diode (LED) display includes a transparent substrate, a plurality of LEDs bonded on the substrate, a packaging layer formed on the substrate to cover the LEDs, and a reflecting layer formed on the packaging layer to reflect light emitted by the plurality of LEDs. The reflecting layer has a non-smooth shape or the packaging layer has different refractivities.

Abstract: A chip package structure is provided. The chip package structure includes a chip. The chip package structure includes a conductive ring-like structure over and electrically insulated from the chip. The conductive ring-like structure surrounds a central region of the chip. The chip package structure includes a first solder structure over the conductive ring-like structure.

Abstract: An interactive education system includes a storage, an output device, a processor, an input device and a recognition device. The processor controls the output device to produce voice based on a hint on a target answer stored in the storage. The recognition device generates a response through performing speech recognition on input data generated by the input device from voice of a user. The processor controls the output device to produce voice based on whether the response matches the target answer or any relevant characteristic. Depending on a count of consecutive occurrences of a failed event, the processor controls the output device to produce voice based on another hint or the target answer.

Abstract: An illuminating cosmetic applicator is revealed. The illuminating cosmetic applicator includes a cosmetic applicator part, a connector, and a lighting unit. The cosmetic applicator part is made from a transparent material. One end of the connector is connected to the cosmetic applicator part while the other end thereof is mounted with the lighting unit. The lighting unit consists of a light gathering cover mounted in a housing, and a light emitting element in the light gathering cover. Batteries are received in the housing. Moreover, a groove mounted with a switch is arranged at the housing. A block is connected to the inner side of the switch. Thereby light is emitted through the cosmetic applicator part while applying cosmetics in a dark place. Furthermore, the lighting unit can be separated with the cosmetic applicator part and used for illumination independently. The illuminating cosmetic applicator has more practical value.

Abstract: A miniature stacked glass lens module is disclosed. The miniature stacked glass lens module includes at least one stacked optical glass lens element, a lens holder and other optical element. The stacked optical glass lens element is formed by cutting along alignment notches on a glued and stacked optical glass lens array. Then the stacked optical glass lens element and other optical element are mounted into the lens holder to form a miniature stacked glass lens module. Thereby the precise alignment of the optical axis of the lens in the lens module can be achieved. The manufacturing processes of the lens module can be simplified dramatically and the manufacturing cost is reduced significantly.
