Abstract: A semiconductor device structure is provided. The semiconductor device structure includes a chip structure including a substrate and a wiring structure over a first surface of the substrate. The semiconductor device structure includes a first seed layer over the wiring structure, a first inner wall of the first enlarged portion, and a second inner wall of the neck portion. The semiconductor device structure includes a second seed layer over a second surface of the substrate, a third inner wall of the second enlarged portion, and the first seed layer over the second inner wall of the neck portion. The second seed layer is in direct contact with the first seed layer.

Abstract: A display device includes a first substrate, a light-emitting element, a light conversion layer, and a color filter layer. The light-emitting element is disposed on the first substrate. The light conversion layer is disposed on the light-emitting element. In addition, the color filter layer is overlapped the light-emitting element and the light conversion layer.

Abstract: Integrated fan-out packages and methods of forming the same are disclosed. An integrated fan-out package includes two dies, an encapsulant, a first metal line and a plurality of dummy vias. The encapsulant is disposed between the two dies. The first metal line is disposed over the two dies and the encapsulant, and electrically connected to the two dies. The plurality of dummy vias is disposed over the encapsulant and aside the first metal line.

Abstract: A facial expression operation method includes capturing images using a camera device of an electronic device. A face area of the user exists in the images is determined by comparing the images with face image samples stored in a storage device. Feature values of the face area are calculated when the face area exists in the images. A facial expression is determined by comparing the feature values of the face area and the feature values of the face image samples. The electronic device is operated automatically to perform a corresponding function according to the facial expression.
