Abstract: A package structure including a semiconductor die, a redistribution circuit structure and an electronic device is provided. The semiconductor die is laterally encapsulated by an insulating encapsulation. The redistribution circuit structure is disposed on the semiconductor die and the insulating encapsulation. The redistribution circuit structure includes a colored dielectric layer, inter-dielectric layers and redistribution conductive layers embedded in the inter-dielectric layers. The electronic device is disposed over the colored dielectric layer and electrically connected to the redistribution circuit structure.

Abstract: A method of forming a semiconductor device is provided. The method includes forming a first film over an active region of a first side of a semiconductor substrate and a second film over a second side of the semiconductor substrate opposing to the first side of the semiconductor substrate; applying a chemical mechanical polishing to remove at least a portion of the second film; after the chemical mechanical polishing, forming a photoresist layer over the first film; and patterning the photoresist layer using an extreme ultraviolet radiation.

Abstract: A liquid lens chip, a driving apparatus and a driving method thereof are provided. The driving apparatus includes a carrier and a driver. The carrier is configured to carry a liquid lens and has a plurality of electrode pairs in contact with the liquid lens. The driver provides a periodic first driving signal to a selected electrode pair of the electrode pairs during a first time period according to a scan control signal to change a shape of the liquid lens. The driver further provides a periodic second driving signal to an opposite electrode pair opposite to the selected electrode pair during a second time period to recover the shape of the liquid lens which has been changed during the first time period.
