Abstract: The present disclosure provides a semiconductor device. The semiconductor device includes a first device and a second device disposed adjacent to the first device; a conductive pillar disposed adjacent to the first device or the second device; a molding surrounding the first device, the second device and the conductive pillar; and a redistribution layer (RDL) over the first device, the second device, the molding and the conductive pillar, wherein the RDL electrically connects the first device to the second device and includes an opening penetrating the RDL and exposing a sensing area over the first device.

Abstract: A fan includes a hub and a plurality of fan blades. The hub has an axle center. The fan blades are disposed around the hub. Each of the fan blades has a bent portion, and the bent portions of the fan blades are extended along a surrounding direction surrounding the axle center. The hub is welded with the bent portion of each of the fan blades along the surrounding direction. As a result, the number of fan blades is maximized, the strength is simultaneously ensured to be enough, and the advantages of effectively enhancing the fan characteristics are achieved.

Abstract: A fan includes a hub and a blade assembly. The hub has a central portion and an extension portion. The extension portion is extended outwardly from a peripheral edge of the central portion. The blade assembly includes a plurality of blades. Each blade has a leading edge, each of the leading edges is an end point of each blade that is most close to the central portion. The blades are disposed around the hub. At least a part of the leading edges of the blades are connected to the extension portion, and distances between a center of the central portion and the leading edges of at least two blades are different. Therefore, the factors of fan and the quality of voice could be enhanced, and the multi-frequencies noise could be avoided during operation.

Abstract: An in-mold vibratile injection compression molding method and molding apparatus thereof are described. While performing a filling stage, a first piezoelectric actuator and a second piezoelectric actuator are use to vibrate the molding material along at least two directions for precisely filling the molding material into the micro-structure by adjusting the filling flow velocity of the molding material associated with the proper molding material temperature and by maintaining a molding material temperature of a skin solidified layer in the cavity between a glass transition temperature and a melting temperature in order to avoid the form error, to increase the groove filling rate and to improve the residual stress.
