Abstract: An integrated circuit package including electrically floating metal lines and a method of forming are provided. The integrated circuit package may include integrated circuit dies, an encapsulant around the integrated circuit dies, a redistribution structure on the encapsulant, a first electrically floating metal line disposed on the redistribution structure, a first electrical component connected to the redistribution structure, and an underfill between the first electrical component and the redistribution structure. A first opening in the underfill may expose a top surface of the first electrically floating metal line.

Abstract: A semiconductor structure includes a functional die, a dummy die, a redistribution structure, a seal ring and an alignment mark. The dummy die is electrically isolated from the functional die. The redistribution structure is disposed over and electrically connected to the functional die. The seal ring is disposed over the dummy die. The alignment mark is between the seal ring and the redistribution structure, wherein the alignment mark is electrically isolated from the dummy die, the redistribution structure and the seal ring. The insulating layer encapsulates the functional die and the dummy die.

Abstract: A lens device includes a control unit, an objective lens, an image sensor, a light source, a detecting unit, and a tube assembly. The tube assembly includes a guide barrel, an outer tube, and a lens holder. The guide barrel is disposed on the control unit. The outer tube includes a tube body that is rotatably sleeve don the guide barrel, and a guiding portion. The lens holder includes a holder body having a set of projections driven by the guiding portion. The image sensor is electrically coupled to the control unit. The objective lens is optically aligned with the image sensor. The light source is coupled electrically to the control unit. The detecting unit generates a detector output indicating angular orientation of the outer tube. The control unit is responsive to the detector output to control intensity of light outputted by the light source.

Abstract: A lens device includes a control unit, an objective lens, an image sensor, a light source, a detecting unit, and a tube assembly. The tube assembly includes a guide barrel, an outer tube, and a lens holder. The guide barrel is disposed on the control unit and confines a barrel hole that extends along a barrel axis. The outer tube includes a tube body that is rotatably sleeved on the guide barrel, and a guiding portion. The lens holder includes a holder body having a set of projections driven by the guiding portion. The image sensor is electrically coupled to the control unit.
