  • Publication number: 20250081668
    Abstract: A chip package includes a semiconductor substrate, an anti-reflection layer, and a metal multi-layer. The semiconductor substrate has an optical sensing area. The anti-reflection layer is located on the semiconductor substrate. The metal multi-layer is located on and in contact with the anti-reflection layer. The metal multi-layer includes a redistribution line and two probe pads. Two ends of the redistribution line respectively extend to the two probe pads. The redistribution line is located in the optical sensing area, and the two probe pads are located outside the optical sensing area. The orthographic projection area of the redistribution line in the optical sensing area is less than 1% of the area of the optical sensing area.

  • Publication number: 20250054849
    Abstract: A chip package is provided. The chip package includes a device substrate, a first redistribution layer (RDL), a carrier base, and at least one conductive connection structure. The device substrate has at least one first through-via opening extending from the backside surface of the device substrate to the active surface of the device substrate. The first RDL is disposed on the backside surface of the device substrate and extends in the first through-via opening. The carrier base carries the device substrate, and has a first surface facing the backside surface of the device substrate and a second surface opposite the first surface. The conductive connection structure is disposed on the second surface of the carrier base and is electrically connected to the first RDL.

  • Publication number: 20200050367
    Abstract: A storage system capable of executing a managing operation based on timestamp and a management method are disclosed. The storage system includes a control unit and a memory unit connected to the control unit. The management method includes steps of: (a) issuing a control instruction comprising a timestamp to the control unit, wherein when the control unit receives the control instruction, the control unit starts to control the memory unit and accesses at least one storage space from the memory unit; and (b) sequentially counting plural numbers of instruction operations in plural time intervals, wherein the plural numbers of the instruction operations in each of the plural time intervals are stored in the at least one storage space. Since the peak period and the off-peak period of the storage system can be counted based on the timestamp, it facilitates the storage system to set a triggering time to execute a background operation.

  • Patent number: 9769893
    Abstract: A light-emitting device and a control method are provided. The light-emitting device is applied to a memory module. The light-emitting device includes at least one memory module board, at least one light-emitting board and an application program unit. The at least one memory module board is connected with a host. Each light-emitting board includes plural light-emitting units and a control unit. The control unit controls a lighting mode of the plural light-emitting units. The control unit is electrically connected with the host through the corresponding memory module board. The application program unit generates a control signal. The control signal is transmitted to the control unit of each light-emitting board through the host. The control unit controls the corresponding light-emitting units according to the control signal.
