Abstract: A stacked integrated circuit (IC) device and a method are disclosed. The stacked IC device includes a first semiconductor element. The first substrate includes a dielectric block in the first substrate; and a plurality of first conductive features formed in first inter-metal dielectric layers over the first substrate. The stacked IC device also includes a second semiconductor element bonded on the first semiconductor element. The second semiconductor element includes a second substrate and a plurality of second conductive features formed in second inter-metal dielectric layers over the second substrate. The stacked IC device also includes a conductive deep-interconnection-plug coupled between the first conductive features and the second conductive features. The conductive deep-interconnection-plug is isolated by dielectric block, the first inter-metal-dielectric layers and the second inter-metal-dielectric layers.

Abstract: A function-switching type linking apparatus includes a USB linking interface, a data transmission unit, a charging unit and a control unit. The USB linking interface receives an external signal and outputs to the control unit. Based on the external signal, the control unit determines whether to execute the data transmission operation or the charging operation. The function-switching type linking apparatus of the present invention can be based on the external signal to switch the data transmission operation or the charging operation, and extends the life of the rechargeable battery in the portable information product.
