    摘要: A chip package includes a high voltage withstanding substrate and a device chip. The high voltage withstanding substrate has a main body, a functional layer, and a grounding layer. The main body has a top surface, a bottom surface opposite the top surface, a through hole through the top surface and the bottom surface, and a sidewall surrounding the through hole. The functional layer is located on the top surface. The grounding layer covers the bottom surface and the sidewall. The device chip is located on the functional layer, and has a grounding pad that faces the main body. The grounding pad is electrically connected to the grounding layer in the through hole.

    摘要: A method for forming a sensing device includes providing a first substrate. The first substrate has a first surface and a second surface opposite thereto. A sensing region is adjacent to the first surface. A temporary cover plate is provided on the second surface to cover the sensing region. The method also includes forming a redistribution layer on the second surface and electrically connected to the sensing region. The method further includes removing the temporary cover plate after the formation of the redistribution layer. The first substrate is bonded to a second substrate and a cover plate after the removal of the temporary cover plate so that the first substrate is positioned between the second substrate and the cover plate. In addition, the method includes filling an encapsulating layer between the second substrate and the cover plate to surround the first substrate.

    摘要: A method for manufacturing a semiconductor structure includes the following steps. A first carrier is adhered to a first surface of a wafer by a first temporary bonding layer. A second surface of the wafer facing away from the first carrier is etched to form at least one through hole and at least one trench, in which a conductive pad of the wafer is exposed through the through hole. An isolation layer is formed on the second surface of the wafer, a sidewall of the through hole, and a sidewall of the trench. A second carrier is adhered to the second surface of the wafer by a second temporary bonding layer, and thus the through hole and the trench are covered by the second carrier. The first carrier and the first temporary bonding layer are removed.

    摘要: A manufacturing method of a semiconductor structure includes the following steps. A patterned photoresist layer is formed on a wafer of the wafer structure. The wafer is etched, such that channels are formed in the wafer, and a protection layer of the wafer structure is exposed through the channels. The protection layer is etched, such that openings aligned with the channels are formed in the protection layer. Landing pads in the protection layer are respectively exposed through the openings and the channels, and the caliber of each of the openings is gradually increased toward the corresponding channel. Side surfaces of the wafer surrounding the channels are etched, such that the channels are expanded to respectively form hollow regions. The caliber of the hollow region is gradually decreased toward the opening, and the caliber of the opening is smaller than that of the hollow region.
