    • The structure of stacked integrated circuits includes a substrate, a lower integrated circuit, a plurality of wirings, an adhesive layer, and an upper integrated circuit. The substrate has a first surface formed with signal input terminals, and a second surface formed with signal output terminals. The lower integrated circuit has a first surface and a second surface. The first surface is adhered to the first surface of the substrate while the second surface is formed with a plurality of bonding pads. The wirings have first ends and second ends. The first ends are electrically connected to the bonding pads of the lower integrated circuit while the second ends are electrically connected to the signal input terminals of the substrate. The adhesive layer is coated on the second surface of the lower integrated circuit and includes adhesive agent and filling elements. The upper integrated circuit is stacked above the second surface of the lower integrated circuit with the adhesive layer inserted between the upper and lower integrated circuit. The lower integrated circuit is adhered to the upper integrated circuit by the adhesive agent. A predetermined gap is formed between the lower and upper integrated circuit by the filling elements. According to this structure, the wirings located under the lower integrated circuit are free from being pressed and damaged by the upper integrated circuit when stacking a plurality of integrated circuits. Thus, the stacking processes can be facilitated and the manufacturing costs can also be lowered.
    • 堆叠集成电路的结构包括基板,下部集成电路,多个布线,粘合层和上部集成电路。 衬底具有形成有信号输入端的第一表面和形成有信号输出端的第二表面。 下集成电路具有第一表面和第二表面。 第一表面粘附到基板的第一表面,而第二表面形成有多个接合焊盘。 布线具有第一端和第二端。 第一端电连接到下集成电路的接合焊盘,而第二端电连接到衬底的信号输入端。 粘合剂层涂覆在下部集成电路的第二表面上并且包括粘合剂和填充元件。 上集成电路堆叠在下集成电路的第二表面上方,粘合层插入在上下集成电路之间。 下集成电路通过粘合剂粘附到上集成电路。 通过填充元件在下集成电路和上集成电路之间形成预定的间隙。 根据该结构,当堆叠多个集成电路时,位于下部集成电路下方的配线不受上部集成电路的压制和损坏。 因此,可以促进堆叠处理,并且还可以降低制造成本。

    • A package structure of an image sensor is characterized in that an image sensing chip is directly packaged on a flexible circuit board by way of flip chip bonding. The package structure of an image sensor includes an image sensing chip, a flexible circuit board, and a transparent layer. A plurality of electrical circuits are formed on the image sensing chip. Each of the electrical circuits is formed with bonding pads. A flexible circuit board has an upper surface and a lower surface. Signal input terminals are formed on the lower surface and at positions corresponding to each of the bonding pads of the image sensing chip, respectively, for electrically connecting to the corresponding bonding pads of the image sensing chip. The signal input terminals are electrically connected to signal output terminals, respectively, for electrically connecting to the printed circuit board. The transparent layer is used for covering the upper surface of the flexible circuit board. The image sensing chip receives image signals via the transparent layer, transforms the image signals into electrical signals, and transmits the electrical signals from the flexible circuit board to the printed circuit board.
