  • Patent number: 6593662
    Abstract: A stacked-die package structure comprises a carrier, dies, spacers, adhesive layers, conductive lines, a mold compound, and solder balls. The carrier has an upper surface and a back surface opposite to the upper surface. The dies substantially having the same sizes are stacked one by one on the upper surface of the carrier, and a number of bonding pads are located around each die. The spacers are located between two adjacent dies. Adhesive layers located between the spacers, the dies, and the carrier for adhering layers therebetween. The conducting lines are respectively electrically connected between each of the bonding pads of the dies and the carrier. And the mold compound is formed over the upper surface of the carrier, for encapsulating the spacers, the dies and the adhesive layers. A substrate with solder balls or a lead frame having pins is suitable for serving as the carrier.

  • Patent number: 6476469
    Abstract: A quad flat non-leaded package structure for housing a sensor. The package includes a die pad, a plurality of leads, a die, a plurality of bonding wires, a packaging plastic body and a lid cover. A plurality of supporters are formed near the edges on the backside of the die pad. The plurality of leads is positioned at a well-defined distance away from the four sides of the die pad. The packaging plastic body is formed on the upper surface near the peripheral section of the leads. The space between the die pad and the leads is filled by the packaging plastic material but the bottom section of the leads and the bottom section of the supporters on the backside of the die pad are exposed. The die is attached to the upper surface of the die pad and is electrically connected to the leads using the bonding wires. The lid cover is placed over the packaging plastic body.

  • Publication number: 20020060358
    Abstract: The present invention provides a package comprising a lead frame, which has a die pad and a plurality of leads located at the peripheral of the die pad. An image sensor chip has an active surface and a corresponding back surface. A plurality of bonding pads are on the active surface. A plurality of leads are electrically connected from the bonding pads to the inner leads. The image sensor chip, the die pads and the inner leads are encapsulated with a transparent molding material. A cavity is formed on a surface of the transparent molding material corresponding to the active surface. The area of the cavity, which is large enough just to cover the chip of the image sensor, has a smooth surface after a polishing process.
