  • Patent number: 8803301
    Abstract: A semiconductor package may include a substrate, a semiconductor chip disposed on the substrate, a communication terminal and a static electricity inducing terminal connected to a ground. The package may include a first sealant that comprises a voltage sensitive material and that covers the semiconductor chip and a static electricity blocking layer that provides a conductive pathway from the first sealant to only the static electric inducing terminal. The static electricity blocking layer may prevent the communication terminal from being electrically connected to the first sealant. If a buildup of charge is applied to the device, the first sealant may become polarized and/or conductive. The extra voltage may travel through the first sealant to the static electricity inducing terminal via an opening in the static electricity blocking layer. The semiconductor chip and the communication terminal may not be affected by the extra charge.

    Abstract: A semiconductor chip package includes an IC chip and a tape circuit substrate. The tape circuit substrate has a base film and a plurality of beam leads formed on the base film. One end portion of each beam lead extends from the base film, and the extended portion has a wavy portion. The wavy portion can be, for example, semicircular shaped, an S-shaped, or a zigzag shaped. The IC chip has chip pads formed on a top surface thereof. The beam lead is bonded to the chip pad through an inner lead bonding (ILB) process. During the ILB process, the wavy portion disperses the stress produced in the beam lead. Therefore, a crack or a break of the beam lead due to the stress can be effectively prevented, improving interconnection reliability between the IC chip and the tape circuit substrate.
