摘要:
A semiconductor device includes a package hermetically sealed with a chalcogenide-based glass sealing agent. A semiconductor element is housed within the package, and the respective electrodes of the semiconductor element are connected through bonding wires to leads extending to the outside of the package.
摘要:
The present invention relates to a package adapted to house an electronic device, such as a semiconductor integrated circuit. The package components are comprised of aluminum or an aluminum based alloy. At least a portion of the surfaces of the package components are anodized to enhance corrosion resistance and increase bond strength. The aluminum based packages are characterized by lighter weight than copper based packages and better thermal conductivity than plastic based packages.
摘要:
A semiconductor device wherein a coating film which is made of a polyimide resin or a polyimide isoindoloquinazolinedione resin and which is at least 10 .mu.m thick is disposed on at least an active region of a semiconductor substrate, and the resultant semiconductor substrate is encapsulated in a ceramic package. The semiconductor device has troubles relieved conspicuously, the troubles being ascribable to alpha-rays which come flying from impurities contained in the material of the package.
摘要:
An integrated circuit package uses an encapsulant frame which prevents the encapsulant used to seal the integrated circuit chip from the ambient atmosphere from flowing to unwanted areas and to permit the encapsulant to be deposited with a controllable depth.
摘要:
A semiconductor device including a semiconductor chip, a leadless chip carrier to one side of which the chip is adhered, and a cap which seals the leadless chip carrier to protect the semiconductor chip. A heat sinking plate (21a or 21b) which is electrically connected to the semiconductor chip (8) is provided on the opposite side of the leadless chip carrier (1).
摘要:
A semiconductor hermetic package for semiconductor device comprises base, sidewall and cover members. Signals can be coupled between the enclosed devices and external devices by coupling means including conductive regions disposed in and through the package. Light pipes or conductive tracks and paths extending through the package can be used to couple the signals. A portion of the package can function as a grading resistance.
摘要:
A chip carrier with multiple through hole vias in its hermetic sealing lid. One or more chips is mounted on the inner surface of that lid. The lid contains multiple through vias, and the semiconductor chip on the inner surface of the lid is bonded to the vias in the lid by TAB strips or (optionally) by wire bonds. The vias in the lid connect these leads through to contacts on the outer surface of the package. These contacts can than be connected to (using interconnect structures such as TAB strips, or printed wiring boards, or discretionary wiring), to provide circuit interconnection. Preferably low-power-dissipation chips are mounted on the inner surface of the lid in this fashion, with higher-power-dissipation chips mounted on the bottom surface of the chip cavity.
摘要:
An improved integrated circuit package of the MLCP type suitable for use both at high operating frequencies and with chips dissipating large amounts of power. Electric power supplying wirings and signal transmitting wirings are disposed on entirely separate surfaces, the power transmitting wirings being formed on entire peripheries of respective, dedicated ceramic plates. Termination resistors for the signal wirings though are formed on the same ceramic plates which contain the power supplying wirings.
摘要:
A semiconductor device in which a heat-radiator is bonded by a resin film to a metal plate constituting a part of a package is disclosed. Gold plating layers are employed in bonding pads, outer leads and the die bonding portion of the package. However, from the surface of the metal plate to which the resin film is adhered, the gold plating layer is removed or excluded, and the resin film is adhered to an underlying nickel plating layer.
摘要:
A semiconductor chip carrier having a ceramic base with a cavity for carrying a semiconductor chip and a cap for sealing the chip within the cavity. The base has a metallization pattern covering the chip contacts on the base and an outer contact castellated ring providing for the flow of excess solder away from the contact area.
