    摘要: A substrate for packaging semiconductor chips is provided which is structured with conductors having opposite ends terminating in a mounting surface and intermediate portions extending beneath the surface. The ends of the conductors are arranged in repeating patterns longitudinally along the substrate separated by orthogonal strips free of conductor ends to allow for dense surface wiring. The repeating patterns are arranged to allow for chip mounting sites having sufficient spacing to allow for surface wiring. In this way chips in the same and repeat pattern can be connected by personalized surface wiring and preset substrate conductors.

    摘要: A nodular metal paste (42) is used to temporarily attach the bumps (34) on a semiconductor die (32) to a substrate (38). The spherical nodules (44) composing the metal paste are dispensed onto contact pads (40) on the substrate, and then heated until they partially melt. The partial liquid region permits bonding of the individual metal nodules to the contact pads and to adjacent nodules. Subsequently, a bumped die is placed over the nodules and heated to a minimum temperature required to partially remelt to form a local tack joint. Because the metallurgical contact area between the paste nodules and the bumps is minimized, electrical contact can be sustained with a small cross-sectional area of connected material to create an electrically sound but physically weak link between die and the substrate. Once connected to the substrate, the die may be tested and burned-in, and removed afterwards with little damage to the bumps.

    摘要: A method of making an aperture of a predetermined shape into a dielectric substrate which will lockingly receive a deformable contact pin. It includes providing a dielectric material which shrinks in response to a heat treatment by an amount which is different in one direction from that in another direction, and which irreversibly changes dimensions in its two orthogonal directions in proportion to this difference. An aperture is formed in such a material, in a direction normal to the plane of the two orthogonal directions and the material is subjected to a heat treatment that causes a differential shrinkage in the aperture and a change in the shape of the aperture. A deformable contact pin is then forced into a locking position in the aperture. By using such a method to lock a contact pin in close proximity to a conductive line extending across the substrate or by having the aperture and the pin extend through the substrate, electrical circuits on one side of the substrate can be contacted through a contact pin on the opposite side of the substrate.

    摘要: Flip-chip is fast becoming the mounting method of choice in the semiconductor industry for dice having a high number of contacts. Since many applications require known-good-die, these flip-chip semiconductor dice must be tested and burned-in. By testing and burning-in the semiconductor wafers prior to solder bumping, the probe tips (42, 44, 46 & 48) can contact the hard planar surface of the under-bump-metallurgy (40) on each bonding pad (14) for easier and more reliable contact and hence test results. The probe tips can be either of an array (42 & 44) or cantilevered needle (46 & 48) type. Blunt probe tips (42 & 48) are well-suited to making contact on the shoulder of each bonding pad of each semiconductor die, while sharp probe tips (44 & 46) are preferable for contacting the center of each bonding pad. Solder bumping is performed post-testing.

    摘要: A method and apparatus for depositing the material onto a substrate is provided. The apparatus includes a mesh member which has impregnated therein the material which is to be vapor deposited. The mesh member with the material thereon is heated to vaporize the material and the vaporized material is then deposited onto the desired substrate. Preferably the material that is deposited is maintained in a crucible having an opening and the mesh member is disposed over the opening. The material in the crucible is vaporized and condensed onto the mesh member, and the condensed material wicks through the mesh member and then revaporizes from the top of the mesh member and is deposited onto the substrates.

    摘要: The coating of a conductor pattern on dielectric green sheets to a common edge thereof with stacking or superimpositioning together of a plurality of sheets to enclose the conductor pattern followed by sintering, with the edge side of the fired body having the exposed end terminations becoming the actual face of the body on which a semiconductor device is mounted in electrical circuit connection to respective ones of the common end terminations of the conductor runs. The conductor runs are returned through the body to the active face of the body to position the opposite or distal ends of the conductors thereat, in an increased spaced relationship of the distal conductor terminations. For external connection, terminal pins may be embedded in the fired body for connection at adjacent and to the distal conductor termination, with the pins projecting therefrom.
