摘要:
A semiconductor device package includes a die, a package encapsulating at least a portion of the die, and a plurality of leads. Each lead of the plurality includes an external portion. The external portion of each lead is substantially planar and extends outward from a bottom edge of the package. The external portion of each lead may be oriented in a plane that is substantially parallel to a plane within which the die is located. A semiconductor device including these features may be part of an assembly that also includes an alignment device for orienting the semiconductor device package in nonparallel relation to a substrate.

A fabrication substrate for use in fabricating integrated circuits and other electronic devices includes a substrate that comprises semiconductor material, as well as a support structure on an active surface of the substrate. The support structure is located at or adjacent to an entire outer peripheral edge of the substrate. The support structure may be configured as a ring-like element or as a member which substantially covers an active surface of the semiconductor substrate and forms a protective structure over each semiconductor device carried by the active surface.

A method for fabricating semiconductor components such as printed circuit boards, multi chip modules, chip scale packages, and test carriers is provided. The method includes providing a substrate having a blanket deposited conductive layer thereon. Using a laser machining process, grooves are formed in the conductive layer to define patterns of conductors on the substrate. The conductors can be formed with a desired size and spacing, and can include features such as bond pads, conductive vias, and external ball contacts. In addition, selected conductors can be configured as co-planar ground or voltage traces, for adjusting impedance values in other conductors configured as signal traces.

Microelectronic devices, methods for packaging microelectronic devices, and methods for forming interconnects in microelectronic devices are disclosed herein. In one embodiment, a method comprises providing a microelectronic substrate having a front side and a backside. The substrate has a microelectronic die including an integrated circuit and a terminal operatively coupled to the integrated circuit. The method also includes forming a passage at least partially through the substrate and having an opening at the front side and/or backside of the substrate. The method further includes sealing the opening with a conductive cap that closes one end of the passage while another end of the passage remains open. The method then includes filling the passage with a conductive material.

An insulative coating for an aperture of a semiconductor device component includes a plurality of adjacent, mutually adhered regions. The adjacent, mutually adhered regions may be formed by programmed material consolidation processes, such as stereolithography. Such an insulative coating may electrically isolate conductive features, such as conductive vias, from the substrate of a semiconductor device component.
摘要:
A method and apparatus for applying packaging material to workpieces, with a high degree of precision, and resulting articles. A machine vision system including at least one camera is operably associated with a computer controlling a system for application of material so that the system may recognize the position and orientation of workpieces proximate to which the material is to be applied. The requirement for precise mechanical workpiece alignment is eliminated, and the ability of the machine vision system to recognize size, configuration and topography of different workpieces affords greater manufacturing flexibility. The method includes application of flowable material in separate volumes and draws formation of the material to at least a semisolid state for packaging electronic components, and the electronic components so packaged are also part of the invention.

A compliant contact pin assembly and a contactor card are provided. A compliant contact pin assembly includes a contact pin formed from a portion of a substrate with the contact pin compliantly held suspended within the substrate by a compliant coupling structure. The suspension within the substrate results in a compliant deflection orthogonal to the plane of the substrate. The contact pin assembly is formed by generally thinning the substrate around the contact pin location and then specifically thinning the substrate immediately around the contact pin location for forming a void. The contact pin is compliantly coupled, in one embodiment by compliant coupling material, and in another embodiment by compliantly flexible portions of the substrate.

摘要:
An electrical contact for use with a semiconductor device, a carrier, a probe card, or another substrate includes a stereolithographically fabricated portion, which may comprise a plurality of at least partially superimposed, contiguous, mutually adhered layers. The electrical contact may include a dielectric core and a conductive coating on at least a portion thereof, or it may be completely formed from conductive material. The electrical contact may be rigid or flexible and resilient. Protective structures for use with flexible resilient contacts prevent deformation of such contacts beyond their elastic limits. Probe cards are also disclosed, as are methods for fabricating the electrical contacts, protective structures, and probe cards.
